| Abstract: | Based on the 4-layer db1 wavelet packet and shannon entropy decomposition/reconstruction method and the NCEP/NCAR daily reanalysis data set,the correlation between the South China Sea summer monsoon and the Northern Hemisphere Pacific subtropical high seasonal modality/shift was studied and discussed,and a corresponding summer monsoon frequency-band energy criterion was defined and introduced for diagnosing the Pacific subtropical high's modality/shift. A few new phenomena and correlation between the South China Sea summer monsoon and the Northern Hemisphere Pacific subtropical high were also revealed and presented. |
