PRELIMINARY ANALYSIS OF TURBULENT TRANSFER CHARACTERISTICS IN THE SURFACE LAYER OVER GUANGZHOU REGION

On the basis of the Monin-Obukhov similarity theory, a semi-empirical expression of universal functions is fitted by means of the iteration method. using the gradient observation data of wind and temperature in the surface layer. The characteristics of bulk transfer coefficient are studied and some empirical relationships among the bulk transfer coefficient, the wind speed and temperature are obtained. The applicability of the results is investigated using observation data.
