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.
1 Continental polar (cP): Cold and dry, but not as cold as Arctic air masses. 2  These usually form farther to the south and often dominate the weather picture across the USA during winter. 3  Continental polar masses do form during the summer, but usually influence only the northern USA.ive basic types of air masses determine the USA's weather. They can bring anything from scorching heat to bone-chilling cold depending on the type of air mass. The USA's most violent weather usually occurs in spring when continental polar air clashes with maritime tropical air.
