My ex told me that was just my excuse to be a cheapskate and not get what she deserves. In the end, she got what she deserved, and it wasn't a diamond.
You can only tell the difference between the 2 if you have some expensive ass machine. I forget what it's called, but other than that, they are the exact same, and no one knows the difference
I thought about fooling her with a lab-grown one if I got one, but I just realized that why would I want to spend the rest of my life with someone who says "you don't *actually* care about that ridiculous thing, do you? You just want an excuse to not spend the money."
I thought you were gonna touch on the real issue of why diamonds are worthless. because pretty much one company owns the entire diamond industry so because they have A monopoly on it they literally control the prices of diamonds and they say that diamonds are a scarcity yet there’s how many diamonds all over the world and there’s a constant supply everywhere. Diamonds are not scarce there is plenty in The earth. The company that holds the Monopoly literally has a massive diamond fault we won’t run out of diamonds anytime soon. And not to mention that they even put out ads to discourage people from getting lab diamonds. Diamonds are one of the worlds biggest scams
Neptune's atmosphere contains a significant amount of methane. Methane is made up of one carbon atom bonded to four hydrogen atoms. As you go deeper into Neptune's atmosphere, the pressure and temperature increase dramatically. At depths of around 7,000 kilometers below the surface, the pressure can reach several million times that of Earth's atmosphere, and temperatures can soar thousands of degrees Celsius. Under these extreme conditions, methane molecules break apart. The carbon atoms freed from methane can then bond with each other, and potentially form diamonds.
Keep in mind that 'rain' here is not the same as rain on earth. It's more comparable to what happened to that submarine going to the titanic.
Yes, sound travels at different speeds depending on the medium. It travels faster thought solids than air. And it travels at different speeds through different atmospheres.
Thats so cool
I mean I knew that sound travels differently through, say, water than air. But I hadn't thought about the fact that other planets have different "air" so it would mess with sound. Space is rad
Yeah, space is pretty rad.
Even on earth, the speed of sound in air varies with temperature and pressure. For example, it’s lower at higher elevations. When people talk about THE speed of sound in air, they generally mean the speed of sound at standard atmospheric conditions, which is an agreed upon temperature and pressure (59 F at 1 atm pressure), or roughly the pressure and temperature at sea level on an average day.
FWIW, the speed of light is also dependent on the medium. Light travels more slowly through glass than air, which results in diffraction. It’s only the speed of light in a vacuum that’s a universal constant. You can even have particles that travel through a medium (say water) faster than the speed of light through that medium, which results in something called Cherenkov radiation. It’s a bit like a sonic boom.
Even through different air on earth we have to deal with this! Just to add a terrestrial example. As someone else replied the speed of sound is also affected by air temperature and pressure. This has to be taken into account by audio professionals setting up speaker arrays in large theatres or stadium type venues.
In these settings you might have a speaker stack at the front of the stage, another one 1/3 of the way into the crowd and another 2/3 of the way into the crowd.
The audio signal to each set of speakers after the first has to be slightly delayed to account for the speed of sound and ambient temperature has to be taken into account so even if the distances are the same, the delays will need to be slightly different for different venues depending on time of year/part of the world etc
on Earth, the speed of sound differs due to air pressure, and hence the speed of sound is higher at sea level than it is at altitude.
(temperature also affects this)
Ya, diamond rain at 1300 mph? What could humans even build that would withstand that? A car sized hollow diamond drone?? Even that would get sandblasted (diamondblasted) away pretty quick.
Only if you were traveling against the wind like an idiot though. With that big of a storm, you probably wouldn't even realize the atmosphere is 2000 kph because you'd be moving along with it.
> you probably wouldn't even realize the atmosphere is 2000 kph because you'd be moving along with it.
This is one of the only correct answers in this thread.
