Temperature of the ocean surface as an indicator of thermodynamic processes in the northwest Pacific

The numerical computations and analysis of the anomalies of temperature of the ocean surface in the northwest part of the Pacific Ocean were carried out on the basis of the archival data for 1960 and 1964–1985. A five-year period of general instability of the annual average temperature was revealed (1973–1977). In this period, the year 1974 was the coldest and the year 1977 was characterized as extremely warm. We performed the analysis of the interannual and annual variability of the anomalies of temperature of the ocean surface and revealed common features and distinctions of the seasonal evolution of these anomalies for years with substantially different temperature conditions. A quasistationary zone of maximally heated waters was discovered in the band located (independently of the year and season) between 36 and 46°N to the east of 140°E. This zone coincides in space with the zone of the subarctic front and the south part of the subarctic region. The influence of the meanders of the Kuroshio Current was demonstrated. It is shown that their activity increases after the events of El-Niño and, hence, the thermal energy of the water area considerably increases and remains elevated for a period of 1–2 yr after the indicated events.
