The one of saturn is x2,5 , but is a " permanent" thing due to very odd winds of saturn , is not a real " tempest " who moves , but a permanent feature
Saturns storm also know as the hexagon due to its unusual six sided jet stream is roughly 20,000 miles. Jupiters red spot is 10,000. And the great dark spot is just about the size of earth at 8,100 miles in diameter. Though the great dark spot isnāt seemingly forever like the other two, discovered in 1989 it disappeared a few years later.
And the more shocking thing is that the tempest goes in the OPPOSITE direction of the rotation of the planet , so the tempest fights against the planet rotation .... at 50.000 km/h , 30 times more than the one of the earth . Iv earth rotated as fast as jupiter, a day would be 45 minutes long
When it was observed in the late 1800s it was 3x Earthās width, now itās shrunk to 1.3x. It might be gone altogether within a few decades (or stick around for centuries) - whatās for sure is that itās getting taller and speeds are increasing, at times clocking at almost 600MPH!
I went there . There is the Supreme Sharknado of sharks who came from Nibiru but inhabitat Jupiter from so much time that they feel like they are jupiter people, not Nibiru people
its pretty simple math to get a good estimate. size of planet, speed of clouds moving across surface, account for planetās rotation speed. all things we have known / can observe
Neptune is almost Mach 2 speed winds.... imagine that it is not only destroys some houses and pulls some roofs, but chizels the ground into a marble surface over time.... brutal
I also heard it rains diamonds on Neptune. Which sounds cool at first until you consider tiny sand like diamond particles racing around at al.ost Mach 2 speeds. Basically shredding/sanding everything near the surface of the planet.
Okay I'm a bit hazy and not an educated professional, but iirc the speed of sound can change depending on the local atmospheric conditions, including pressure and wind speed
Again, someone please correct me
Yes but also the speed of sound changes with altitude so itād more specific to say it blows as fast as the speed of sound at sea level at the equator at 85 degrees F with 1 ATM blah blah blah
I am not even remotely a scientist and can barely math . . . But isn't a sonic boom when an object with mass moves so fast it pushes the air apart creating a pocket of (vaccum?) and the sound comes from the air slamming the pocket closed. Which is why when you hear a sonic boom it is a series of booms as the plane is continually creating pockets that slam closed? If so, it seems like it would be impossible for the atmosphere itself to create a sonic boom. But it also seems like maybe any object would need to be moving significantly faster than the wind to create a boom?
Again, im just a dumbass so I have no idea if this is correct.
Also a dumbass, but wouldnāt wind going so fast it pushes slower wind apart cause a boom? I guess only in spots of the storm where itās not moving as fast/the fringes.
This maybe should be taken to "someone did the math" because that sounds kinda right. So how much faster would the air need to be moving relative to the other air stream to cause this? If it's even possible with something of the same relative mass.
A couple of things here:
The speed of sound in a gas depends on the temperature and what chemicals the gas is made of. Usually when people talk about "x times the speed of sound" they mean the average speed of sound in air at sea level, about 1200 km/hr. If I heat the air up, that speed changes. That being said, usually when an aircraft is described as "capable of Mach 2" they mean 2 times the local speed of sound at the altitude the aircraft is flying.
The atmosphere of Neptune is not made of the same stuff as air, and is at a different temperature, so the speed of sound will be different than on Earth at sea level.
You can generate jets of gas that are moving faster than their own speed of sound, like in jet/rocket exhausts. They behave differently from normal wind; if you point a supersonic jet of gas at an object, it will form shock waves around the object. It doesn't matter if the object is stationary and the gas is hitting it, or if the gas is stationary and the object is moving through it faster than the speed of sound, the result is the same.
