Abstract—A scheme of a periodic assimilation of climatic temperature and salinity data into a model is pro-
posed. In accordance with the criteria chosen on the basis of numerical experiments, an optimum assimilation
period of three hours is set. The proposed method allows a hydrodynamic adaptation of the fields of tempera-
ture, salinity, and flow velocity that are close to the climatic ones within the framework of the proposed criteria.
The main feature of the adapted fields of vertical flows in the layer 0–700 m is their smooth character and an
almost complete absence of small-scale noise. The extreme values of vertical velocity in this layer decrease
byalmost an order of magnitude as compared to analogous values calculated for the variant of data assimilation
with a weak adjustment of fields.
