| 摘 要： | 1 INTRODUCTION An important constituent in the Asian summer monsoon system, the West Pacific subtropical high (simplified as the 揌igh) is closely related with the activity of summer monsoon via the changes in intraseasonal intensity and progression[1 - 8]. Zhang et al[5]. discuss the relationship between seasonal jumps and anomalous location of the Highs ridge and onset of low-latitude westerlies and tropical convection in summer, with the finding that the northward jump of the High is …

| Abstract: | Based on the wavelet packet decomposition/reconstruction method and the NCEP/NCAR daily reanalysis data set, the relation between the south Asian summer monsoon and the west Pacific subtropical high seasonal variation was discussed, and a corresponding summer monsoon frequency-band energy criterion was defined and introduced for diagnosing the west Pacific subtropical high. Besides, some existing characteristics and rules about the west Pacific subtropical high were further argued and proofed, a few new phenomena and correlation between the south Asian summer monsoon and the west Pacific subtropical high were also revealed and presented. |
