it Turned out that the phenomenon of several reasons. Moreover, different latitudes have different mechanisms.
for example, at low latitudes, near the equator, superprestige atmosphere is maintained by the temperature difference between day and night hemispheres. The thing is, a day on Venus lasts 243 earth days. So the day hemisphere manages to warm up, especially because the planet is much closer to the Sun than the Earth. Besides a thick carbon dioxide atmosphere creates a strong greenhouse effect. Naturally, the gas goes up, which is expanding. And the pressure in it decreases.
a Different picture in the atmosphere over the opposite side of the planet, above the night hemisphere. There are low temperature and high pressure. It is this pressure differential creates a powerful stream of wind which with great speed rushes first to the equator, where the intense heat, and then in the direction of rotation of the planet. And it creates superprestige at low latitudes.
as for the polar and middle latitudes, it can answer nonthermal gas wave, comparable in size to a planet, and large-scale turbulence.
