Abstract

Abstract

The found of well-defined zones of swell dominance,termed "swell pool",located in the eastern areas of the Pacific are presented in this paper,by calculating the global distribution of swell index in 2000.The global monthly mean wave transport for each month of 2000 is derived by taking advantage of the ECWM Freanalysis wave products.By comparing the monthly mean wave transport and monthly mean wind field from QUICKSCAT both of 2000,large difference is found between the wave transport direction and the wind direction in eastern area of the Pacific,approximately 90°,which may serve as an evidence for proving the existence of the swell pool in this Pacific.Analysis also show that the sources of swell in eastern tropical areas of the Pacific mainly locate in the corresponding regions of wester lies of South Pacific and North Pacific,respectively.Acalculation area is defined with boundaries lie on 2.5°N and 2.5°S(from 125°W to the western terrestrial boundary of America) to calculate the swell-caused net Stokes transport into the tropical region.Strong relationships are found between the net Stokes transport across the two latitudinal boundaries and wind intensities,for each specific month.It is pointed out that the bulk transport of swell could have a potential influence on the ocean circulation system.