There was a weird point about 10 or 15 years ago where journalists suddenly started using the term "supersonic" in layman articles to describe the wind speeds of giant planets like Neptune. It's not great, because it gives the wrong impression that if you somehow found yourself there floating in the atmosphere, there would be sonic booms going off left and right. That's not what supersonic means here.
When we say "Earth's jet stream can exceed speeds of 100 m/s", that wind speed is measured relative to the surface. For giant planets, it's a little different; when we say "Neptune's winds can exceed 600 m/s" - that's relative to the speed of the planet _if it were rotating as a single solid body_. Figuring out that exact solid body rotation speed can be a little tricky, but we generally like to measure giant planet winds relative to the magnetic field, as that should also represent the core rotation speed. (There was a big kerfuffle about 15 years ago when we realized we had the solid body rotation of Saturn wrong, and the entirety of the wind values had to be offset.)
The only real sense in which it is "supersonic", then, is that the bulk motion of the atmosphere _relative to solid body rotation_ exceeds whatever Mach 1 is in that medium. If you were actually floating along Neptune's 600 m/s jet stream, you would not hear sonic booms, you'd just be moving along with the bulk motion of the atmospheric flow.

I meant as like a burst of wind. If you were stationary, and a magic force started blowing wind at you, how high do they crank it before you’re just dust.
I'm surprised storm systems can actually form even with very little sunlight. To be fair I only somewhat understand storm formation on earth and not other planets.
Makes me wonder if the atmosphere itself is moving that fast, does it make the shockwaves for a sonic boom all on it's own? Or does it have be a different object moving that much faster?
That's an interesting one to think about. Could it even carry sound if the medium is moving just as fast?
Since, I guess, things like density or pressure would affect the speed of sound, would the speed of sound be different within the storm than the rest of the atmosphere?
How would the fluid dynamic chaos of the storm affect its ability to carry sound?
If we put an (invincible) mic in there would it record pure silence?
PS. Do you have a sauce on the speed of sound on Neptune?
Thanks for your post :)
A commotion like that doesn't start over night. It must have started small several centuries before it was first discovered in 1830. That it's taking 300 years or more to die off suggests it's around 600 years old or more.
I feel like earth is such a weirdo planet just because it’s very different everywhere. Mars for example is kinda just red rock, or red dried up ocean bed with the ice caps for variety, compared to earth with vastly different climates. Maybe a Martian can correct me but I’ve always wondered why other planets (rocky) are just so uniform and similar kinda everywhere’s
Where do you guys go on vacation if the planet is so uniform. On Martian I knew suggested Mount Olympus and this one big canyon. Kept bragging about how everything on mars is way bigger except for the actual planet itself.
It looks uniform to your human eyes but we can detect the microscopic differences in temperature and rock composition which tickles the sensors on our feet differently. When my seasonal shift at the sun radiation conversion factory is over, I spend my vacation time in the Pit. Not expecting you to understand
> It must have started small several centuries before it was first discovered in 1830.
If you go back in the historical observation record, the Great Red Spot was first observed in 1685 by Cassini, then after the late 1600s it seemed to just disappear for a century or two as the entire latitude band clouded over - literally no observations of it were made for 175 years, in spite of plenty of telescopes that could easily have seen it.
It was only first re-observed in 1869 by Joseph Gledhill, at the time referred to as "Gledhill's Ellipse". Reference from 1898 [here](http://adsabs.harvard.edu/full/1898MNRAS..58..488D). (I'm yet to see any references that actually verify the earlier 1830 re-discovery date that's sometimes claimed, and the original source material linked above actually contradicts that.)
Point being, it could have just clouded over for almost two centuries...or maybe it did disappear entirely, and the potential vorticity gradient at that latitude that just makes a giant vortex want to form there.
Thanks. I knew the 1600's were important for Jupiter, but the faulty source I looked up for that post compelled me to mentally write it off as the discovery of Jupiter's big moons.
