Using a modified numerical model with higher resolution in both horizontal and vertical direction, the surface fluxes of the sensible and latent heat in the HEIFE region were diagnosed. Based on statistical analysis for the diagnostic fiuxes, the representativeness and setting for the location observational stations in the HEIFE region were investigated, a concrete scheme for setting up the observational stations in the HEIFE region with different underlying surface are obtained and the general principle of choosing the locations of observational staations with better erpresentativeness is proposed.
