prevailing wind
Quick Summary
Prevailing winds are the usual winds in a specific area or region, indicating the dominant wind direction. These winds are a crucial factor in determining and controlling climate and weather patterns.12
Winds are caused by differences in atmospheric pressure. Near the Earth's surface, winds generally flow around areas of high and low pressure, known as anticyclones and cyclones, respectively. In tropical and subtropical regions, trade winds flow westward towards the Equator. In middle latitudes, the westerlies are associated with changeable weather, influenced by migrating cyclones and anticyclones. At higher latitudes, winds are generally easterly near the ground.2
Local winds, such as sea and land breezes or mountain and valley breezes, are also influenced by geographic features and can significantly affect local climate. Wind speeds tend to be strongest during the day due to solar heating, which causes air to overturn.2
