What is the temperature of continental polar?

Continental polar (cP) air masses are generally characterized by cool to cold temperatures. The temperature of continental polar air typically ranges from about -10°C to 10°C (14°F to 50°F). These air masses form over land in high-latitude regions, such as northern Canada and Siberia, where they originate from cold, dry regions.

As they move southward, the cP air masses can modify slightly through mixing with warmer air, especially in the lower altitudes; however, they generally remain much colder than surrounding air masses. The characteristics of continental polar air contribute to the cold weather experienced in regions affected by these air masses, particularly during winter months when they are more prevalent.
