NUMERICAL MODELING OF HEAT AND FRESHWATER FLUXES, TEMPERATURE, AND SALINITY AT THE JAPAN SEA SURFACE

Seasonal variability of vertical salinity distribution in the Japan Sea is considered. On the base of high accuracy data from the databases WODC-2013 (USA), JODC (Japan), and the databases of Far-Eastern State Hydrometeorological Institute and Pacific Oceanological Institute (Russia), several cases of salinity minimums are analyzed and interpreted taking into account seasonal variability of salinity profiles. High vertical homogeneity by salinity is noted for the Japan Sea waters, and the subsurface salinity minimum can be considered as a result of continuous changes of freshwater balance. It could be formed in the layers from the sea surface to 150-250 m as a temporary local extreme caused by prevalence of evaporation over precipitation on the sea surface in some seasons - that’s why it is observed seasonally. There is concluded that such conservative patterns as water masses are absent in the sea, at least in its active upper layers, but vertical salinity profiles are changing permanently under influence of changing freshwater fluxes, and their extremes appear or disappear in compliance with the dialectic laws.

Analysis of the long-period changes of the surface thermal characteristics in the Japan Sea, including the ice cover of Peter the Great Bay, was carried on the basis of the regional databases formed from open sources. The relationship of the observed changes with large-scale processes characterized by well-known climatic indices was investigated. It was revealed that surface temperature changes in the Japan Sea, its Northern part and in Peter the Great Bay in winter and summer occur synchronously. In the new century (2001–2017), the growth rate of the sea surface temperature slowed down in comparison with the last 25 years of the 20th century. The most influential in these areas were the large-scale processes, which are characterized by the index of the Siberian anticyclone and the West Pacific index. We also analyzed the sustainability of the statistical relationships between regional thermal characteristics and large-scale climate indices. Special attention was paid to the change in the character of the relationships at different time periods. The pronounced rearrangements of the linkages accompanied by a change in the sign of the correlation coefficients corresponded to the well known climatic regime shifts in most of the cases under study. The most notable restructuring occurred in 1988/89.
