Impacts of Land-Surface Process Parameterization on Model Predictability of Two Kinds of Heavy Rainfall Events
陆面参数化方案对两例不同类型暴雨可预报性的影响

Through numerical model sensitivity experiments,the impacts of land-surface process parameterization on the model predictability of two heavy rainfall events are studied.The experiments of closing land-air fluxes in the model show that for advective precipitation,such as the severe flood near the Huaihe River basin during 3-4 July 2003,the land-air fluxes contribute little and the model forecast represents small dispersion or relatively high predictability.For evaporative rainfall,such as the shower during ...
