- Аннотация: The joint ocean-Earth-atmosphere model of the Max Planck Institute forMeteorology with application of original data assimilation methods are used to estimate the meridional heat and mass flows.The CTD-sections of temperature and salinity across the Atlantic Ocean for1991—1995 obtained in the course of the WOCE (The World Ocean Circulation Experi-ment) international experiment areused as observationdata. The sections contain about 650 stations;each of them provides from 100 to3000 measurements from the sea surface to the bottom. In our studyboth the control estimates for the velocities of currents and those with assimilation of the data of these experiments areobtained. Using visualization facilities,we have shown how data assimilation changes the model characteristics, including velocities of currents and temperature fields at different sea levels. The graphs demonstrate the influence of the change in the initial field after data assimilation on the results of the model calculations after 6 and 11 months of integration for both the observed model characteristics and those which are not observed directly.The Generalized Kalman Filter (GKF) method which coin-cides in a particular case with the classical Ensemble Kalman Filter (EnKF) is used as the data assimilation method. The results of calculations of the heat and mass flowsareanalyzed and compared with thoseof control calculations with no data assimilation.The calculations wereperformed on the supercomputers ―Mistral‖inDKRZ (Deutsches Klimarechenzentrum, Hamburg, Germany) and ―Lomonosov-2‖in the Lomonosov Moscow State University.