How do our jet streams compare? [They’ve certainly got the speed to tackle The Great Red Spot](https://www.noaa.gov/jetstream/global/jet-stream)
[Plus, the jet stream is at least 4,000 years old](https://cmes.utah.edu/news/warmwestcoldeast.php).
Mph isn’t a great way to measure the energy of a storm because the density of the atmosphere has a much stronger effect on the speed of the storm than the energy does.
That’s a sustained storm, too. The 1990 Plainfield tornado had winds estimated up to nearly 320mph. The storm was only active for 30 minutes, though, and the peak winds weren’t likely for very long.
And an actually-correct number probably wouldn't help because I don't have any referents :-)
All I was wondering is if it's super-thin atmosphere like how wind speeds on Mars can get very high but there's so little air that they don't actually have much force.
Here's an AI answer:
Neptune's atmosphere is thick and windy, and is made up of 98% hydrogen and helium, with the remaining 2% mostly methane. The methane absorbs red light from the sun and reflects blue light back into space, giving Neptune its distinctive blue tint.
I was curious as to what the answer to the question was, so I googled it and Google AI gave me that info. I was just trying to be helpful and I thought the information was interesting. Didn't think it deserved down votes but whatever. 🤷🏻 Fuck me right?
Wow that's a new one for me. I have heard about his math ideas, but not about any of this.
Best part is that it's not even a new idea. *World's in Collison* was published in 1950 by Immanuel Velikovsksy and posited that Venus was ejected from Jupiter, did a bunch of wild-ass physically impossible shit and eventually settled into it's current orbit. Velikovsky contended that this was the cause of all the perceived similarities that different culture's cataclysm myths share. It was not well received.
At least have an original crackpot idea...
I'll be honest, I thought he did a better job playing that role than Don Cheadle did but it still makes me laugh that he horribly misjudged his value in that franchise.
This was done by tracking cloud motions in images of Voyager's ISS instrument, thereby constraining Neptune's winds to be −400 m s−1 (retrograde) at the equator, with a prograde jet of about +250 m s−1 at latitude 70◦S (Limaye & Sromovsky 1991; Sromovsky et al.
Yea sorry I have no definite answer 😅 assuming based off of the movements of the clouds over a period of time, measured against the size of the planet. That's me guessing though.
Imagine that, on Jupiter, your office is on the other side of the storm, and every day you think how you could drastically reduce your commute time by cutting through the storm. You could do it, you could do it, you tell yourself! Cmon now, don’t be a wuss!
It's silly to even have a comparison with earth. A localized hurricane on earth vs a seemingly endless storm on Jupiter that's almost the size of the entire earth.
Thin air at thousands km/h you can barely feel it.
A few hundred km/h of dense air and you will melt.
So the speed only doesn't give the picture of how much brutal an alien planet atmosphere could be.
Neptune's wind speed becomes even more unimaginable when you consider the strongest tornado recorded on Earth by Doppler Radar was recorded at 302mph, and look at the destruction even a much smaller tornado can cause here.
The most intense storm in our solar system is actually Sandstorm by Darude. Just thinking about the first beat drop makes the hair on the back of my neck stand up
Is it considered "wind" if it's not oxygen? What is it made of? Is this some other element in gas form moving really quickly? Would love to know the chemistry behind it if anyone knows
100% of the wind on our planet has oxygen in it, though, right? Is it easier for wind on other planets to go faster because of the chemical make-up of the air? I have so many questions I've never thought if before.
Gas giants can have stronger winds that last for hundreds of years because they have no mountain ranges to catch and dissipate said winds. It doesn't have anything to do with oxygen.
Even though I get what you're trying to say, oxygen is still just a fifth of the atmosphere of the Earth. Majority of it is nitrogen.
And oxygen is good to make things burn, not to make wind.
If I could be just a little bit pedantic for a minute :) (sorry!!)
