A Numerical Experiment of the Effect of Large Scale Heating of Condensation

In this paper, the large scale heating of condensation is added into the adiabatic scheme of the five level primitive equation model. The 48-hour forecast for the cyclone development over the Yellow River has been obtained. By contrast with the prognostic charts of the adiabatic scheme, it is quite evident that the large scale heating of condensation reinforces the intensity of the cyclone and improves the prediction.The conditions of the condensation are revised by considering the experience of synoptic meteorologists. We have tried a few cases and obtained eventually a satisfactory result.
