然而,我来这里不是为了问木星的大红斑或任何天文问题。这些信息不会成为问题的实际部分,因为上面的信息只是暗示我从哪里得到这个想法。这篇文章只是勾起了我对大气物理学的好奇心。然而,让我们转向真正的问题。在地球上,我们确实有大风暴。不是行星大小的风暴,而是整个国家大小的风暴。 Typhoon Tip, for example, reached more than 2,000 km in diameter. Typhoon Tip also, was an incredibly turbulent environment, with air pockets colliding. Also, lightning and immense winds could have produced immense sound waves that could have scattered atoms away, and heated up the upper atmosphere to scorching temperatures. It's not just restricted to Typhoon Tip, other energetic hurricanes, like Katrina, Patricia etc. were extremely energetic hurricanes that could have produced sound waves and enough turbulence to heat up the upper atmosphere.

Aside from hurricanes, there are also a plethora of extremely turbulent phenomenon on Earth, such as supercells, derechos, squall lines and so on. These environments have a lot of wind shear, fast winds, updrafts and downdrafts, which have a knack for producing intense turbulence. Rain and hailstones colliding with each other, lightning forming, should produce enough sound and turbulence to heat up the upper atmosphere.

Yet this phenomenon does not occur on Earth. Earth's upper atmosphere is really, really cold, excluding the thermosphere, which is indeed scorching hot, but is diffuse and evenly heated, unlike on Jupiter, where storms heat up the areas of the upper atmosphere above them.

Why don't terrestrial storms heat up the upper atmosphere?

The chemical composition at a given level in any planetary atmosphere determines how solar and terrestrial radiation will be "handled." On Earth, the ozone layer in the stratosphere interacts strongly with certain wavelengths of UV radiation, but not IR radiation. On other planets like Jupiter and Venus, there are gaseous compositions at upper levels of the atmospheres that may interact more strongly with IR radiation. Or, as you mentioned, may be heated by friction due to other forms of energy transfer.
