Numerical Realization of Hybrid Data Assimilation Algorithm in Ensemble Experiments with the MPIESM Coupled Model
Original data assimilation method is considered. This method is applied in conjunction with the coupled Max Planck Institute Earth System Model (MPIESM). The assimilation block and the interface with the MPIESM are realized on the “Lomonosov” supercomputer at the Lomonosov Moscow State University. Several experiments with and without assimilation of the sea level data and temperature-salinity profiles over the Equatorial Atlantic are conducted. The results of these experiments have been analyzed and discussed. In particular, it is shown that the ice concentration in Arctic zone of Russia fits better to the observations then in the reference experiments without assimilation.
