Wind patterns are the movement of air across the Earth's surface, influenced by factors like temperature, pressure, and the rotation of the planet. Warm air rises, creating areas of low pressure, while cooler air sinks, leading to high-pressure zones. This difference causes air to flow from high to low pressure, resulting in winds that can vary in speed and direction. These wind patterns are essential for weather systems and climate. For example, the Trade Winds blow from east to west in the tropics, while the Jet Stream is a fast-flowing air current high in the atmosphere that influences weather patterns across continents.
