| 摘 要： | 本文分别讨论了求解ω场的三种模式:多层非线性ω诊断模式（模式A），非绝热ω诊断模式（模式B），中-α尺度ω诊断模式（模式C），并应用于一次梅雨锋暴雨过程的诊断，比较了它们的差异。结果表明，在进行中尺度ω诊断中最好使用模式C，也可使用模式A，且由两者分别得到的ω场差异不大。一般不用模式B，由于模式B计算量小，如果精度要求不高也可使用模式B。

| Abstract: | In this paper, three models which are used to solve theω–field are discussed respectively. The model A is a multi-layer nonlinearω–diagnostic models, model B is a diabatic one and model C is a meso– scale one. They are applied to diagnose a mei-yu front heavy rain process. The differences from each other are analysed. The results show that the model C or model A is better for diagnosing the mesoscaleω field and the difference between twoω fields obtained from the two models is small. Model B is not generally used, but it can be used if the precision requirements are not high in order to save the calculation amount |