Most atmospheric effects are driven by the sun, where it heats up a portion of the atmosphere where it shines, causing the gases to expand and push outwards. The cooler or darker parts of the atmosphere are more dense, and become like pits into which the heated air falls or gets sucked into. These are your so-called high-pressure and low-pressure systems. Wind is what we get when air flows from high-pressure areas into low-pressure ones. The thing about atmosphere is that there is no force trying to slow it down in its rotation like there is if we spin something like a basketball at sea level, where the force acting to slow it down is friction with the still air. The atmosphere rotates like the planet does. They both are subject to gravitational force pulling down, and centrifugal force pushing outward, though.
One of the coolest things I've ever read about was in the What If books by Randall Munroe of XKCD, where if the earth were to suddenly stop spinning instantaneously, but the atmosphere were to keep going, we would be instantly subjected to 1000mph winds which would effectively raze all above-ground structures between the 45th parallels north and south, covering most human population centres. I assume the same would be true if the atmosphere stopped spinning while the earth continued to rotate!
Wind is just the movement of air or other gases relative to a planets surface, essentially. Any gas will suffice. When you have a planetary object with a gaseous atmosphere, anything disturbing a kind of motion equilibrium between the solid and the gas would be a kind of wind. Liquid has the same kind of thing going on, but they're called "flows". Liquids and gasses have similar dynamics, just at different densities.
So in short, if it's a gas, it's wind; if it's a liquid, it's a flow. Gasses and liquids can both have currents. Therefore to answer your question, yes, it would still be called wind even in non-oxygenated atmospheres.
If you consider asking how the chemical makeup of an atmosphere affects weather and wind, a stupid question, then maybe science and math isn’t for you bud
The question doesn't have a damn thing to do with chemistry and everything to do with definition. If you can't tell that difference, then maybe air isn't for you.
>doesn’t have a damn thing to do with chemistry
I hate to break it to you but gases and elements such as those that make up atmospheres definitely involve chemistry.
>maybe air isn’t for you
If you’re so smart and it was such a stupid question can you please explain in full industry jargon the answer to it? Can you fully explain the differences in atmospheres in our solar system and how they breed different heather patterns?
The question was "Is it considered 'wind' if it's not oxygen?" For purpose of this conversation, nobody gives a flying fuck what's healthy. You'd add a lot more to this subreddit by choking to death on an atmosphere that's somehow not windy when it moves.
Nice deflection. So instead of answering it you just doubled down on proving you don’t know it but still think it’s a stupid question.
>You’d add more to this subreddit by choking to death
What are you 9 years old? Can’t think of an intellectual rebuttal other than that? Classy
I just can't comprehend how fast/hot/dense matter can be. It's so foreign to me and maybe that's just being human, because I really have no need to be able to comprehend that.
I find it interesting that the further you get away from the Sun, the faster these storms get. I wonder if solar energy by any chance slows down the winds. If anyone can explain why Jupiter is so fast in simple terms, that would be interesting. I had thought that the Great Red Spot was the fastest and most intense, but this is an interesting surprise. I also find it very shocking that Hurricane Patricia is almost as fast as the Great Red Spot. Do storms slow down over time by any chance? I do know that some of these storms have been raging for millenia.
Holy goodness… winds nearly the speed of sound on Neptune… Speed of sound on Neptune is ~1,350 mph
Rains diamonds as well on Neptune
But what does that mean?
It’s theorized that it can literally rain diamonds far down in Neptune’s atmosphere
Damn, I had other plans but guess I'm building a spaceship to go get some Neptune diamonds tomorrow. Gonna be a diamond trillionaire
Until diamonds are practically worthless lmao, why spend too much at jeweler when I can make a quick stop at Neptune?
Diamonds are already worthless because they can be grown in labs now. The only reason to get natural ones is to support slave labor and mining deaths
My ex told me that was just my excuse to be a cheapskate and not get what she deserves. In the end, she got what she deserved, and it wasn't a diamond.
