| Abstract: | In this paper, fluxes of momentum and sensible heat are discussed with the data collected by tethered balloon sounding system
over the Philippine Sea during the cruise of the R/VSCIENCE 1 from September through October in 1987. These fluxes were calculated using the semempirical flux-profile relationships of
Monin-Obkhov similarity theory with observed data. The friction velocityU. was determined by the observed data's least-square fit with the similarity formulae under stable, neutral and unstable conditions.
The roughnessZ
0 was determined byZ
0=a1 (U*/g), then substituted into the similarity formulae to computeU
* again. The final values ofU
* andZ
0 could be determined through this iteration. The flux temperatureθ
* was calculated from the temperature profile withZ
0 determined above. Finally the fluxes of momentum and sensible heat, and the drag coefficientC
D were obtained by computation withU
*
θ
* and the wind speed (U
10) at 10 meters above the sea surface.
