What is Subpolar?
The belt between 50-70 ° N and S latitudes in the Northern and Southern Hemispheres, adjacent to the Polar Region. Although generally characterized by semi-stationary low-pressure centers such as the Aleutian and Icelandic low-pressure systems, during the winter season, high-pressure areas like the North American and Siberian High can also be seen over large cold land surfaces.
