摘要：The recent accelerated Arctic sea ice decline has been proposed as a possible forcing factor for mid-latitude circulation changes, which can be projected onto the Arctic Oscillation/North Atlantic Oscillation (AO/NAO) mode. However, the timing and physical mechanisms linking AO responses to the Arctic sea ice forcing are not entirely understood. In this study, we suggest the connection between November Barents and Kara sea ice extent and the following winter’s atmospheric circulation, in terms of the fast sea ice retreat and the subsequent modification of local air-sea heat fluxes. In particular, we explore the dynamical processes that link November sea ice in the Barents and Kara Seas with the development of AO anomalies in February.
