桂东南“6.28”大暴雨触发机制分析
Trigger Mechanism of “6.28” Heavy Rain in Southeastern Guangxi
摘要
Abstract
Basing the heavy rain on June 27-29 in Yulin City,the dynamic mechanism was analyzed.The results show that： The heavy rain occurs in the strong meridional circulation of two slots and two ridges.The plateau trough moving eastward provides storms a favorable dynamic condition.On 850hpa,the shear line fast moving southward triggers local instability energy releasing.The coupling of low-level strong convergence and high-level strong divergence is conducive to the development of vertical velocity and MCS.The heavy precipitation occurs in the most productive periods of MCS development.关键词
