Aleutian Low The low pressure center located near the Aleutian Islands on mean charts of sea level pressure during the winter. It represents one of the main centers of action in the atmospheric circulation of the Northern Hemisphere.
Aleutian Low: A semi-permanent, atmospheric low pressure centre located near the Aleutian Islands on charts of mean sea-level pressure. It is most intense in the winter.
Aleutian Low - A large cell of low' pressure centered over the Aleutian Islands of the North Pacific during the winter.
Altimeter - An aneroid barometer calibrated to indicate altitude instead of pressure.
Aleutian low The subpolar low-pressure area that is centered near the Aleutian Islands on charts that show mean sea level pressure.
ALEUTIAN LOW
A semi-permanent, subpolar area of low pressure located in the Gulf of Alaska near the Aleutian Islands. It is a generating area for storms and migratory lows often reach maximum intensity in this area.
The Aleutian low, low pressure centre located at about 50°N over the Aleutian islands.
It is strongest in the Northern Hemispheric summer and is displaced towards the equator during the winter when the Aleutian Low becomes more dominate. Comparable systems are the Azores High and the Bermuda High.
Kona is the Polynesian word for "leeward." It is associated with a southward or a southeastward swing of the Aleutian low and the passage of a secondary depression (kona cyclone) from northwest to southeast, north of the islands.
A semi-permanent, subtropical area of high pressure in the North Pacific Ocean. It is strongest in the Northern Hemispheric summer and is displaced towards the equator during the winter when the Aleutian Low becomes more dominate.
They are not of a transitory nature, like migratory lows that develop from temperature and density differences. Related terms: Icelandic Low, Aleutian Low, North Pacific High, Siberian High, and Bermuda High ...
Subpolar low High-latitude, semipermanent cyclones marking the convergence of planetary-scale surface southwesterlies of midlatitudes with surface northeasterlies of polar latitudes; Icelandic low and Aleutian low are examples. ...
In the winter, a strong Siberian high, with pressures above 1035 mb, and a high in the western U.S., the Intermountain High, form. The winter Aleutian low in the Pacific is another customary feature, with pressures below 1000 mb, ...
affecting climate from New England to western Europe as far eastward as central Siberia and eastern Mediterranean and southward to West Africa.

This is often related to the deeper than normal Aleutian low, a split jet-level flow over the western U.S. and a trough in the southeastern U.S.. This pattern is called the "Pacific North American Teleconnection pattern".
