| Abstract: | Based on the wind velocity and temperature gradient data of surface layers from three kinds of underlying surfaces, the sensible heat flux and the coefficient of heat exchange are obtained through iteration using the profile formula of wind velocity and temperature. Therefore the relationship formula between K h/K w and stabilityξis established. And then the latent heat flux is calculated using the aerodynamics method and Bowen ratio-energy balance method, respectively. The calculated results of these two methods are compared with each other. |
