Air mass. In meteorology, an air mass is a volume of air defined by its temperature and water vapor content. Air masses cover many hundreds or thousands of square miles, and adapt to the characteristics of the surface below them. They are classified according to latitude and their continental or maritime source regions. Colder air masses are termed polar or arctic, while warmer air masses are deemed tropical. Continental and superior air masses are dry while maritime and monsoon air masses are moist. Weat
a warm air mass is caught between two colder air masses. The colder air moves under the warmer air pushing it up and then moves forward until it meets a mass that is warmer and pushes it up too.
