Detailed explanation-1: -In each hemisphere there are three cells (Hadley cell, Ferrel cell and Polar cell) in which air circulates through the entire depth of the troposphere. The troposphere is the name given to the vertical extent of the atmosphere from the surface, right up to between 10 and 15 km high.

Detailed explanation-2: -Answer and Explanation: There are six atmospheric circulation cells because the Coriolis effect causes the air in the circulation cell to curve, moving clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

Detailed explanation-3: -The atmosphere has six major convection cells, three in the northern hemisphere and three in the southern. Coriolis effect results in there being three convection cells per hemisphere rather than one. Winds blow at the base of the atmospheric convection cells.

Detailed explanation-4: -Answer and Explanation: The Earth has three primary atmospheric circulation cells as a result of the Coriolis effect. As air moves toward the equator, the rotation of the Earth causes it to curve to the west. This slows its progression toward the equator and the air warms, rises, and head away from the equator.
