Long-term variations in the frequency of typhoons and their connection with various formation factors

Abstract

Variations in the frequency of tropical cyclones in the Northwest Pacific in 1961-2015 and their connection with various factors are analyzed. The examined factors are the occurrence rates of the certain patterns of atmospheric circulation (according to the Vangengeim-Girs classification) in the Pacific-American sector, sea surface temperature in the North Pacific, and the position of the North Pacific High center. Steady relationships between these parameters are revealed.
