There exists a tongue-shaped swell-dominance pool known as Swell Pool（SP） in the Eastern Pacific *** monthly-mean wave transports（WT） for each month of 2000 is computed using the wave products of ECMWF reanalysis *** comparing the 2000 monthly-mean WT and monthly-mean wind field from QUICKSCAT,large differences are found between the wave transport direction and the wind direction over the Eastern *** may serve as an evidence for the existence of the SP in this *** work done in this study indicates that the sources of swell in the Tropical Eastern Pacific（TEP） are in the westerly regions of the Southern and Northern Pacific.

Large-scale water transport is one of the key factors that affect sea surface temperature anomaly（SSTA） in the eastern equatorial Pacific（EEP）.The relationship between the wave transport in the tropical Pacific and the SSTA in the EEP is examined by different methods,including band-pass filtering,period analysis,correlation analysis,significant analysis,and empirical orthogonal function（EOF） *** have found that the eastward shift of the wave transport anomaly in the tropical Pacific,with a period of 2 a and enhancing the transport of warm waters from the western Pacific warm pool,precedes the increase of sea surface temperature（SST） in the *** wave transport and the SSTA in the EEP have a maximum correlation of 0.65 with a time-lag of 6 months（transport variation precedes the temperature）.The major periods（3.7 a and 2.45 a） of the wave transport variability,as revealed by the EOF analysis,appear to be consistent with the SSTA oscillation cycle in the *** on the first occurrence of a significant SSTA in the Ni？o 3 region（5°S–5°N,90°–150°W）,two types of warm events are *** wave transport anomalies in two types present predominantly the west anomaly in the tropical Pacific,it is that the wave transport continues transport warm water from west to east before the onset of the warm *** impact of wave-induced water transport on the SSTA in the EEP is confirmed by the heat flux of the wave *** wave transport exerts significant effect on the SSTA variability in the EEP and thus is not neglectable in the further studies.