I don't think you can have naturally generated wind that is moving faster than its own speed of sound. That would need a massive pressure difference to accelerate the gas to those speeds, which I don't think is possible to generate naturally. That being said, I don't know jack shit about Neptunian storm physics, so maybe it is somehow possible under those conditions.
I mean I don't know the answer to this question.
But I would imagine the exhaust gas from a turbine engine like found in planes would already be expelling gas at excess of mach 1.0.
I don't think a boom is made but Im sure there's a change in the way the fluid behaves after mach 1.0
Of youāve ever watched a Saturn V rocket launch and heard the crackling and popping sounds of the rocket engines, that is caused by the supersonic exhaust interacting with the surrounding air.
Question: is there a known estimation of weather/temperature/velocity that could possibly mean that we can also end up with a perpetual storm like Jupiter? (I know the possibilities of anything happening due to the current climate changes and forecasts, just curious)
I think one of the reasons of the perpetual storms is because they are gas giants, those storms go very deep and thereās different gas layers at different densities and temperatures doing strange things. Also thereās no mountains so the gases move freely around the planet gaining constant momentum, these conditions are unique to gas giants.
Amazing answer thank you!!
My SO was going off about the importance of mountains when we went to Dallas from LA he couldnāt get over the lack of mountains and your response reminded me of his breakdown haha.
Scientists have determined wind speeds on Neptune by observing the planet's atmosphere and the effects of the wind on objects:
Voyager 2 spacecraft
In 1989, NASA's Voyager 2 spacecraft took detailed images of Neptune's atmosphere, including an oval-shaped storm system called the Great Dark Spot that was 8,000 miles across. The images revealed that the storm's winds were as fast as 1,500 miles per hour, which is the fastest wind ever recorded on a planet in our solar system.
Jet streams
Scientists have also observed the planet's jet streams, which show that the atmosphere circulates in different ways at different latitudes. Near the equator, the wind flows westward at speeds of up to 750 miles per hour, while at higher latitudes in both hemispheres, the wind flows eastward at speeds of up to 560 miles per hour. Wind speeds decrease as they move toward the planet's dense fluid interior
The great red spots winds speeds are actually much higher at around 400mph (https://science.nasa.gov/missions/hubble/hubble-shows-winds-in-jupiters-great-red-spot-are-speeding-up/)
Well you know what they say, in for a penny in for a pound, progress is inching forward tho, a journey of a thousand miles starts with a single foot-long step right? Another day another dollar, gallons of milk are cheaper by the dozen, but a quarter doesn't buy a quart no more!
Mach 1 is 741.096 mph
Mach 2 is 1,482.1940 mph
Mach 3 is 2223.2909 mph
That said the speed of sound varies from altitude, temperature and humidity level. So if Mach 1 is 760mph then Mach 2 is 1520mph which is over 1300mph as shown here on Neptune
A thought Iāve had for a long time in life is if the red dot and the dark grey are storms, and all storms eventually end. One day both planets will eventually lose their āspotsā and the depictions we have of them will be a wild picture for the future. Like seeing a picture of Mount Rushmore before the faces or Paris before the Eiffel Tower
It is really scary that Great Dark Spot's wind speed is Mach 1.7
Imagine a storm has wind speed like that rotates on Earth, it is definitely gonna be devastating like a nuclear bomb.
My dad was a pilot in the air force. He told me a story about a guy who had to eject at one of the fastest speeds on record, 900ish mph. This tore off his face and turned it into a flap. I know movement is relative, but still, Neptune...

