Which term describes the belt of deserts and dry air around 30 degrees latitude, where Sahara is located?

Explanation:
Around 30° latitude, air tends to descend in a subtropical high-pressure belt, warming as it sinks and reducing humidity, which limits rainfall and creates desert climates like the Sahara. This belt is historically called the horse latitudes—the calm, dry zone sailors encountered there. The larger circulation that produces this pattern is the Hadley cell, which explains why dry air sinks at these latitudes; the Intertropical Convergence Zone sits near the equator with frequent rain, and a front is simply a boundary between air masses, not a global dry belt. So the term that best describes this dry, desert belt at about 30° is horse latitudes.
