Characteristics of Air Masses

The video explains the concept of airmasses, which are large bodies of air with similar temperature and humidity. It introduces four primary types of airmasses: maritime tropical, maritime polar, continental tropical, and continental polar. Maritime tropical airmasses are warm and humid, forming over warm ocean waters. Maritime polar airmasses are cold and wet, forming over cold ocean waters. Continental tropical airmasses are hot and dry, forming over land in warm regions. Continental polar airmasses are cold and dry, forming over land in cold regions. These airmasses influence weather patterns, especially in the United States.
