| 摘 要： | 针对短期预报中的非相变非绝热过程影响进行了数值试验。结果表明。非相变非绝热过程对短期天气预报的影响，主要体现在降水要素的预报上。在本个例中，对于雨区分布和降水量。若忽略非相变非绝热过程。将引起大陆上降水预报的较大偏差。预报降水量明显减少。

| Abstract: | Numerical experiments are made on the effect of non phase change diabatic heating process in short term forecast. The results show that its effect on quantitative precipitation forecast is significant. If omitting the process, the forecasts of rainfall amount and its distribution have obvious departure from observation . And, the rain belt in some region of the main land disappears or appears in error, the rainfall amount decreases evidently. |
