摘要: Energy budget is closely related to the hydrological cycle through evapotranspiration (ET) or latent heat. Hence, quantifying energy on different land uses critical for understanding water and providing useful use information decision makers. However, traditional methods, including in situ measurements model-only approaches, have deficiencies data availability, we still not yet fully realized how well budgets presented reanalysis sets. Therefore, this study, North American regional (NARR) set from 1992 2002 were employed investigate various (lake, wetland, agriculture, forest, urban) at a scale Florida. The results showed that lake urban areas had high values of budget, evaporation, low Bowen ratio, while wetland opposite treads because lowest evaporation rate. During drought periods, surface temperature, sensible heat becoming higher than those normal years conditions. Finally, by comparing with observed data, found NARR better assimilation precipitation observations demonstrated effects coefficient correlation relationships.
