Quizplus · Accepted Answer

The sinking air of the subtropical highs is responsible for the formation of deserts found at 30N and 30S latitudes. Due to the Hadley Cell circulation, warm air rises at the equator and moves towards the poles. As it moves away from the equator, it cools and sinks back to the surface at around 30N and 30S latitudes, creating high-pressure zones known as subtropical highs. These high-pressure zones result in stable atmospheric conditions, little to no precipitation, and hence desert regions.
