The Effects of Non-phase Change Diabatic Heating Process in Short Term Forecast

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.
