Abstract: The paper presents the results of the modeling of meridional heat and mass transfer in the ocean, computed by the coupled ocean-atmosphere numerical model developed in Max Planck Institute for Meteorology and with the application of the original data assimilation technique. The data on temperature and salinity of the ocean, obtained during the WOCE (The World Ocean Circulation Experiment) in 1991–1995, were used. The paper shows how the data assimilation changes the model characteristics: the ocean current velocities and temperature fields. As the data assimilation method the Generalized Kalman filter (GKF) has been applied.

Keywords: ocean dynamics, model MPI-ESM, data assimilation method GKF.
