Are they "the sort of tycoons". ? ?

Do you mean "typhoons"?

no sir. i have read about this one at one place, that on neptune and on the jupiter, the looking spots are the typhoons, so is it correct?

Hi Sunil,
You are asking about the 'Great Red Spot' on Jupiter, and the 'Great Dark Spot' on Neptune, is that right?
Both have been described as very large persistent circular storms - I've not heard them described as 'typhoons' or 'hurricanes', or even as 'cyclones', but any of those labels might be applied by somebody without too much argument ...

Yes, they are large weather systems that rotate much like hurricanes or typhoons.

You would get some argument from me.

The Great Red Spot is a high-pressure system, associated with atmospheric subsidence, whereas typhoons/hurricanes are low-pressure systems, associated with atmospheric uplift.

The winds associated with both these systems (Great Red and Dark spots) flow outward from the center.

Some confusion probably comes from the counter-clockwise circulation. Most people see hurricanes or typhoons in the northern hemisphere, where they rotate (due to the coriolis "force") counter-clockwise. But in the southern hemisphere, the circulation directions are reversed. Since the Great Red Spot is in Jupiter's southern hemisphere, it rotates counter-clockwise. I believe Neptune's Dark Spot is in the southern hemisphere as well.

Whatever their nature, the spots are indeed weather patterns.

so wind is present there?

thanks cross for tripple claps, cran has identified correctly that what i actually want to say, thanks cran. and they are comparable least in speed of rotation to the axis? if jupiter has a mass hydrogen base then why not it looks more brightened 'not exactly like sun'. and when the comet was struck with the surface of jupiter, why not the total hydrogen which was present on the surface explodes into flame?
thank u christhoph for your reply.

sunil

The hydrogen did not explode into flames because there was no oxygen there.

Yes Sunil, the great spots are remarkably stable and seem to be linked with the planets' rotations ... smaller vortices or 'storms' (at least on Jupiter) seem to be more closely linked with the atmospheric belts (winds) which vary according to latitude (faster at the equator) ... over time the smaller storms can merge or pass each other ...

And Kaptain K is pretty close to the mark - for something to 'burn', it needs free oxygen ... or it needs a sustained nuclear reaction to liberate energy (as heat and light, etc)... Jupiter doesn't have enough mass to initiate a nuclear reaction, so its internal heat (which may be the cause of the 'redness' of the Great Red Spot) from pressure and friction, is much less than that of the sun...

Jupiter is not massive enough to make fusion in its core. For it to burn like the sun, it would take 1000x the mass it currently has.

oh, nice cross.
i was thinking that jupiter may become the prospective energy provider in the solar system as an alternate one.
if the fusion process started there on by providing the source through the sattelite struck on it so is it possible to get the result !

sunil

I believe that it is not possible to get fusion generated from Jupiter.



Jupiter actually does radiate "heat" It is of very low frequency. This little bit would not be enough for earth however.

Well, Jupiter's Great Red Spot and Neptune's Great Dark Spot can be considered hurricanes. Winds in Jupiter's GRS are over 230 mph, possibly near 300 mph. Neptune has the most violent weather in the solar system, and is the windiest as well. Winds there have been clocked at 1,250 mph. When one of the Voyager probes measured winds inside its GDS, they were around 1,500 mph-the highest wind measurment of any planet in our solar system. Note that this is twice the speed of sound.

What would it be like to gaze at that thing up close?!?

Again, I'd have to disagree. Using the term hurricanes implies that the same atmospheric mechanism that drives tropical cyclones on Earth, drives the Spots on these planets. These large storms on Jupiter and Neptune are not areas of low pressure. They are areas of HIGH pressure. I don't know the proposed mechanism for such strong and persistent high pressure systems, but calling them hurricanes is misleading.

yaa, ferro, the sky view of the hurricane scatter here and there, but the spots appears on neptune and jupiter seem to be steady though they are rotating at the place, it means they must not be the spots of hurricane.
