The western tropical South Pacific, where there is an evident decadal variability, is the key region of the ENSO decadal variability.

In this paper, the deep casting CTD data collected around the 1986/1987 ENSO event in the western tropical Pacific Ocean(141 165 E,140 100 W)are used to calculate the spatial and temporal variabilities in potential energy relative to different isobaric surfaces in the sea area.

Based on the observed data during 1986-1990,the longitudinal variabilities and vertical distributions of buoyancy frequency in the western tropical Pacific Ocean are analyzed to expound the relation of buoyancy frequency to seawater stability and potential energy of oceanic internal wave.

Interannual variability of sea level in the western tropical Pacific Ocean are discussed in this paper,on the basis of the monthly mean sea level during the period of 1975 -1988 provided by TOGA SEA LEVEL CENTER.

Decadal variations of the subsurface and intermediate waters in the western tropical Pacific derived from Argo and historic data;

Simulation of undercurrents in Western Tropical Pacific:(I)Model configuration and validity of results

The analyses of the sounding data of the atmosphere obtained from Sino-American joint air-sea interaction studies in the western tropical Pacific revealed that inversion layers occur within the lower atmospheric layer over the western tropical Pacific warm pool area where vertical convection of air prevails.

Using monthly mean National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis data for the period 1958-1996, based on a new circulation index in the tropical western Pacific region, this paper investigates extreme winter circulation conditions in the northwestern Pacific and their evolution.

In order to study the effects of SST anomaly in tropical western Pacific during winter and spring on the early summer monsoon in East Asia, a set of numerical experiments is conducted using OSU AGCM.

1, an analysis is made on the atmosphere-ocean heat exchange over the Tropical Western Pacific.

Variation of SST and its time—space distribution in the tropical western Pacific and the Indian Ocean are studied by using the comprehensive ocean—atmosphere data set (COADS).
