闪电产生氮氧化物(LNOX)区域特征计算(Ⅱ): LNOX计算结果分析

利用东北、北京和广东三地的闪电定位资料，计算分析了6种不同类型雷暴中闪电产生的氮氧化物总体、季节、空间分布和雷暴的不同发展阶段等特征。结果表明：虽然中高纬地区雷暴频数较低，年总产氮(N)量低于低纬地区，但单个雷暴平均产N量并不比低纬低。三地雷暴产N量的月份分布不相同，东北和北京地区的峰值月份出现在季节交换期的6月和9月，广东地区出现在对流相对旺盛的7月。低纬区的系统雷暴产N量主要发生在成熟阶段，而发展和消散阶段产N量很低，中高纬尽管成熟阶段产N量最高，但发展和消散阶段也有一定的比例。中高纬的局地雷暴产N量主要发生在发展和消散阶段，成熟阶段很低，而广东地区，三个阶段相差不大。进一步讨论了几种雷暴闪电参数与雷暴产生N量的相关性，得到系统雷暴正负闪电总数和雷暴产生N量的回归预报方程并讨论了误差。最后与文献1]的方法和Price的方法进行了比较。

Regional Characteristic Calculation of Lightning Productionof Nitrogen Oxides(LNOX)(Ⅱ): Analysis on Calculation Result of LNOX

Using the lightning location data of Dongbei, Beijing, Guangdong, the distribution characteristics of N produced by six different kinds of thunderstorms are calculated. \ \ The general, seasonal, space distribution and different stages of thunderstorm characteristics are analysed, the results show that because of the lower thunderstorm frequencies of middle and high latitude, the total N quantity produced each year is much lower than low latitude, but the N quantity produced by one thunderstorm is not lower. The seasonal distributions of the thunderstorm produced N in three different regions are very different: The peak months produced N of Beijing and Dongbei are in June and September which are the seasonal exchange periods, the peak months of produced N in Guangdong is in July when the convention is very violent. The main stage of system thunderstorm produced N of low latitude is the mature stage, it is very low in development and dissipiate stages, but in middle and high latitude there is some produced in devlopment and dissipate stages. The main stage of local thunderstorm produced N of middle and high latitude is the development and dissipiate stages, it is very low in the mature stage, but in the low latitude these stages produced are almost the same. The correlations of thunderstorm produced N and several lightning parameters are discussed. We get the regression forecasting equation of positive or negative lightning number and thunderstorm produced N and discuss the error. At last we compare the method used in reference \ and the method used by Price, the result shows that although his method is much more simple, the error of estimation to different regions and different kinds of thunderstorms is much larger.
