The Hadley Cell is a large-scale atmospheric circulation pattern that occurs in tropical regions. It is characterized by warm air rising near the equator, which then cools and descends around 30 degrees latitude in both hemispheres. This process creates trade winds that blow from east to west and contributes to the formation of deserts in these subtropical regions. The Hadley Cell plays a crucial role in global climate and weather patterns. It influences precipitation distribution, leading to wet conditions near the equator and dry conditions in the subtropics. Understanding the Hadley Cell helps scientists predict weather and climate changes, impacting ecosystems and human activities.
