Aleutian low

American  

[uh-loo-shuhn loh] / əˈlu ʃən ˈloʊ /

noun

Meteorology.

1. a semipermanent, subarctic system of low atmospheric pressure in the Gulf of Alaska, near the Aleutian Islands, a storm-breeding area from late fall into late spring, as migratory lows often reach maximum intensity there: as the Aleutian low becomes weakened and displaced toward the North Pole with the onset of summer, the North Pacific high becomes more dominant.
