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(850hPa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.Abstract: In this paper,weintroduced a kind of ageost rophic ω equation suitable for the analy sisin 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 suit able for the operational analysis and forecast application,the test and experiment show that the applied result was satisfied.
