摘要
选用1989年7月14日20时南京站的实测探空为初始资料,应用许焕斌的二维可压缩大气云尺度模式,对副热带高压(以下简称副高)后部的强雷暴产生及发展进行了数值模拟和分析。模拟结果与实际雷暴的出现情况较一致,并通过不同初始扰动方案模拟结果的对比分析,表明扰动方案1对这次过程的模拟效果最好。
Real sounding data for 20 BST,14 July 1989 over the Nanjing area are selected as Initial condition and a two-dimensional compresslve atmospheric cloud scale modelfrom Xu Huanbln is used.The occurrence and development ofsevere thunderstorm behind a subtropical high are analysed and numerically simulated.The modelingresults are consistent with the occurrence and development of real thunderstorm, and through comparative analysing the simulative results of different initial disturbance, we find the best disturbance scheme.
