Atmospheric circulation refers to the large-scale movement of air within the Earth's atmosphere. It is driven by various factors, including the uneven heating of the Earth's surface by the Sun, the rotation of the Earth, and the properties of air. The primary circulation patterns in the atmosphere are the global circulation and the smaller-scale weather systems. The global circulation consists of several major cells that span the entire planet, while weather systems are smaller-scale circulations that occur within these larger cells. Global Circulation: 1. Hadley Cell: Near the equator, solar radiation is intense, heating the air and causing it to rise. This creates a region of low pressure and leads to the formation of the Hadley cell. As the air rises, it cools and forms clouds, resulting in abundant rainfall in the tropical regions. The rising air then moves poleward in the upper atmosphere, eventually descending around 30 degrees latitude, creating high-pressure areas and a...
