摘要
Abstract
[Objective] The aim was to analyze the causes of "6.06" heavy rainstorm in Wangmo County in Qianxinan . [ Method] By dint of NCEP/NCAR 1° x 1° reanalysis data, FY-2E TBB data, ground seven elements and two elements automatic station data,the main influential system, and all kinds of physical quantity field features were analyzed while developing heavy rainstorm in upper reaches of Wangmo County in Qianxinan from the evening on June 5 to 08:00 on 6 in 2011. [ Result] The rainstorm was the result of cold air, which was provided by 850 hPa cold shear line and ground radiation line, and warm and wet airstream on the northwest edge of subtropical high. MCS was the main reason for such heavy rainstorm. Southwest warm and wet airstream in middle lower part provided sufficient water vapor for the rainstorm. The 850 hPa water vapor flux divergence center moved from north to south along ground convergence line to Qianxinan. Rainfall location and water vapor flux as well as convergence center were corresponding. The rainfall intensity also was consistent with the amount of water vapor flux and water vapor convergence. [Conclusion] The study provided reference for the report of heavy rainstorm.关键词