It's not real love without the blood on your hands!
Blood diamond
You can only tell the difference between the 2 if you have some expensive ass machine. I forget what it's called, but other than that, they are the exact same, and no one knows the difference
I thought about fooling her with a lab-grown one if I got one, but I just realized that why would I want to spend the rest of my life with someone who says "you don't *actually* care about that ridiculous thing, do you? You just want an excuse to not spend the money."
Are we talking lab grown diamonds? Or I forget the name... messonite or something like that?
I do not buy diamonds for their values or beauties. I buy them to support the enslavement and death of African children
Smd
Are lab grown diamonds also good for diamond tipped tools?
better. real diamonds often have faults in the crystal structure, called inclusions. labgrown can be 100% perfect.
Yep.
Not only are they also good for them, that's mainly how they get the diamonds for those
Canada has slave free mines. Many workers make damn near six figures on a 2x2 rotation.
But most diamonds come from much less well off countries with exploitative and downright slave-like mining.
I'm just saying that there are natural alternatives available, and more places would offer them if people asked for them instead of lab grown.
It’s the suffering that makes it special 😊
I dont like that slave stuff... I prefer graverobbing. Like a reverse tooth fairy I says I am.
I thought you were gonna touch on the real issue of why diamonds are worthless. because pretty much one company owns the entire diamond industry so because they have A monopoly on it they literally control the prices of diamonds and they say that diamonds are a scarcity yet there’s how many diamonds all over the world and there’s a constant supply everywhere.

Just buy some cheap junker ship from the seedy shop owner down the road, collect diamonds in secret, and control the economy
I bet Neptune diamonds would cost premium bucks
Rn? absolutely, but if we had spaceships that made it easy to get the price would drop to near dirt
You'd be rich without the diamonds if you could figure out how to make a trip to Neptune a "quick stop".
You can definitely make a quick stop at Neptune, but you certainly won't be leaving.
Wait till you see what we pull out of Uranus!
There not rare anways just part of the biggest scam ever lol
Please don’t let it get lost and then send a crew to go save the ship.
No, you would just become a diamond.
I understand that, I apparently asked the wrong question. I should have asked "why does it rain diamonds?"
Imagine one day we are advanced enough to mine diamonds on Neptune
Wanna go get some?
Theory,not proven, plus those diamonds would be tiny
Neptune's atmosphere contains a significant amount of methane. Methane is made up of one carbon atom bonded to four hydrogen atoms.

De Beers feels threatened.
The pressure is high enough that at some very deep parts of neptunes atmosphere, carbon is literally squeezed into diamond and falls from the sky
How does rain work on gas giants? Diamonds just drop but become increasingly slower as they get closer to the center. Then evaluate on the way there?
"Precipitate" might be the more honest verb here.
Wait is the speed of sound different depending on atmosphere?
Yes, sound travels at different speeds depending on the medium. It travels faster thought solids than air. And it travels at different speeds through different atmospheres.

on Earth, the speed of sound differs due to air pressure, and hence the speed of sound is higher at sea level than it is at altitude. (temperature also affects this)
Also the direction of wind affects
Would that make pitch super high like everyone talking after inhaling helium?
I believe it makes everyone's pitch super deadzed.
Ya.. There's no hearing in this one.. Because we be dead lol.
Ya, diamond rain at 1300 mph? What could humans even build that would withstand that? A car sized hollow diamond drone?? Even that would get sandblasted (diamondblasted) away pretty quick.
NASA is in talks with Nokia for such a spacecraft last I heard
Oh... oh this is solid.
lol I just came from another comment section praising Nokia’s unparalleled strength
It would make everyone super dead.
At what mph, all other factors aside, would the wind speed alone simply kill you.
Only if you were traveling against the wind like an idiot though. With that big of a storm, you probably wouldn't even realize the atmosphere is 2000 kph because you'd be moving along with it.

