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
Air masses build over source regions that have relatively similar ground surface characteristics. Air masses that build over the land are called continental air masses while air masses that build over the open ocean are called maritime air masses. Air masses cover 100 s to 1000 s of kilometers of distance. What causes these huge regions of air to move? Air masses build when the air stagnates over a region for several days/weeks. To move these huge regions of air, the weather pattern needs to change to allow the air mass to move. One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream.
