本文用中美海气联合考察3个航次的常规观测资料,分析了西太平洋赤道附近洋面上的边界层特性,平均情况下,ΔT(=T_(10)-T_s)小于-2℃,Δe(=e_(10)-e_s)近于-10hPa,近海面层的温度层结基本上呈现为不稳定层结.用层结订正后的整体输送系数方法,计算了动量通量,感热和潜热通量.在西太平洋10°N—10°S海面上,波纹比β小于0.1,潜热通量远大于感热通量,感热和潜热通量主要是从海面向大气输送. In this paper, the common observation data of three voyages from the Sino-US joint study of the ocean voyage are used to analyze the boundary layer characteristics of the ocean near the equator of the western Pacific. In average, ΔT (= T_ (10) -T_s) is less than -2 ° C, Δe = e_ (10) -e_s) is close to -10hPa, the temperature layer of the near-sea surface layer basically shows unstable stratification.The momentum flux, sensible heat and latent heat Flux. The wave ratio β is less than 0.1 on the 10 ° N-10 ° S surface of the western Pacific. The latent heat flux is far greater than the sensible heat flux. The sensible and latent heat fluxes are mainly transported from the sea surface to the atmosphere.
