| Abstract: | The B-model and the IAPAS (Institute of Atmospheric Phy-sics, Academic Sinica) limited fine-mesh model are nested in one way,and three schemes, i. e., the tendency correction scheme, the relaxationmethod and the radiative lateral boundary condition scheme, are tested.Tests show that the stability for the integration using the first schemeis the best. Several heavy rain occurrences during the Meiyu period of1986 are studied using the nested fine-mesh model, the forecasting resu-lts of which is greatly improved, with the accuracy of the rainfallvalues increased by more than 20% and the precipitation distributioncloser to actual conditions. The nesting technique stabilizes the integra-tion of the fine-mesh model, lessens the reliance on smoothing, andlengthens time validity of precipitation forecasting. The effect of the boundary conditions on the heavy rain system is also examined. |
