How does the upper branch of the Hadley cell contribute to the formation of subtropical high pressure belts?
Answer and explanation
Correct answer: Upper air descends near thirty degree latitudes
Option A is correct because air heated near the equator rises and travels poleward in the upper part of the Hadley cell. As it loses heat and moves toward approximately 30° latitude, it descends. This subsidence increases the mass of air over the subtropics and produces high surface pressure. Descending, warming air also suppresses clouds and helps explain the concentration of many major subtropical deserts.
