There are two types of air masses: COLD AIR AND WARM AIR.Cold Air Masses-Cold air masses can cause thunderstorms and even tornadoes.Warm Air Masses-Warm air masses can bring many hours of steady rain and snow.
I would use the word "polar" to describe an air mass that forms over Alaska. These air masses originate in the Arctic regions and bring cold temperatures and snow to the surrounding areas.
It separates hot air masses and cold air masses

Air masses get their characteristics from where they are made

A cold air mass originates over water or land that is colder than the air temperature at the time. Cold air masses usually originate in the northwest and travel eastward. A warm air mass is formed from warm water or ground temperature that is warmer than the air at the time. Warm air masses usually originate in the southwest and travel east or northeast.
Prevailing winds over Alaska and northern Canada typically carry cold, dry air masses from the north or northwest, originating from the Arctic region. These winds are often associated with high pressure systems that bring clear skies and cold temperatures to the region.
