摘要	The summertime anticyclonic circulation mode(SACM) is related to recent substantial loss of sea ice in the Arctic. This review outlines the potential causes of the SACM and considers its influence on sea ice depletion. Local triggers(i.e., sea ice loss and sea surface temperature(SST) variation) and spatiotemporal teleconnections(i.e., extratropical cyclone intrusion, tropical and mid-latitude SST anomalies, and winter atmospheric circulation preconditions) are discussed. The influence of the SACM on the dramatic loss of sea ice is emphasized through inspection of relevant dynamic(i.e., Ekman drift and export) and thermodynamic(i.e., moisture content, cloudiness, and associated changes in radiation) mechanisms. Moreover, the motivation for investigation of the underlying physical mechanisms of the SACM in response to the recent substantial sea ice depletion is also clarified through an attempt to better understand the shifting ice–atmosphere interaction in the Arctic during summer. The record low extent of sea ice in September 2012 could be reset in the near future if the SACM-like scenario continues to exist during summer in the Arctic troposphere.
