Quizplus · Accepted Answer

In the tropics, the pressure rises and falls twice a day due to the daily cycle of heating and cooling. As the sun rises and warms the air, the pressure decreases, and as the sun sets and the air cools, the pressure increases. This regular pattern is known as the diurnal pressure cycle.
