TYPES OF ATMOSPHERIC PROCESSES AND RELATED WEATHER CONDITIONS OVER THE BERING SEA

S. Yu. Glebova

The analysis of mean 10-day maps of surface pressure for 1984-1998 demonstrated that Bering Sea weather conditions (mainly, the direction of wind transport) are determined by six types of synoptic processes, of which two types (I and II) are formed mainly in warm months, type III is formed in the fall, and types IV, V, and VI are formed in a cold season. The long-term variability of the total annual frequency of each type is shown to change rhythmically, with periods of 2-3, 4-5, and 8-9 years, which can be used for forecasting purposes.