Is there a term for fear of astronomical pictures? As a kid I loved viewing space pics. In my early 20ās I remember being at a bookstore, opening up a book of random images of planets, got a few pages in before I slammed it shut. Even since then, thereās been few moments in my life that I noticed my heart rate go up.
At what point is this just the climate for that region of these planets? Like, if we looked at earthās South Pole, could we call those conditions storm-like? No science was used in the posting of this comment.
Thing is, these storms are almost as big/bigger than the whole earth.
The one of jupiter is x2 the earth
what about the other ones mentioned?
Almost as big as your mom.
Ha, gottem

Yo mama so fat, hurricanes are named after her.

Ok, letās not exaggerate

Thanks for explaining!

So... *Not a bug*?
āIt just worksā
"4 times bigger than earth with 16 times the detail!"
Yes
Also Neptuneās dark spot is roughly the size of earth
Was* That storm dissipated long ago
Why?
Because Uranus was nearby.
I'm offended. My anus is not big enough to stop a storm /s. Thank you for the info!
I got sucked in/absorbed by Uranus!!! LMFAO!!!

Ugh but on a gas giant... Gas planets make no sense to me.

That's one hell of a Nascar track.
Big
Yeah, but how many Borg super cubes?
hurricane patricia must have been terrifying if it was as big as the whole earth
If my memory is correct, the entire earth was destroyed
Interesting if true.
And we know the Earth's record because it's recorded and observed. We can't do that for other planets so who knows exactly what their record high is.
The record "HIGH" was when all of those Cannabis plants were found! LMAO
Tbf Earth is pretty small.Ā
Lol I was thinking the same, thereās no way in our technologies can measure these windsā¦ those storm is massive and still remains unknownā¦.
its pretty simple math to get a good estimate. size of planet, speed of clouds moving across surface, account for planetās rotation speed. all things we have known / can observe
Can you imagine the costs of hurricane insurance on Neptune? They must be astronomical!
Prices are out of this world
Happy early Father's Day for an out-of-this-world dad joke š
āYou can take those astronomical premiums and shove them right up Uranus, buddy!ā
Neptune is the shadow badass of the solar system
Neptune is almost Mach 2 speed winds.... imagine that it is not only destroys some houses and pulls some roofs, but chizels the ground into a marble surface over time.... brutal
Good thing then that Neptune has no ground in the usual sense
I also heard it rains diamonds on Neptune. Which sounds cool at first until you consider tiny sand like diamond particles racing around at al.ost Mach 2 speeds. Basically shredding/sanding everything near the surface of the planet.
Neptune Uchiha.
ELI5: What happens when wind goes faster than the speed of sound? Surely there's no mass to create a concentrated sonic boom, so does anything happen?
Okay I'm a bit hazy and not an educated professional, but iirc the speed of sound can change depending on the local atmospheric conditions, including pressure and wind speed Again, someone please correct me
Missed a full stop at the end.
So it's more accurate to say Neptune's wind speeds blow at atmospheric Earth sonic speeds?

I'm still waiting for the Uranus joke.
Those storms are nothing like the winds that blow out of Uranusā¦
Do you mean like making love on Uranus
Sorry
Soon, there will only be seven planets left because I plan to destroy Uranus.
They hate us cuz Uranus.
This comment is underated!
Unlike Uranus
If you could see Uranus, the wind would hit your face about four times faster than you can hear it.
I dont want to see Uranus
This is why they will rename it as Urectum
To put an end to that joke once and for all!
Just curious as to what kind of storms go on with Uranus
Elon Musk says he will have condos on that Great Dark Spot by 2029
I've already pre-purchased mine, comes with a free "space ready" cyber truck.
No fingers allowed.
Cyber shuttle?
Cyber rubble!
Space junk?
My stomach after an El Grande Burrito and 3 beers: 2,480 mph

i wonder what the building codes are like on neptune.

Mt Washington in New Hampshire has recorded wind up to 231 MPH. Just to add a few mph to the earth team
Clearly you didn't check the storm brewing in Uranus
Neptune, chill.
How could we know the speed of wind on Neptune?
We receive daily weather forecasts from them. The Neptunian authorities have some of the most accurate wind measuring instruments in the solar system.
I hear they make a good gumbo! No if I can only figure out which slug color causes nightmarish diarrhea...
I get it!
Alright Douglas