Does gravity effect the rate in which sound travels?
What provides the energy for those neptunian winds?
Apparently its due to the planet's internal heating. The source of this heating is unknown.
They basically already know what it is, though. Radioactive decay and tidal torque.
Wouldn't the pressure of gravity also generate heat in the core?
Aquaman
It’s obviously Neptunes Trident…Aquaman is only effective in water.
My neighbor's uncle works at NASA. Most of Neptune is actually water.

Neptune storm was gone in a few years
How the hell u gon be the biggest gas planet in the solar system with that weak ass storm.
That storm on Jupiter has been going on for eons...I believe it's become smaller within our life time. I bet it was super strong when it first started
A commotion like that doesn't start over night. It must have started small several centuries before it was first discovered in 1830. That it's taking 300 years or more to die off suggests it's around 600 years old or more.

Jupiter ain't got nothing to prove to anyone.
planet olympics
That storm is about 3 times the size of the Earth though, and much larger than all the other ones.
Well I think this comparison proves size doesn’t matter. It’s all about how fast it spins
My wife agrees.
I have so many questions
How do our jet streams compare? [They’ve certainly got the speed to tackle The Great Red Spot](https://www.noaa.gov/jetstream/global/jet-stream) [Plus, the jet stream is at least 4,000 years old](https://cmes.utah.edu/news/warmwestcoldeast.php).
Mph isn’t a great way to measure the energy of a storm because the density of the atmosphere has a much stronger effect on the speed of the storm than the energy does.
Whatever storm lets me fly around at the fastest speeds if thrown inside is the storm I want. If Jupiter can do that I take it back
Neptune's farts create more wind.
Why's Neptune getting blamed for Uranus' crimes?
Got me over here thinking about that Calvin & Hobbes panel staring up at the stars yelling "shit's weak."
Surprising to think our little planet can produce winds that approach Jupiter's Great Red Spot.
But the Great Red Spot storm has been storming for possibly hundreds of years. The spot was first documented about 350 years ago.

I guess irrelevant crap is still better than overtly wrong crap...
Hmm. Nah.
AI stands for Absolutely Irrelevant
Why would you post an ai answer?
I was curious as to what the answer to the question was, so I googled it and Google AI gave me that info. I was just trying to be helpful and I thought the information was interesting. Didn't think it deserved down votes but whatever. 🤷🏻 Fuck me right?
According to Terrance Howard, a moon is going to pop out of the red spot on Jupiter! And , here's the really crazy part, lots of people believe him!!
I mean it was supposed to become a sun and have a bunch of planets around it that we can colonize in 2010 and I was disappointed.
Great book. I'd miss nighttime though personally
Wow that's a new one for me. I have heard about his math ideas, but not about any of this. Best part is that it's not even a new idea. *World's in Collison* was published in 1950 by Immanuel Velikovsksy and posited that Venus was ejected from Jupiter, did a bunch of wild-ass physically impossible shit and eventually settled into it's current orbit. Velikovsky contended that this was the cause of all the perceived similarities that different culture's cataclysm myths share. It was not well received. At least have an original crackpot idea...
I have no problem with wacky ideas for sci fi stories. When pseudoscience conmen make up this shit and people believe it, its bad for society
Me either. I feel I should mention that *World's in Collision* is not sci-fi, however. It was intended as a serious scientific treatise.
I mean, he's the original War Machine...
I'll be honest, I thought he did a better job playing that role than Don Cheadle did but it still makes me laugh that he horribly misjudged his value in that franchise.
Next time, baby.
That's terrance-ology 101
Saturn looks intense.
Saturn’s storm is hexagonal 
I mean, its bestagon
What in the worlds..? Now that is interesting as hell
How do they know the speed of it?
This was done by tracking cloud motions in images of Voyager's ISS instrument, thereby constraining Neptune's winds to be −400 m s−1 (retrograde) at the equator, with a prograde jet of about +250 m s−1 at latitude 70◦S (Limaye & Sromovsky 1991; Sromovsky et al.
