The Circulation in Earth's Atmosphere Is Dominated By

The circulation in Earth's atmosphere is dominated by:

A) a random distribution of transient storms and high-pressure areas, with no permanent overall pattern.
B) one large convection cell in each hemisphere, with air rising at the equator due to solar heating, moving toward the poles at high altitude and returning along the surface.
C) three large convection cells in each hemisphere, with surface winds toward the equator in the tropics and away from the equator at temperate latitudes.
D) bands of winds blowing parallel to the equator, from the east in the tropics and from the west at temperate latitudes.
