Atmospheric Pressure (or barometric pressure) is the force per unit area exerted by the above body of air (or atmospheric column). The Aleutian Low is the average sea level pressure in the region of Aleutian Islands and is one of the main centers of storm activity in the Northern Hemisphere (Huschke, R.E, 1980)
