WebJan 13, 2012 · Arctic sea ice extent at the end of the 2011 melt season was far below average. Credit: NASA. That explains the snow, but not the cold. Last winter, however, I wrote several stories about a tantalizing explanation for the snow and cold, which I called the “Arctic Paradox.” In short, it holds that as the Arctic warms up — it's generally ... WebJun 10, 2024 · Introduction Cold surges (CSs), characterized by a steep temperature drop within one or two days, are energetic systems associated with the East Asian winter monsoon (EAWM). Northerly winds bring cold air from high-latitude regions into East Asia, leading to an abrupt drop in local temperature.

WebJul 25, 2024 · During the strong EAWM phase, the East Asian trough deepens, the East Asian jet stream strengthens, whereas the Siberian High amplifies and expands toward East Asia. This atmospheric circulation pattern enhances the cold northerly wind toward East Asia, eventually bringing cold conditions over East Asia [ 11, 12, 13, 14, 15 ]. WebJet streams are the product of two factors: the atmospheric heating by solar radiation that produces the large-scale polar, Ferrel, and Hadley circulation cells, and the action of the Coriolis force acting on those moving masses. The Coriolis force is caused by the planet's rotation on its axis. inband ip address
