Q: What is an air depression?

It is mentioned that a certain region is under the influence of an atmospheric depression when the atmospheric pressure decreases from the neighboring regions, and the pressure drop coincides with lighter air, so it rises to the upper layers of the atmosphere, and revolves around the center of the depression in a counterclockwise direction (in the northern hemisphere), and when The air rises and cools, its content of water vapor condenses, forming clouds, and the depression causes certain atmospheric changes to the area it affects, such as: precipitation, strong winds, and a decrease in temperatures.
