At what latitude are the Sub-tropical High Pressure Belts located?

The Sub-tropical High Pressure Belts are located at approximately 30 degrees north and south of the equator. This region is characterized by descending air that creates high pressure, leading to dry and stable atmospheric conditions. The mechanics behind this feature are rooted in the Earth's atmospheric circulation patterns. As warm air rises at the equator, it moves towards the poles at higher altitudes. When this air cools, it descends around the 30-degree latitude marks, leading to the formation of these high-pressure zones.

In contrast, the other options do not align with the established atmospheric models. The area at 10 degrees north and south is typically associated with the Intertropical Convergence Zone (ITCZ), which is a low-pressure belt characterized by rising air and frequent precipitation. The latitudes around 45 degrees north and south are generally associated with the temperate zones and have lower pressure areas, contributing to more dynamic weather patterns. Understanding these distinctions helps reinforce the atmospheric dynamics that shape our planet's climate.
