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.
Maritime Polar The source region for mP air is over cold ocean currents or high latitude ocean waters. This air does not have the moisture content as mT air. Since mP air is always near saturation, orographic lifting of the air mass can produce widespread rain or snow.This air mass is notorious for producing fog, drizzle, cloudy weather and long lasting light to moderate rain.n the windward side of mountain ranges, mP air can produce an abundance of rain and snow. Once on the lee side of mountains, the mP airmass modifies into a continental airmass. These air masses produce cold fronts but the air is not as cold as polar or arctic fronts.
