What is circulation of the atmosphere?

The circulation of the atmosphere refers to the large-scale movement of air masses, driven primarily by solar heating and the Earth's rotation. It includes global wind patterns, such as trade winds, westerlies, and polar easterlies, which redistribute heat and moisture around the planet. This circulation plays a crucial role in determining climate and weather patterns, influencing everything from ocean currents to precipitation. Overall, it helps maintain the balance of energy within the Earth's climate system.
