| Summary: | <!--!introduction!--> The Arctic has experienced dramatic climate changes over recent decades, in which Arctic amplification is the most prominent characteristic with broad influences on climate variability over mid-/low-latitude regions. Previous studies have indicated that Arctic surface warming is simultaneously accompanied by frequent cold winters over Northern Hemisphere mid-latitude continents, forming a "warm Arctic-cold continent" pattern. In addition, other studies suggest a lead-lag seesaw pattern of extreme temperature events with a cold spell over East Asia followed by a warm spell in North America. In this study, we reveal a dipole-like surface air temperature pattern between the Eurasian and North American continents in boreal winter induced by the Arctic sea-ice variability. This surface temperature dipole pattern works on both interannual and decadal time scales. Statistical analyses and atmospheric model experiments demonstrate that the sea-ice retreat over the Barents-Kara Seas can ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
