摘要：

以深圳市为例，对近10 a闪电定位、人工观测雷暴日、天气雷达及探空资料进行分析，探讨闪电定位数据替代雷暴日人工观测的合理性和可行性。结果表明：（1）闪电定位数据与雷达回波具有较好的一致性，可用于替代雷暴日的人工观测。（2）基于最小二乘法，得到闪电定位数据与人工观测雷暴日最优匹配的半径范围为9.24 km，在该半径范围内，闪电定位得到的雷电日与人工观测雷暴日的年平均误差2.8 d，平均误差率4.3%。通过雷暴日和闪电定位数据之间的比例关系分析，发现两种观测数据的一致性较好。（3）雷暴日和雷电日的环流形势和天气系统基本相同，两种天气条件下温、湿廓线的相关系数均为0.99，且具有基本一致的环境物理条件。人工观测雷暴日和基于闪电定位得到的雷电日随闪电定位取值半径的变化特征及其二者关系的分析表明，闪电定位数据替代人工观测雷暴日的方法和结果具有较好的合理性。

Abstract:

Taking Shenzhen city as an example, the paper discussed the rationality and feasibility about replacing the conventional artificial observation of thunderstorm days with lightning position system (LPS) data by analyzing the lightning position data from ADTD and TLLS systems and thunderstorm days at Shenzhen weather station during 2007-2016, radar echo and sounding data, etc. The results are as follows: (1) LPS data was well accordant to radar echo, which indicated that the replacement of artificial observation of thunderstorm days with LPS data was feasible and reliable. (2) The optimal value of matching radius between LPS data and artificial observation thunderstorm days was 9.24 km by using the least squares method, and the annual mean error between thunderstorm days from conventional observation and calculated thunder-lightning days from LPS in that radius range was 2.8 days, the average error rate was 4.3%. The proportion relation showed the consistency between two observation approaches was good. (3) The weather systems, circulation situations and atmospheric stratifications on thunderstorm days and thunder-lightning days were basically similar, and the correlation coefficients of temperature and humidity profiles under two weather conditions were 0.99. Besides, the relation of thunderstorm days and thunder-lightning days with the change of LPS matching radius showed that the replacement of artificial observation of thunderstorm days with LPS data was very reasonable.

Key words: thunderstorm days, lightning position system, artificial observation, least square method
