摘要
利用常规气象观测资料和NCEP的1°×1°的分析资料,对2010年5月6日发生在广东省英德市强降水过程的影响系统、环流特征及相关物理量进行了诊断分析。分析发现此次持续性强降水过程主要是受高空槽、切变线等共同作用的结果.强劲的西南风场,向英德地区提供了充足的水汽;近地面层处于低槽边缘,位势不稳定能量增多,为强降水的产生提供了足够的触发机制。
According to normal meteorological observation data and 10×10 analysis data of NCPE, the influence system, circulation features and related quantities of the strong precipitation process occurring in Yingde City on May 6, 2010 are analyzed. It is founded that this constant process mainly resulted from the interaction between upper trough and shear line. The strong south western wind field provided abundant water vapor for Yingde area. Meanwhile, the fact that the surface layer was located on the edge of low trough and geo-potential unstable energy increased offered trigger mechanism for this process.
