STUDY OF AIR SEA FLUXES AND BULK TRANSFER COEFFICIENTS ON “WARM POOL” OF THE WESTERN PACIFIC

A stratification modified model of the profiles is developed for a viscous sublayer of light wind,high temperature and humidity,over a smooth sea surface.The data of the gradient of wind,temperature and humidity near the sea surface of "warm pool" in the Western Pacific,obt ained by XiangYang Hong #5 R/V during TOGA COARE IOP,are calcul atedusing this model.Computing results show that there are about 50%-80% observations in unstable state,among them 10.3% are strong unstable.The effect of stratificat in on the air-sea fluxes and bulk transfer coefficients are much stronger than that of wind.These fluxes and coefficients increase with the increasing unstability by a fact or of 5 under the same wind.They vary from 0.3×10-3 to 3.2×10-3.It can be seen that the variations ae larger than those at other sea area justo wing to the effect of stratification.
