Simulated 2014 seasonal evolution of mean ice thickness (a), mean floe size (b), and power-law exponent (c), along with NCEP/NCAR reanalysis surface wind speed (d), averaged over all ice-covered areas (with ice concentration greater than 0.15, solid line) and over the MIZ (with ice concentration between 0.15 and 0.8, dotted line) of the whole model domain covering the seas north of 49°N.
