| 摘 要： | 本文首先用实测资料分析了0212号台风"北冕"造成福建大暴雨过程的环流形势和物理量场特征,指出低空偏南风急流的北抬和加强为远离风暴中心的福建东南沿海大暴雨提供了有利的水汽和动力条件.然后用中尺度模式(MM5)模拟分析了低空偏南风急流强度变化对本次暴雨过程的影响,结果表明低空急流强度变化对福建东南部的暴雨落区及强度有很大影响.

| Abstract: | Based on the real data, the circulation features and the physical conditions of heavy rain in Fujian caused by typhoon 0212 "Kammuri" are analyzed. The results reveal that northward moving low-level south-west jetwould causefavorable thermodynamic, moisture and dynamic conditions for the heavy rainfallin the south-east Fujian. Then, by means of MM5 model, the changes of precipitation and meteorological elements were studied after low-level jet was weakened The results demonstrate that the low-level jet has important effects on the heavy rainfall inthe south-east Fujian. |
