摘要: becomes more discernable after 1 month. The model results suggest that the landatmosphere feedback is an important mechanism for summer precipitation over Central United States. Vegetation growth and groundwater dynamics play a significant role in enhancing persistence of intraseasonal regional climate models. Their combined effects act to favor stronger land-atmosphere during season. simulated diurnal cycle improved by WRF with augmented Noah LSM. Moreover, we found coupling between soil moisture lifting condensation level (LCL) enhanced adding two components model. impact when relatively dry. This study suggests incorporating vegetation into would be especially beneficial seasonal forecast transition zones.
