3.1: Mammatus Clouds Over Mexico


Normal clouds are flat on the bottom. When warm air rises and cool, it usually condenses at a specific temperature and height. An opaque cloud is formed from these water droplets. However, cloud pokets sometimes form with large ice or water droplets. They fall into clear air as they evaporate. These pokets are often assoiated with turbulent or stormy weather at the top of an anvil cloud. The result can be mammatus clouds.
