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及潜热通量的时空特征。分析结果表明,潜热通量远远大于感热通量,在165°E以西赤道海域,β=O. 05;20°N以北,β=0. 13;更日线以东赤道海域,β=0. 01;且具有明显的年际变化和季节变化,也有日变化,但日变化变幅甚小。The meteorological observations obtained from eigth cruises of USA-PRC cooperative research program were used in estimating the latent and sensible heat flux in the tropical Pacific and analysing the spatial and temporal variations. The results indicated that the latent heat flux was far more greater than the sensible heat flux. β was 0. 05 at the equator west of 165°E, 0. 13 north of 20°N and 0. 01 east of the date line. The latent and sensible heat flux was transmitted mainly from sea surface to atmosphere, and the latent heat flux had significant seasonal, in-terannual and daily variations but the range of daily variation was small.
