An area of low air pressure that causes storms is called a cyclone. Cyclones develop when warm, moist air rises and creates a low-pressure zone, leading to the formation of clouds and precipitation. They can occur in various forms, including tropical cyclones, which form over warm ocean waters and can lead to severe weather events like hurricanes and typhoons. Cyclones are characterized by intense winds, heavy rainfall, and can result in significant impact on coastal regions and communities. Meteorologists track cyclones to warn and prepare affected areas for potential storms.
