| Session Description | The accelerated warming Arctic outpacing the global warming, known as Arctic amplification (AA), has profound impacts on not just the Arctic, but mid-latitude weather and climate. Recent years have seen reductions in sea-ice extent and snow cover over land, as well as a noticeable increase in the amplitude and wavelength of atmospheric short waves around the midlatitude, which was particularly suggested as a consequence of the accelerated warming Arctic and source of mid-latitude weather and climate extremes. Another interesting note is that mid-latitude has experienced rather cold winters, known as “warm Arctic, cold continent” pattern. Because of these reasons, most studies analyzing the Arctic linkage to mid-latitude weather and climate have focused on winter season. The extent to which the AA affects the mid-latitude circulation and contributes to the observed increases in weather and climate extremes has been a subject of active research. The goal of this session is to identify knowledge gaps, to suggest future research lines for advancement, and to discuss possible risks for society. |
