[ACG38-12] Robust estimation of Arctic sea-ice loss impact on Eurasian cooling
Keywords:sea ice, Arctic, cold winter
In this research, we successfully detected a signature of Eurasian cooling excited by sea-ice decline in the Barents-Kara Sea, by generating a four kind of historical large ensemble simulation based on atmospheric general circulation model (AGCM), and also by using historical large ensemble of 6 different AGCM. We will conclude that a certain part of the Eurasian cooling trend has been driven by sea-ice loss, but the sea-ice forced effect may be underestimated in the AGCM than real.
