| 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 subtropic high were further argued and proofed, a few new phenomena and correlation between the south Asian summer monsoon and the west Pacific stubtropical high were also revealed and presented. |
