.
What is the primary function of Polar cells in the Earth's atmospheric circulation?

transport warm air from the Equator to the poles

increase humidity in tropical regions

move cold air from the poles toward lower latitudes

create high-pressure systems at the Equator

Move cold air from the poles toward lower latitudes.

Polar cells circulate cold polar air equatorward near the surface and rising air near ~60° latitude, transporting cold air away from the poles.
