Maritime polar air masses.
A maritime polar air mass would form over the northern Atlantic Ocean due to its maritime location and cold temperatures. This air mass would be cool, moist, and unstable, bringing cloudy conditions and precipitation to nearby coastal areas.
Continental polar air masses originate over cold, dry regions in the northern hemisphere, such as northern Canada and Siberia. These air masses form when cold air masses move southward from the polar regions and become isolated over land, leading to cooling and drying.
Continental tropical air masses form where their name suggests: over land in regions in the tropics (up to about 25° from the equator). In North America, this occurs in northern Mexico. The air masses are characterized by clear skies and negligible rainfall. If one moves northeast into the Great Plains and stagnates, a severe drought can result.

A blizzard is most likely to form in regions with cold temperatures and strong winds, such as polar regions or areas with cold air masses colliding with warmer air masses. Common areas for blizzards include the Northern United States, Canada, Northern Europe, and parts of Russia and Asia.

Over Northern Canada , North Pacific Ocean , and North Atlantic Ocean.
A maritime polar air mass would likely form over the northern Atlantic Ocean due to the cold ocean waters affecting the air temperature and humidity. This type of air mass is characterized by being cold and moist, bringing precipitation and possibly storms to neighboring regions.
Continental polar air masses originate over cold, dry regions in the northern hemisphere, such as northern Canada and Siberia. These air masses form when cold air masses move southward from the polar regions and become isolated over land, leading to cooling and drying.