Yes
Someone licked their finger and stuck the tip in. Then stuck their finger in.
Ok you got me 😂 I was genuinely curious
Yea sorry I have no definite answer 😅 assuming based off of the movements of the clouds over a period of time, measured against the size of the planet. That's me guessing though.
Maybe one day that energy could be harvested to power outposts out there
Why do I feel like This is a Mass Effect thing....
Can we add the sun to this thing? How fast does a solar wind go?
Is there a phenomenon similar to a storm on the sun? There are sun storm but that's something different as far as I remember my physics classes...?
Imagine that, on Jupiter, your office is on the other side of the storm, and every day you think how you could drastically reduce your commute time by cutting through the storm. You could do it, you could do it, you tell yourself! Cmon now, don’t be a wuss!
"Multiple Earths away" is only a practical distance for regular travel if the likes of Mach 10 is easy to achieve.
“Must be taking a poop” ~ Terrence Howard
It's silly to even have a comparison with earth. A localized hurricane on earth vs a seemingly endless storm on Jupiter that's almost the size of the entire earth.
Speed isn't everything, we should check the density of the atmosphere at that altitude and so compare the forces of the wind per squared meter.
Can you explain more please
Thin air at thousands km/h you can barely feel it. A few hundred km/h of dense air and you will melt. So the speed only doesn't give the picture of how much brutal an alien planet atmosphere could be.
Thank you
Neptune is a terrifying place.
Neptune: “we could use some breeze”
Neptune's wind speed becomes even more unimaginable when you consider the strongest tornado recorded on Earth by Doppler Radar was recorded at 302mph, and look at the destruction even a much smaller tornado can cause here.
That’s seriously wild. Mix in rain and I can’t fathom what that does to a person
I believe Uranus has the biggest thunderstorm mankind has ever seen
Would the Neptune storm rip me to shreds, like I know 1300 mph would crush, but like would I turn to swiss cheese? Genuinely curious
The most intense storm in our solar system is actually Sandstorm by Darude. Just thinking about the first beat drop makes the hair on the back of my neck stand up
Is it considered "wind" if it's not oxygen? What is it made of? Is this some other element in gas form moving really quickly? Would love to know the chemistry behind it if anyone knows
75% of the wind on this planet isn't oxygen. Wind isn't oxygen-dependent.
100% of the wind on our planet has oxygen in it, though, right? Is it easier for wind on other planets to go faster because of the chemical make-up of the air? I have so many questions I've never thought if before.
Gas giants can have stronger winds that last for hundreds of years because they have no mountain ranges to catch and dissipate said winds. It doesn't have anything to do with oxygen.
Idk why you’re being downvoted for genuine curiosity…
Even though I get what you're trying to say, oxygen is still just a fifth of the atmosphere of the Earth. Majority of it is nitrogen. And oxygen is good to make things burn, not to make wind.
Wind is the force of the atmosphere we feel due to the rotation of the planet.
If I could be just a little bit pedantic for a minute :) (sorry!!) Most atmospheric effects are driven by the sun, where it heats up a portion of the atmosphere where it shines, causing the gases to expand and push outwards. The cooler or darker parts of the atmosphere are more dense, and become like pits into which the heated air falls or gets sucked into. These are your so-called high-pressure and low-pressure systems. Wind is what we get when air flows from high-pressure areas into low-pressure ones. The thing about atmosphere is that there is no force trying to slow it down in its rotation like there is if we spin something like a basketball at sea level, where the force acting to slow it down is friction with the still air. The atmosphere rotates like the planet does. They both are subject to gravitational force pulling down, and centrifugal force pushing outward, though. One of the coolest things I've ever read about was in the What If books by Randall Munroe of XKCD, where if the earth were to suddenly stop spinning instantaneously, but the atmosphere were to keep going, we would be instantly subjected to 1000mph winds which would effectively raze all above-ground structures between the 45th parallels north and south, covering most human population centres. I assume the same would be true if the atmosphere stopped spinning while the earth continued to rotate!
