Evolution of sea ice and atmospheric conditions during winter-to-spring transition. The evolution of (a) open water fraction, (b) wind speed, (c) air temperature and (d) the distance from clusters to the nearest ice edge during winter-to-spring transition. In panel (a), the solid lines and closed circles are the open water fractions derived from AMSR-2 and TS-X data, respectively, at each cluster. In panel (b), solid lines are the wind speeds from ERA interim data at each cluster. In panel (c), solid lines are the air temperatures from AWS at each cluster (air temperature data from C2 are not shown here). In all panels, black, blue, red and green colors represent C1, C2, C3 and C4, respectively. Wind events (such as w1, w2…) are marked in the plots. DOI: https://doi.org/10.1525/elementa.232.f3
