atmospheric circulation

Atmospheric circulation refers to the large-scale movement of air around the Earth, driven primarily by the uneven heating of the planet’s surface by the sun. This causes warm air to rise and cool air to sink, creating patterns like trade winds, westerlies, and polar easterlies. These air movements help distribute heat and moisture, influencing weather and climate. They also play a key role in forming pressure systems—highs and lows—which affect precipitation and temperature globally. Understanding atmospheric circulation is vital for predicting weather patterns and climate changes over time.
