Question

Quizplus · Accepted Answer

The shifts in the dry and wet seasons of the tropics are mainly caused by the movement of the Intertropical Convergence Zone (ITCZ). The ITCZ is a region of low pressure near the Earth's Equator where the northeast and southeast trade winds converge. As the ITCZ moves north and south with the seasons, it brings with it the wet and dry seasons to different regions of the tropics.
