Relation between the Frequency of Typhoon Formations and Sea Surface Temperature

[摘要] The lagged correlations between the annual frequency of typhoon formations and monthly sea surface temperature in the North Pacific were examined. The lagged correlations were low even in the months near the period of typhoon formations. The largest correlation coefficients appeared in October of two years before. The regions of significant positive correlation are located in the eastern Equatorial Pacific. The northwestern part of the North Pacific showed negative correlation. In general, the values of the negatvie correlations were small in magnitude compared to the positive correlations.
