Marine Time Polar Air Mass

Another air mass that we have is known as “marine time polar air”. This type of air is known for its cool and moist environment. The best location in the United States to find this air mass is in the Gulf of Alaska. Due to its high moisture content it tends to create a higher amount of precipitation in the region of Southern Alaska. This air mass at times can send increased moisture into the Pacific Northwest of the United States. The temps with this air mass are not as cold as its counter-part, Continental Polar air mass. This is due to the fact that it is over the water which keeps the temps a tad bit warmer. This air mass is the strongest in the winter months and is also represented by Low pressure. Due to having low pressure associated with this air mass it creates an unstable atmosphere which leads to enhanced precipitation chances throughout the Gulf of Alaska and the Pacific Northwest.