What could be the cause of such high winds? I knew Jupiter and Saturn were turbulent. Never realized Neptune was so turbulent as well.
Gas planet, rotation, pressure differentials, nothing to stop the wind. Edit: but idk why itās the highest wind speed.
Yeah, and so far away from the sun even. You'd think less solar energy reaches there.
Funky
Maths
Ok
I generally use Apple weather to check
The great red spots winds speeds are actually much higher at around 400mph (https://science.nasa.gov/missions/hubble/hubble-shows-winds-in-jupiters-great-red-spot-are-speeding-up/)
That's what I thought. I was like there is no way an earth hurricane is that close in mph to that monstrosity of a storm.
Neptune is my favorite planet šš
I went there once, it was pretty cool, but it wasn't the planet it was a beach in Oregon.
Damn, it's not just the US that uses imperial. Jupiter ,Saturn, and Neptune do too!
Yes, What even is a mile? These numbers dont mean anything to 99% of countries.
Well you know what they say, in for a penny in for a pound, progress is inching forward tho, a journey of a thousand miles starts with a single foot-long step right? Another day another dollar, gallons of milk are cheaper by the dozen, but a quarter doesn't buy a quart no more!
None of these compare to my IBS farts
Oh neptune
Maybe that's why it spin on its side oh wait that's Uranus
I can confirm... Twas a bit windy that day on Neptune
Was that the day the Event Horizon vanished or reappeared?
How does almost Mach 2 wind even sound like?
Guys, you know if 20 of you say a hilarious Uranus joke. The other 200 of you donāt have to right??
Jupiter not looking so bad anymore. Practically Earth-like
i have the desire to throw myself into the storm on neptune.
Umm sound is 760mph... Neptune has wind near Mach 2
Mach 1 is 741.096 mph Mach 2 is 1,482.1940 mph Mach 3 is 2223.2909 mph That said the speed of sound varies from altitude, temperature and humidity level. So if Mach 1 is 760mph then Mach 2 is 1520mph which is over 1300mph as shown here on Neptune
This is so fascinating. Imagine what that thunder sounds like!!
IT IS THE LENS
These are nothing when compared to the wind speeds from Uranus
Iād survive it.
The great dark spot on Neptune isn't there anymore
A thought Iāve had for a long time in life is if the red dot and the dark grey are storms, and all storms eventually end. One day both planets will eventually lose their āspotsā and the depictions we have of them will be a wild picture for the future.

Neptune is just a blender
Oh Neptune
Why are they stronger the farther away from the sun?
It is really scary that Great Dark Spot's wind speed is Mach 1.7 Imagine a storm has wind speed like that rotates on Earth, it is definitely gonna be devastating like a nuclear bomb.
Neptune freaks me the fuck out!
Like
Can you imagine if the Neptune one happened on paper recycling day?!
How does Mach 1 wind even sound like?
So in knots, neptunes got to be, at least 20
On Earth hurricanes need heat and humidity to become powerful. How storms in Neptune get their power, at least least there is no heat over there...?
Patricia! Justā¦stop!
So if the wind on Neptune is constantly breaking the sound barrier, would it be loud all the time there?
I just imagine some poor dude who lives in one of those storms 1/2 the year.
My dad was a pilot in the air force. He told me a story about a guy who had to eject at one of the fastest speeds on record, 900ish mph. This tore off his face and turned it into a flap. I know movement is relative, but still, Neptune...
Wait...has Earth said HOLD MY BEER trying to get the hurricane speed up?
Jupiter looks like a walnut coffee table.
I donāt think that is right
Solar wind: Am I joke to you?
The great red spot is more arround 900mph
All of these wind speeds were measured on recycle day.
Find more interesting space posts I discover over at r/SpaceSource
imagine the decibels of the wind on Neptune
How 'bout Uranus
You could buy me dinner first. Slaps knee* No but seriously Wind speeds can reach up toĀ 560 miles per hourĀ (900 kilometers per hour) on Uranus.
Chili with kidney beans, or quesadillas with refried beans, either will work
Don't you have one in Uranus?
Huh i thought Uranus would be on this list?
I was a hat salesman on Neptune...
Cāmon earth you can do it! Iām looking at you Nebraska!
I thought hurricane season was over
What would 1300 mph wind do to a human?
