Global winds are large-scale air movements that occur in the Earth's atmosphere. They are primarily driven by the uneven heating of the Earth's surface by the Sun. Warm air rises near the equator, creating low-pressure areas, while cooler air sinks at the poles, resulting in high-pressure zones. This difference in pressure causes air to flow from high to low-pressure areas, creating wind patterns. These winds are categorized into three main types: trade winds, westerlies, and polar easterlies. Trade winds blow from east to west in the tropics, while westerlies blow from west to east in the mid-latitudes. Polar easterlies flow from east to west near the poles. Together, these winds play a crucial role in regulating the Earth's climate and weather patterns.
