Abstract
To investigate interaction and feedback mechanisms of different climate components in the Arctic, we use a regional atmosphere-ocean model setup, consisting of the global ocean - sea-ice model MPIOM with high resolution in the Arctic coupled to the regional atmosphere model REMO. We perform an experiment using reanalysis data from the European Center of Medium Range Weather Forecast (ERA-40) as external forcing to simulate the climate of the last decades (1958-2001). We analyze this experiment in order to improve our understanding of ocean - sea-ice - atmosphere processes at the marginal ice zone in the Greenland-Iceland-Norwegian (GIN) Sea. We present first results on the variability of the marginal ice zone in GIN Sea, where in the last century the commonly named Arctic Odden has been observed frequently, an ice tongue with large daily variability in size and shape. We are interested in the dynamics of the formation of such a sea-ice tongue and show that in our model advection of ice rather than new ice formation is the driving mechanism.
