摘　　要：利用NCEP再分析资料、常规观测资料、卫星资料、南宁机场雷达资料和自动观测站数据,对2014年9月16日至17日南宁机场出现的强降水过程进行分析和总结。结果表明:该强降水过程是由1415号台风"海鸥"中心北侧螺旋雨带及台风外围云系发展的中尺度对流云团直接造成的,低空急流是中尺度对流系统的建立者和维持者,物理量场显示水汽输送、动力条件、层结稳定性均为强降水云团的发展和维持提供了很好的条件,机场实况气象要素的突变对于暴雨天气的预报具有一定的参考价值。Based on NCEP reanalysis data, conventional observation data, satellite images, Nanning Airport radar maps and automatic observation station data, a heavy rainfall process occurring in Nanning Wuxu International Airport on 16 September 2014 were summarized and analyzed. The results show that： the spiral rain bands on north side of No. 1415 typhoon center and mesoscale convective clouds led by the typhoon periphery nephsystem were the main causes of this heavy rainfall, while low-level jet is the founder and sustainer of mesoscale convective systems. Physical field shows that water vapor transport, dynamic condition and the stability of stratification provided excellent conditions for developing and maintaining strong precipitation clouds. Abrupt changes of meteorological real-time elements have certain reference value for heavy rain forecast.
