Continental Polar (cP) air masses are cold, dry air masses that form over land in polar regions. They typically originate in areas like northern Canada and Alaska, where the ground is covered in snow and ice. These air masses are characterized by low humidity and stable conditions, leading to clear skies and cool temperatures. When Continental Polar air moves southward, it can influence weather patterns, especially during winter. It often brings cold temperatures to regions it affects, such as the northern United States. This air mass can also interact with warmer, moist air, potentially leading to the formation of clouds and precipitation.
