| 摘 要： | 将辐射参数化子程序与中国科学院大气物理研究所降水有限区域模式结合 ,进行数值模拟 ,所得结果合理。辐射子程序能模拟并提供各高度及地面的辐射收支、温度、湿度日变化。对于大尺度降水过程 ,辐射使夜间降水量显著增加 ,是夜间降水多的原因之一。而辐射使白天降水有小量增加。

| Abstract: | The subroutine of radiative budget may supply the radiative temperature change of every layer and the daily variation of the ground temperature and evaporation.When the subroutine of radiative budget was conected with dynamical numerical rain forcast model,the rain was significantly increased at night but slightly increased at daytime. |
