中文摘要：
利用WRF模式V3.6.1中3种基于经验公式的闪电参数化方案对2013-07-05江苏省内的1次飑线过程进行数值模拟,对比3种方案在模拟闪电位置和频数的特点,分析模拟结果的成因。结果表明：PR92w方案能够很好地模拟闪电的分布位置;PR92z方案的模拟结果和PR92w方案正好相反,闪电频数与实测结果有很好的一致性但分布位置出现偏移;LPI方案虽然能指示闪电分布区域,但对高闪电密度区的预报有一定误差。3种方案的模拟结果表明：垂直风速和雷达回波是影响模式预报闪电频数和分布的重要因素。因此,增大网格模拟精度和同化雷达资料是改善PR92方案模拟效果的重要途径。
英文摘要：
A squall line that occurred in Jiangsu Province on July 5, 2013, was successfully simulated with the WRF model by using three kinds of lightning parameterization schemes, which were based on empirical formulae. Comparative analysis of different schemes in simulating the distribution and frequency of lightning has been done. Furthermore, we have discussed the reasons of simulation errors, which lay good foundation for lightning monitoring and prediction. The results show that PR92 w scheme exhibiting the location of lightning is in good agreement with the observations, but the flash count has certain difference with the actual situation. Coincidentally, the results of PR92 z scheme is opposite with that of PR92 w scheme. Although forecast in high flash density using LPI is not so correct, it can indicate the distribution of lightning to some extent. Error analysis has revealed that vertical velocity and radar echo are the main factors of influencing the forecast in flash. According to the above results, increasing the grid precision and assimilating radar data is the main approach for improving the simulation results of PR92 schemes.
