The circulation pattern in Venus's atmosphere consists of:

A) one main convection cell in each of the northern and southern hemispheres, which extends from the equator almost to the poles and drives weaker cells above and below it.
B) three cells in each of the northern and southern hemispheres, resulting from upwelling at the equator combined with the Coriolis force due to the planet's rotation.
C) one main convection cell extending across the equator from near the pole in the "summer" hemisphere to subtropical latitudes in the "winter" hemisphere.
D) several individual convection cells in regions where the time of day is noon to late afternoon, moving around the planet to keep pace with the Sun as Venus rotates.
