Аннотация: Estimates of the meridional mass flow in the Antarctic bottom water, calculated from the coupled Earth-Earth-atmosphere model, MPI-ESM and using original methods of observational data assimilation are presented. For the assimilation data were acquired of latitudinal CTD temperature and salinity profiles in 1991-1995 taken from the World Ocean Circulation Experiment WOCE. Estimates of the velocities of the Antarctic bottom water currents as purely model (control) and with the assimilation of observational data are given. The assimilation method previously called as the generalized Kalman Filter (GKF), was used, which coincides in a particular case with the classical Kalman method (EnKF). It is shown that the model calculations are close to estimates of the geostrophic flow transfer based on the dynamic method.
