The belt of light and variable winds between the westerly wind belt and the northeast trade winds is called the _______________.

A polar frontal zone
B doldrum belt
C intertropical convergence zone
D subtropical high pressure belt
AI Explanation

The correct answer is C) intertropical convergence zone. The intertropical convergence zone (ITCZ) is the belt of light and variable winds located between the westerly wind belt and the northeast trade winds. This zone is characterized by the convergence of air masses from the northern and southern hemispheres, resulting in low pressure and calm, variable winds. The other options are incorrect because: A) The polar frontal zone is the boundary between cold polar air and warmer subtropical air, not the belt of light and variable winds. B) The doldrums refer to the same ITCZ region, but "doldrum belt" is not the standard term. D) The subtropical high-pressure belt is a different atmospheric feature, located poleward of the ITCZ.
