Abstract: In this paper, results of the fluxes of momentum, sensible heat and latent heat for the West Pacific Tropical Ocean Area (from 127°E to 150°E, 5°N to 30°S) are described. The data were collected by the small tethered balloon sounding system over this ocean area including 6 continuos stations from 11th of Octorber 1986 to the 15th of December 1986. These fluxes were calculated by the semiempirical flux-profile relationships of Monin-Obukhov similarity theory using these observed data. The results show that for this tropical ocean area the drag coefficient CD is equal to (1.53±0.25) ×10-3, and the daily mean latent flux HL is greater than its daily mean sensible flux H,, by factor of about 9.
