Analysis of winter warm sea air intrusion to the western coast of the Strait of Tartary / Vasilevskaya L.N., Potalova E.Yu. // Hydrometeorological Research and Forecasting, 2020, no. 1 (375), pp. 6-20.

The local intrusions of warm sea air to the western coast of the Tartary Strait (the Sea of Japan) are studied using the daily difference in surface air temperature between Sovetskaya Gavan (northern station) and Vladivostok (southern station) during the winter months of 1966–2018. It is shown that the intrusions are most pronounced from the third ten-day period of December to the second ten-day period of January; the number of intensive sea air intrusions during 53 years increases in December and January and decreases in February. At the same time, the duration of the most intensive intrusions is at least 3 days, with temperature differences between the stations ≥4 °C. The atmospheric processes causing the intrusions are typified according to the similarity of synoptic conditions and the thermobaric field. The detailed assessment of development of these processes disturbing the complete pattern of the Far Eastern monsoon winter phase and the latitudinal distribution of air temperature is provided. It is shown that, in addition to the significant air temperature rise, the warm sea air intrusions cause the abnormal distribution of winter precipitation on the northwestern coast of the Sea of Japan.
