Abstract : The Influence of the Initial Soil Wetness and Vegetation Cover on the Short-Term Climate Abstract The influence of the initial soil moisture and vegetation cover on the short-term climate was quantitatively assessed through the use of the limited area model. The sensitivity of the used Egypt-Eta (Egeta) model to changes in initial soil moisture (ISM) and vegetation cover is determined by repeating three months integration with the same initial and boundary conditions as the Normal Run (NR). It is found that, the changes in the three months mean forecasts of surface air temperature and surface evaporation depends on the ISM and vegetation cover. The impact on the upper atmosphere is small and is largely confined to lower levels. The sum of latent heat, sensible heat and soil heat fluxes are strongly governed by the net radiation at the earth’s surface. The partitioning of energy between latent, sensible and soil heat fluxes is determined by the dryness of the ground and by the surface temperature. The associated rainfall was strongly influenced by the increase of the ISM and vegetation cover, where the increase of precipitation substantially is over the regions where the soil moisture is initially increased.
