Christoforou believes that the so-called Aleutian Low _ a large, semi-stable low-pressure cell southwest of Alaska _ tends to move west at solar maximum and east at solar minimum.

On December 15, the Aleutian Low opened up a large atmospheric river ( the Pineapple Express ) again, over California, which fed the storm system moisture, allowing it to strengthen significantly.

"You'll be in the tailing end of a big storm center called the Aleutian Low, " he said, which resides in that part of the Pacific from October through much of April.

The existence of such transients are also closely related to the formation of the Icelandic and Aleutian Low the two most prominent general circulation features in the mid-to sub-polar northern latitudes.

In the more maritime and generally wetter Russian Far East, Kamchatka, exposed during winter to moisture from the Aleutian Low, has much more extensive glaciation totaling around with 448 known glaciers as of 2010.

The Aleutian Low also makes the sunshine hours the lowest of Japan's major population centres and in the winter the wind speeds are the highest in Japan with an average of, which adds to the cold of a typical winter day.

At inter-annual time scales the PDO index is reconstructed as the sum of random and ENSO induced variability in the Aleutian low, whereas on decadal timescales ENSO teleconnections, stochastic atmospheric forcing and changes in the North Pacific oceanic gyre circulation contribute approximately equally.

Rainfall is however less heavy than in most parts of mainland Japan since the island is too far south to be influenced by the Aleutian Low and too far from mainland Asia to receive monsoonal rainfall or orographic precipitation on the equatorward side of the Siberian High.

The propagation of h anomalies in the western pacific changes the KOE axis and strength suggest that Rossby waves excited by the Aleutian low propagate the PDO signal from the North Pacific to the KOE through changes in the KOE axis while Rossby waves associated with the NPO propagate the North Pacific Gyre oscillation signal through changes in the KOE strength.
