Eddy energy in the Aleutian Islands region has been low from the fall 2012 through 2018, indicating the likelihood of smaller than average fluxes of volume, heat, salt, and nutrient fluxes through Amukta Pass (p. 49). The chart below plots the average high and low temperature for each month of the year. This feature also encompasses non-stationary systems of both low and high pressure (cyclones and anticyclones) that form and dissipate along fronts and rapidly move in a broad sub-polar band of west-to-east flowing air currents widely known as the prevailing westerlies. The strongest of these storms may make their way to the west coast of North American during the winter and then move across the mid section of the U.S..

Expect 0.7 mm of precipitation over the past 3 hours. “Despite the fact that the Aleutian Archipelago is remote and largely uninhabited, it nonetheless has a long history of predator exploitation, and is also at the front lines of climate change,” said Douglas Rasher. As a storm approaches our area from the west, the wind sets in from the southeast and builds in intensity. Please click on the graph to see a larger version. The Aleutian low is "A region of generally low pressure located near the Aleutian Islands, where sub-polar cyclones reach their maximum intensity. The map shows that the weaker Aleutian Lows (AL) often move into the western Bering Sea. This is also the zone where the colder air from the subarctic meets the warmer moist air to the south. The Aleutian Low shifts position and changes in intensity with the seasons. Their website on "The Cryosphere Today" can be accessed here and it contains the most up-to-date information on ice in the Bering Sea, the Beaufort Sea and other world sea ice areas.

The seasonal changes in surface air tem-perature (SAT) across the Aleutian Islands are relat-ively uniform, from 5 to 10 C in summer to near freezing temperatures in winter. The average temperature difference between July and January is only about 10 degrees F. The moderating influence of the marine environment is the primary reason for this small temperature difference. Expect 7.8 mm of precipitation over the past 3 hours. The average annual temperature for the inhabited islands is about 38 °F in January and 52 °F in August. This means that the Unimak Area is generally free from winter incursions of cold air from the Alaska mainland and only occasionally does cold Siberian area make its way across the Bering Sea to the Aleutian Islands, although in particularly cold winters this does happen.
