Continental Polar Air Masses
cold temperatures and little moisture
Those who live in northern portions of the United States expect cold weather during the winter months. These conditions usually result from the invasion of cold arctic air masses that originate from the snow covered regions of northern Canada. Because of the long winter nights and strong radiational cooling found in these regions, the overlying air becomes very cold and very stable. The longer this process continues, the colder the developing air mass becomes, until changing weather patterns transport the arctic air mass southward.

Answer:

Continental polar has very low temperatures, little precipitation, and air pressure varies with the pressure system moving through

The variation in the US continental region is due to the change in the weather during the day and the night.

These are the reasons for the polar air mass:-

Continental Polar air usually forms during the cold period of the year over extensive land areas.

The upper part of the region has a cold breeze while the lower part has a warm breeze.