Getting downvoted for asking a question. Reddit moment.
I think most people didn’t read past the first sentence and thought they were being a smartass.
I wasn't trying to be but I'm not afraid of downvotes. Unfortunately nobody is giving me a real answer so I'll go try and figure it out myself
Wind is just the movement of air or other gases relative to a planets surface, essentially. Any gas will suffice. When you have a planetary object with a gaseous atmosphere, anything disturbing a kind of motion equilibrium between the solid and the gas would be a kind of wind. Liquid has the same kind of thing going on, but they're called "flows". Liquids and gasses have similar dynamics, just at different densities. So in short, if it's a gas, it's wind; if it's a liquid, it's a flow. Gasses and liquids can both have currents. Therefore to answer your question, yes, it would still be called wind even in non-oxygenated atmospheres.
Ty :)
Don't let that other subreddit fool you, there's such a thing as stupid questions.
If you consider asking how the chemical makeup of an atmosphere affects weather and wind, a stupid question, then maybe science and math isn’t for you bud
The question doesn't have a damn thing to do with chemistry and everything to do with definition. If you can't tell that difference, then maybe air isn't for you.
>doesn’t have a damn thing to do with chemistry I hate to break it to you but gases and elements such as those that make up atmospheres definitely involve chemistry. >maybe air isn’t for you If you’re so smart and it was such a stupid question can you please explain in full industry jargon the answer to it? Can you fully explain the differences in atmospheres in our solar system and how they breed different heather patterns?
The question was "Is it considered 'wind' if it's not oxygen?" For purpose of this conversation, nobody gives a flying fuck what's healthy. You'd add a lot more to this subreddit by choking to death on an atmosphere that's somehow not windy when it moves.
Nice deflection. So instead of answering it you just doubled down on proving you don’t know it but still think it’s a stupid question. >You’d add more to this subreddit by choking to death What are you 9 years old? Can’t think of an intellectual rebuttal other than that? Classy
Does that kind of wind just atomize anything in it? I can’t imagine.
Relative speed, on Neptune that could be the equivalent of a Patricia, or Red Spot?
Does it really rain diamonds on Neptune ? How do we measure the speed of the storm in Neptune ?
Where’s the hexagon?
Using the first wind-chill formula I could find online, that puts the real feel on neptune well below absolute zero. Sweet.
There is a video called “ falling into ….”, where they simulate falling into planets. It’s very very scary
I would say Neptune for winds 2x the speed of sound
I wonder if that’s how the eye of the Sahara was made.
I just can't comprehend how fast/hot/dense matter can be. It's so foreign to me and maybe that's just being human, because I really have no need to be able to comprehend that.
Saturn looks like one of those old car cigarette lighters 😂
Neptunes great dark spot isn’t there anymore
Neptune no New Mexico
Neptune: hold my beer
Honestly a little surprised that the gap between a hurricane on Earth and Jupiter's Great Red Spot is only about 50mph. Pretty cool!
Oh dear Neptune....
I find it interesting that the further you get away from the Sun, the faster these storms get. I wonder if solar energy by any chance slows down the winds. If anyone can explain why Jupiter is so fast in simple terms, that would be interesting. I had thought that the Great Red Spot was the fastest and most intense, but this is an interesting surprise. I also find it very shocking that Hurricane Patricia is almost as fast as the Great Red Spot. Do storms slow down over time by any chance? I do know that some of these storms have been raging for millenia.
I’d like to fly a kite on Neptune
"We are number 4, we are number 4" [chanting with false pride]
This is just screaming to be made into a meme
Actually, the northern hex storm on Saturn has sustained winds of exactly 333 mph. Those who know, know.
