英文摘要: The impacts of Arctic summer wind on ice-ocean heat processes in the sea ice reduction zone were investigated using a pan-Arctic ice-ocean model. The interannual simulation demonstrated event-like sea ice melting because of enhanced solar radiation input and upward ocean heat transfer in the Canada Basin area. Both factors were derived from mechanical ice divergence under cyclonic wind stress. Atmospheric heat penetration into the newly formed open leads was estimated to be a primary contributor to sea ice lateral/bottom melting. The vertical ocean heat flux associated with wind-driven upwelling/mixing was the secondary factor on a monthly time scale. The modeled interannual variability indicated that the relative role of internal ocean dynamics in sea ice variability was greater under cyclonic wind patterns compared with anticyclonic wind conditions. Key Points Wind-driven ice-ocean heat processes with upwelling/mixing events are addressed. Interannual variability in ocean heat balance is quantitatively addressed. Possible scenario on a record minimum extent of Arctic sea ice is proposed. ©2013. American Geophysical Union. All Rights Reserved.
