Characteristics of Weather and Climate over the Okhotsk Sea

다국어 초록 (Multilingual Abstract)

The Okhotsk Sea is unique natural object with climatic peculiarities. The climate of the Okhotsk Sea results from the general distribution of solar radiation during a year, and the characteristics of the atmospheric circulation that varies through a year. In cold half year the main pressure formations are siberian high and Aleutian low. Asian low centered on Afghanistan dominates over the Asian continent in summer. The North-Pacific sea surface is under effect of permanent North Pacific high. The changes in their position from year to year are very significant.
The anticyclonic activity over the Far eastern seas is one of the main factors for the formation of weather anomalies over the adjacent territories. The analysis of summer weather characteristics over the coast of Okhotsk and East Sea using the dafa obtained from Hydrometeorological stations during 1949~1990 showed that, to a great extent, distribution of the air temperature depends on thermal state of the Okhotsk Sea and atmospheric cirulation over it. We show some relations between weather characteristics and the intensity of atmospheric action center for the North Pacific high in summer when its ridge propagates to Okhotsk Sea.
Correlation coefficients between air pressure over the Okhotsk Sea and air temperature for the coastal areas reach up to 0.7. Analysis of the spatial-temporal distribution of main meteorolgical values over the Okhotsk Sea such as air pressure, and air temperature are also performed.
