The Aleutian Low is a center of atmospheric activity centered over the Aleutian Islands between the east coast of the Siberian Kamchatka Peninsula and the Gulf of Alaska at about 50o N. It is prominent in the winter and disappears in summer, with the average central pressure below 1000 mb in January. This atmospheric activity is a semi-permanent low pressure center. The Aleutian Low is one of the chief centers of action in the atmospheric circulation of the Northern Hemisphere.
