摘      要：Based on the multi-year average NCEP/NCAR reanalysis data and NOAA s OLR data,the climatic characteristics of the tropical convection in tropical western Pacific and Indian Oceans as well as its relationship with western Pacific subtropical high (WPSH) is shown as follows:on short-term scales,the tropical convection that has significant influence on western Pacific high s latitudinal movement is located in the area of the South China Sea to the Philippines,which is the 2-day precursor prior to WPSH s latitudinal fluctuation,that is,WPSH is shifting to north 2 days after the tropical convection becomes more active,and vice ***,the tropical convection has less effect on WPSH s longitudinal movement.
