| 摘 要： | 推导出了一个新的锋区横切环流(Y-P平面上)流函数诊断方程，分析了诊断方程中强迫函数的物理意义及作用，并用淮河流域能量与水分循环试验(HUBEX)所取得的加密观测资料进行了验证。基于这个诊断方程设计出能描述锋区垂直环流特征的二维空间剖面综合分析图，总结出与锋区强暴雨发生有关的三类垂直环流概念模型，对江淮地区汛期暴雨预报有较好的指导作用。

| Abstract: | A new stream function diagnostic equation, which is suitable for describing the transverse circulation in frontal zone (Y-P cross-section) is derived, the physical meaning and effect of its various force functions in the diagnostic equation are analyzed, and it is validated by the intensive observational data in HUBEX. Based on the diagnostic equation, we designed a integrated analysis chart on a 2-D cross-section that can describe the character of vertical circulation in frontal zone, and concluding three kinds of concept models on vertical circulation, which can give better directions to the forecast of the storm rainfall in flood season of Changjiang and Huai River regions. |
