Arctic-associated increased fluctuations of midlatitude winter temperature in the 1.5° and 2.0° warmer world
Abstract In recent decades, the interior regions of Eurasia and North America have experienced several unprecedentedly cold winters despite the global surface air temperature increases. One possible explanation of these increasing extreme cold winters comes from the so-called Warm Arctic Cold Contin...
