What 2 global belts explain the climate of Sahara?

1. The Intertropical Convergence Zone (ITCZ): The ITCZ is a low-pressure zone that encircles the Earth near the equator. It is characterized by rising air that leads to cloud formation and precipitation. The position of the ITCZ shifts seasonally, following the sun's path. During the summer, the ITCZ is located over the Sahara, bringing rainfall to the region. However, during the winter, the ITCZ moves south, leaving the Sahara dry.

2. The subtropical high-pressure belt: The subtropical high-pressure belt is a zone of high atmospheric pressure located around 30 degrees north and south of the equator. Air in this belt sinks and warms, leading to clear skies and dry conditions. The subtropical high-pressure belt is responsible for the dry conditions in the Sahara during the winter.
