Climatology of deep cyclones over Asia and the Northwest Pacific
A frequency analysis of deep cyclones with central pressure less than or equal to 990 hPa over Asia and the Northwest Pacific in the period 1958-1989 is presented. The most active areas of deep cyclones are: 1) Western Siberia, east of the Ural Mountains; 2) Northeastern China, east of the Mongolia...
