説明
The response of winter (November–April) sea-ice motions to winds between 2003 and 2012 showed large year to year variations in the southern Canada Basin and the region along the Transpolar Drift Stream. We introduced the anomalies of the areal mean of sea-ice velocity curls averaged for the southern Canada Basin as a proxy of the intensity of the clockwise sea-ice motion in the basin. The composite analysis based on the sea-ice velocity curls showed that the clockwise motion was enhanced when the sea-ice motions in the Alaskan coastal region increased with less sea-ice concentration and the along-shore wind in November–December.
