Abstract
Major positive air temperature anomalies in the coastal areas of the Sea of Okhotsk and the Sea of Japan in 1950—2021 are considered according to the meteorological network. The intra annual variation in the number and frequency of occurrence of major positive air temperature anomalies in the periods 1950—1979 and 1980—2021 are calculated. It is shown that the frequency of occurrence of these anomalies in all months of the year in 1980—2021 is much higher than in 1950—1979. The maximum number of the anomalies was indicated through January to March of 1980—2021 in the northern part of the Sea of
 Okhotsk. The maximum frequency of occurrence of the anomalies was in March for all stations of the Sea of Okhotsk. What about the stations situated in the coastal areas of the Sea of Japan, the maximum frequency of occurrence of the anomalies was indicated in May. It is shown that the difference between the climatic
 peculiarities of 1950—1979 and 1980—2021 were determined by changes of the circulation regime in the centers of action of the Asia-Pacific region atmosphere. During winter periods of 1980—2021, the frequency of occurrence of major positive anomalies was determined by the tropospheric through regime near the
 eastern coast of Asia and by the position of the Okhotsk tropospheric cyclone while in warm periods of 1980—2021 it was determined by the circulation regime variability in the area of the Asia depression and of the Hawaiian anticyclone, their intensity being increased as compared to those of 1950—1979.
