Aleutian Low
Extratropical cyclones which form in the sub-polar latitudes in the North Pacific typically slow down and reach maximum intensity in the area of the Aleutian Low.The low serves as an atmospheric driver for low-pressure systems, post-tropical cyclones and their remnants and can generate strong storms that impact Alaska and Canada.The circulation pattern is measured based on averages of synoptic features help mark the locations of cyclones and their paths over a given time period.The circulation pattern shifts during the Northern Hemisphere summer when the North Pacific High takes over and breaks apart the Aleutian Low.The strength of the Aleutian Low has been proposed as a driving factor in determining primary production in the water column and, in turn, impacting the catch in the salmon fishery.
