SOME SPATIAL AND TEMPORAL CHARACTERISTICS OF THE SURFACE TEMPERATURE FIELD IN THE NORTHWESTERN PACIFIC OCEAN

G. A. Vlasova

Numerical characteristics of anisotropy of the surface temperature field in the northwestern part of the Pacific Ocean are calculated and analyzed using the archives for 1960 and 1964—1985 and a statistical method. It is shown that one or two years after the El Nino events, the Kuroshio intensifies and the heat energy of the water area increases. Seasonal features of the space and time characteristics of the temperature field are determined. Winter seasons are distinguished by the highest uniformity and maximum sizes of the sea surface temperature anomalies (SSTAs). Summer seasons are characterized by the opposite pattern: the SSTA field is anisotropic and dimensions of the SSTA area are minimal. Spatial dimensions of temperature inhomogeneities decrease from 4000 km in winter to 1300 km in summer.
