The energy components of sixteen Soil-Vegetation Atmospheric Transfer (SVAT) schemes were analyzed and intercompared using 10 years of surface meteorological and radiative forcing data from the Red-Arkansas River basin in the Southern Great Plains of the United States. Comparisons of simulated surface energy fluxes among models showed that the net radiation and surface temperature generally had the best agreement among the schemes. On an average (annual and monthly) basis, the estimated latent heat fluxes agreed (to within approximate estimation errors) with the latent heat fluxes derived from a radiosonde-based atmospheric budget method for slightly more than half of the schemes. The sensible heat fluxes had larger differences among the schemes than did the latent heat fluxes, and the model-simulated ground heat fluxes had large variations among the schemes. The spatial patterns of the model-computed net radiation and surface temperature were generally similar among the schemes, and appear reasonable and consistent with observations of related variables, such as surface air temperature. The spatial mean patterns of latent and sensible heat fluxes were less similar than for net radiation, and the spatial patterns of the ground heat flux vary greatly among the 16 schemes. Generally, there is less similarity among the models in the temporal (interannual) variability of surface fluxes and temperature than there is in the mean fields, even for schemes with similar mean fields.  相似文献

滇西耿马盆地构造—沉积综合分析     

赵易奎  赵泽江 《矿物岩石》1998,18(1):54-59

滇西耿马盆地位于三江褶皱系保山褶皱带的耿马—澜沧复背斜,面积１９５ｋｍ２,接受广泛的河湖相沉积,为典型的第三系小型陆相盆地。盆地内沉积受构造控制明显,沿边界断层主要发育冲积扇、近岸水下扇沉积,远离断层发育深湖相或半深湖相沉积。耿马盆地的构造样式与沉积展布在滇西具有极好的代表性,故从构造－沉积相互作用角度对其分析,对于指导滇西其他第三系盆地的勘探有重要意义。  相似文献
