Weather of Venus
Though many do not realize it, Venus actually has quite a bit of active weather within its atmosphere.
The reason we did not know about such weather is the fact that huge, thick, massive clouds cover the planet.
These clouds are primarily the result of an increased carbon dioxide atmosphere, which is 97% carbon dioxide.
The other 3% is composed of nitrogen and argon.
Because of this atmosphere, the clouds within Venus are purely sulphuric.
The temperature is also increased by the enhanced greenhouse effect that results from this atmosphere.
The sulphuric clouds move quite quickly across Venus. In fact, they can travel as much as three times faster than a hurricane does.
These clouds periodically let sulphuric rain fall, but it evaporates back into the clouds before making it to the ground.
In addition to swift moving clouds, winds are also rapid. At times, they can reach up to 220 mph, but these speeds are not common at all heights.
While winds and clouds move quite quickly near the top of the atmosphere, there are minimal winds near the actual ground of Venus.
This is due to the pressure of the atmosphere, which is estimated to be 92 times the pressure of Earth's.
Another interesting fact is that Venus has been proven to have lightening. Although a controversial subject, the Venus Express confirmed that lightening was indeed present on the planet by finding whistler mode waves; the very source of lightening activity.
While lightening does hit the ground, it is estimated to occur half as frequently as on Earth.
