Analysis of Observed Results and Methods of Calculation of Hydrophysical Fields in the Ocean


Based on mean multiyear temperature and salinity data structural zones and layers are isolated. Within their limits there are favourable conditions for the development of processes such as layer convection and salt fingers. It is shown that distribution of their parameters is conditioned by location of intermediate water mass boundaries and front interfaces. Stability of the density ratio valueRϱ for various areas is revealed. The obtained results are in good agreement with STD=sounding data. Compared are profiles ofRϱ and local estimates of heat and salt fluxes for various structural zones.
