Figure 2 clearly indicates that the sea ice extent is
greatly improved by the assimilation run that
assimilates sea ice concentration. We can also observe
that it takes about three months time for the ocean
conditions to adapt to new sea ice extent by the
fluctuations in the sea ice extent during the first three
months. The figure 3 that plots the resulting sea ice
extent after assimilating sea ice thickness denotes
how non-assimilated sea ice variables are enhanced
by the assimilation. Similar results could be observed
from the sea ice velocity analysis as well. However
the sea ice thickness assimilation shows greater
improvement in sea ice extent forecast compared with
the sea ice velocity assimilation.
