I think Continetial ( I prob spelled it wrong)
cold and dry
Cold, dry air masses that blow into the U.S. from central Canada are known as continental polar (cP) air masses. These air masses are characterized by their low moisture content and cool temperatures, often leading to clear skies and chilly conditions when they move southward. They typically influence weather patterns in the northern U.S. during winter months, bringing cold fronts and sometimes snow. When they interact with warmer, moist air, they can also contribute to the development of storms.
Air masses that form over Canada are usually continental in nature, meaning they are dry and cold, especially in the winter months when they originate from the Arctic region. These air masses tend to bring colder temperatures and clear skies to the regions they move into.
The colliding air masses in Tornado Alley are warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies. This collision is just part of the recipe for tornadoes.
The primary air masses that originate in Canada are continental polar (cP) and maritime polar (mP) air masses. Continental polar air masses develop over the cold land areas, bringing dry and cool conditions, while maritime polar air masses form over the relatively warmer waters of the Pacific and Atlantic Oceans, resulting in moist and cool weather. These air masses can influence weather patterns across North America, particularly during winter months.
Chek
Dry continental air masses. Much of the land is desert with a dry, hot climate.
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.
They come from planet Mars the solar winds blow them onto earth.
