Study on the characteristics of the marine boundary layer in the Equatorial Pacific

In this paper the variations of the wind, temperature, humidity and turbulence in the atmospheric boundary layer over the tropical ocean are analysed by use of observational data with tethersonde over the Equatorial Pacific of 165°E from November 19,1989 to June 29,1990.According to the analyses, it is pointed out that generally the thereto-dynamic structure of the Marine boundary layer in the tropical ocean area remains in a state of connective boundary layer owing to higher temperature of the sea water.Generally, the cumulus generated by local convection exists in the mixed layer, and the cloud top is the top of the mixed layer.The turbulent kinetic energy in the surface layer (less 0.4 Z₁) and in the capping inversion layer is in exceedingly unbalanced state.
