A Continental Polar Air Mass is a type of air mass that forms over land in polar regions, characterized by cold and dry conditions. These air masses typically originate from areas like northern Canada or Siberia, where the surface is covered with snow and ice. As a result, they bring cool temperatures and low humidity when they move southward. When a Continental Polar Air Mass interacts with warmer air masses, it can lead to the development of weather systems, such as cold fronts. These fronts can cause clear skies and stable weather, but they may also bring chilly temperatures and frost in the regions they affect.
