摘　　要：本文利用“中美热带西太平洋海气相互作用研究”第１—８航次海面气象观测资料，计算分析了热带太平洋感热潜热通量的时空特征。分析结果表明在赤道海域，潜热通量远远大于感热通量。潜热和感热通量是从海面向大气输送的，且具有明显的年际变化和季节变化，日变化变幅甚小。radiate flix, latent flux,tropical Pacic Sea region Abstract Based on the observations during a ocean surface meteorological survey,conducted bythe project of“the Sino American Research Programme of the Air-sea Interaction in WestTropical Pacific”,analyses of the temporal and spatial characters of radiate heat and latentheat fluxes are made. The results show that the latent heat flux is much greater than the ra-diate heat flux.βis equal to 0. 05 in the equatorial sea area west of 165°E is 0.13 in the areanorth of 20°N,βis 0.01 in the equatorial sea area east of the international date line.Latentheat and radiate heat are transformed from sea surface to atmosphere,and have obvious an-nual andseasonal variations.
