摘要	In this study, three high frequent occurrence regions of tropical cyclones (TCs), i.e., the northern South China Sea (the region S), the south Philippine Sea (the region P) and the region east of Taiwan Island (the region E), are defined with frequency of TC's occurrence at each grid for a 45-year period (1965-2009), where the frequency of occurrence (FO) of TCs is triple the mean value of the whole western North Pacific. Over the region S, there are decreasing trends in the FO of TCs, the number of TCs' tracks going though this region and the number of TCs' genesis in this region. Over the region P, the FO and tracks demonstrate decadal variation with periods of 10-12 year, while over the region E, a significant 4-5 years' oscillation appears in both FO and tracks. It is demonstrated that the differences of TCs' variation in these three different regions are mainly caused by the variation of the Western Pacific Subtropical High (WPSH) at different time scales. The westward shift of WPSH is responsible for the northwesterly anomaly over the region S which inhibits westward TC movement into the region S. On the decadal timescale, the WPSH stretches northwestward because of the anomalous anticyclone over the northwestern part of the region P, and steers more TCs reaching the region P in the greater FO years of the region P. The retreating of the WPSH on the interannual time scale is the main reason for the FO's oscillation over the region E.
