Note that the meridional circulation is much lower than the zonal circulation, which transports heat between the day and night sides of the planet. All winds on Venus are ultimately driven by convection. [3] Hot air rises in the equatorial zone, where solar heating is concentrated and flows to the poles.
Re-narrated Horizon episode, first aired in the UK in 1972. [4]We give you a behind-the-scenes look at the making of a nature film.

A NASA spacecraft has captured never-before-seen images of Venus, providing stunning views of the hellishly hot surface of the second rock from the sun. Dark side of Venus revealed in new NASA ...
The main problem with Venus today, from a terraformation standpoint, is the very thick carbon dioxide atmosphere. The ground level pressure of Venus is 9.2 MPa (91 atm; 1,330 psi). This also, through the greenhouse effect, causes the temperature on the surface to be several hundred degrees too hot for any significant organisms.
Venus and Mercury have long nights because of their slow rotational periods. [30] The planet Venus rotates once every 243 Earth days. [31] Because of its unusual retrograde rotation, nights last 116.75 Earth days. [32] The dense greenhouse atmosphere on Venus keeps its surface hot enough to melt lead throughout the night.
