| 摘 要： | 利用2013年4月30日8:00到5月1日8:00的MICAPS资料、NCEP1°×1°再分析资料、福建省区域自动站资料等,分析闽东一场在高空槽、低层切变和地面冷空气共同作用下的冷锋锋前暴雨天气过程。通过物理量结构分析发现,槽前西南急流为此次降水提供了充足的水汽,冷锋过境使得大气条件性不稳定,强的辐散场和锋面南压为此次暴雨提供了强的抬升条件。并浅析此次暴雨对铁观音茶青生产及品质的影响。

| Abstract: | A rainstorm process ahead of cold front in eastern Fujian, simultaneously influenced by upper trough, low level shear, and surface cold air, was analyzed based on the MICAPS data from April, 30th to May, 1st, 2013, reanalyzed data of NCEP 1°×1°, and data of Fujian Regional Automatic Station.With analysis on physical quantity structure, it found that the jet ahead of trough in southwest supplied sufficient water vapor for the rainstorm, the passed cold front made the air conditions unstable, and the strong divergence field and front pressed towards south formed uplift condition.Effects of the strong rainfall on production and quality of Tie Guanyin tea leaves were also analyzed. |
