Why don't winds blow directly north and south on the earth?
the heat from the sun does not stay all in one place.
the rotation of the earth curves them to the left and right.
the pattern of air moves from warmer to colder areas.
the axis of the earth tilts some areas away from the sun.

The rotation of the earth curves them to the left and right.

Explanation:

In light of the shape of the earth, the most immediate beams of the sun strike the earth in the region of the equator bringing about the best centralization of warmth, the biggest conceivable measure of radiation, and the greatest warming of the climate here of the earth.

Simultaneously, the sun's beams strike the earth at the shafts at a slanted point, bringing about a much lower centralization of warmth and substantially less radiation so that there is, truth be told, almost no warming of the environment over the posts and thus freezing temperatures.

polar areas, such as antarctica or the south pole.
