By comparing model simulation with an observed precipitation formed by stratuscloud system, the new scheme shows the improvement of prediction precipitation.
利用新方案模拟了一次层状云降水过程，新旧方案降水模拟结果的对比表明新方案的降水预报效果有所改进。

Simulation results show that targets can be found more easily in cumulus or stratus than in undulance cloud, because undulance cloud is more abrupt change in its intensity.
