| Abstract: | This paper analyzes the characteristics of super typhoons(STYs)over the western North Pacific(WNP)from 1965 to 2005 and describes the seasonal variability of STY activity.The relation between STY activity and the E1 Nino-Southern Oscillation (ENSO)as well as the possible reason for the influence of the ENSO on STY activity are also investigated.The results showed that about one fifth of the tropical cyclones(TCs)over the WNP could reach the rank of STY.Most STYs appeared from July to November while there was a highest ratio between number of STYs and total number of TCs in November.Most STYs appeared east of the Philippine Sea.In EI Nifio years,affected by sea surface temperature(SST),monsoon trough and weak vertical wind shear,TC formation locations shifted eastward and there were more STYs than in La Nina years when the affecting factors changed. |
