Role of atmospheric factors in forcing Arctic sea ice variability
The spatial structure of the Arctic sea ice concentration(SIC)variability and the connection to atmospheric as well as radiative forcing during winter and summer for the 1979-2017 period are investigated.The interannual variability with different spatial characteristics of SIC in summer and winter i...
