摘　　要：根据中国夏季暴雨系统的有关特点，导出一种适用于低层（８５０ ｈ Ｐａ 附近）单层ω诊断的非地转ω方程，它有别于迄今各种以“平衡方程”约束的非地转 ω方程。其中还适当地隐含非绝热作用，也包含了低层摩擦强迫。整个强迫场仍可写成一种简洁直观的矢量（ Ｑ）散度形式，以便应用于一般气象台业务分析预报中。In this paper,we introduced a kind of ageostrophic ω equation suitable for the ω analysis in a lower layer aimed at the summer heavy rain system in China,it is different from all kinds of ω equation limited by balance equation till today. It includes diabatic heating factor and friction effect in lower layer. All force field can be written by a simple vector ( Q ) divergence suitable for the operational analysis and forecast application,the test and experiment show that the applied result was satisfied.
