Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold. Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable. These air masses originate over northern Canada and Alaska as a result of radiational cooling. They move southward, east of Rockies into the Plains, then eastward.
Air Masses. The air masses in and around North America include the continental arctic (cA), maritime polar (mP), maritime tropical (mT), continental tropical (cT), and continental polar (cP) air masses. Credit: NOAA. Air is not the same everywhere.In North America, for example, cold and dry air covering thousands of miles flows south from the Arctic, especially in winter, and warm moist air flows south from the Gulf of Mexico.These different types air are called air masses.he word that describes humidity (maritime or continental) is paired with the word that describes temperature (equatorial, tropical, polar or arctic). For example, if an air mass forms over a tropical ocean, it is called maritime tropical.
