Effects of wind waves of the Pacific westerly on the eastern Pacific wave transport

There exists a tongue-shaped swell-dominance pool known as Swell Pool（SP） in the Eastern Pacific region.The monthly-mean wave transports（WT） for each month of 2000 is computed using the wave products of ECMWF reanalysis data.By 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 Pacific.This may serve as an evidence for the existence of the SP in this region.The 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.
