polar air mass (meteorology), air mass that forms over land or water in the higher latitudes.
over northern Canada and Alaska
The boundary between cold and warm air masses is called a front. Fronts typically form where two air masses with different temperatures, humidity levels, and densities meet. This transition zone can result in weather changes such as clouds, precipitation, and temperature shifts.
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.
Extratropical cyclones typically form along the boundaries between cold and warm air masses in the mid-latitudes. These cyclones are characterized by a mix of warm and cold air, and they often develop over the oceans before moving toward land. Extratropical cyclones can bring significant weather changes, including strong winds, heavy rain, and sometimes snow.
Pay close attention to your question. A maritime (meaning oceanic) air mass has moisture, therefore it's not dry. Polar (meaning from the polar region) air mass is cold, therefore it is cold. Hence a maritime polar air mass would be moist and cold...how hard was that?

continental air masses
Continental polar air masses form over cold, dry land areas near the poles, such as Siberia in Asia and northern Canada in North America. These air masses are responsible for bringing cold temperatures and dry weather when they move southward.
Hurricanes form in warm tropical waters and the conditions aren't right in higher northern latitudes because the temperature of the water is cold.
The point where these two air masses meet is called a front.If cold air advances and pushes away the warm air, it forms a cold front.When warm air advances, it rides up over the denser, cold air mass to form a warm front.If neither air mass advances, it forms a stationary front.
A type of storm that occurs when warm and cold air masses collide is called a frontal storm. As the warm air rises over the cold air, it cools and condenses to form clouds and precipitation. This collision of air masses often leads to the development of thunderstorms or even more severe weather events like tornadoes.
