The model result presented by Timmermann et al. ( 2012 ) is not realistic in the
Amundsen Sea, showing a bottom potential temperature of
C with almost
no CDW intrusion (Fig. 2 ). Although Timmermann et al. ( 2012 ) suggest that NCEP
reanalysis forcing is the reason for the cold Amundsen Sea condition, the simula-
tion with ERA-interim forcing cannot reproduce the CDW intrusion either, indi-
cating that the forcing is not the only reason for the cold conditions on the
Amundsen Sea continental shelf in FESOM.
The reason for the dif
