The variation of warm pool in the equatorial western Pacific and its impacts on climate

The variation of warm pool ocean temperature in the equatorial western Paci fic and its impacts on climatic change are studied in the present paper. Th e SSTs in the warm pool region not only have seasonal variation but also ha ve interannual variation more clearly; The influence of anomalies of SST in the warm pool region on the East Asian monsoon is studied with data analys is; And the impact of SSTA in the warm pool region oh the teleconnection (w ave-train) in the atmospheric circulation is still investigated. The influe nce of ocean temperature anomalies in the warm pool subsurface on the occur rence of ENSO is also discussed by using data analysis and modelling with C GCM. All above-mentioned studies show that the situation of ocean temperatu re: in the warm pool region in the equatorial western Pacific plays an impo rtant role in the global climatic variation.
