Answer:
Without seeing the image of the air mass, it is difficult to determine the exact type of air mass that is moving south from Canada into the United States. However, based on the general principles of air masses, we can make an educated guess.
In general, when a cold air mass moves into an area, it is likely to be a continental polar (cP) air mass. A continental polar air mass is characterized by cold and dry air that forms over land in high latitudes. It is typically stable and brings clear skies and cold temperatures.
So, it is possible that a continental polar air mass is moving south from Canada into the United States. However, other types of air masses could also be involved, depending on the specific weather patterns and atmospheric conditions in the region.
