The Observation and Analysis of Sensible and Latent Heat Fluxes of Typical Surface in Huaihe River Basin
淮河流域典型地面水热通量的观测分析

During the 1998 HUBEX IOP (June and July), 3 kinds of micrometerological methods were used to estimate the sensible and latent heat fluxes. The authors analysed and compared the results obtained by the 3 methods. The results show that: (1) The latent heat flux estimated by Flux-Gradient method was agreement with that calculated by Bowen-ratio method, and was different from that calculated by the eddy correlation method; (2) Sensible heat flux and Bowen-ratio were bigger before Meiyu (heavy rainfall) and were smaller after Meiyu. The most of net radiation was used to evaporate from the surface.
