on summer Arctic sea ice extent
[1] Based on a statistical analysis incorporating 925‐hPa wind fields from the NCEP/NCAR Reanalyses, it is shown that the combined effect of winter and summer wind forcing accounts for 50 % of the variance of the change in September Arctic sea ice extent from one year to the next (DSIE) and it also...
