针对雷暴的双偏振雷达观测量与闪电频次的关系研究

Study on the Relationship Between Dual Polarization Radar Observations of Thunderstorms and Lightning Frequency

利用广州市双偏振天气雷达与闪点定位观测网数据,对雷暴的双偏振雷达观测量与闪电频次的关系进行研究和分析。结果表明,差分相移率、差分反射率与水平反射率能够反映雷暴发展变化的特征,零滞后相关系数能够判断雷达回波降水类型与非降水,和闪电频次并没有太大的相关性。

Based on the data of Guangzhou dual polarization weather radar and flash point positioning observation network,the relationship between dual polarization radar observations of thunderstorms and lightning frequency is studied and analyzed.The results show that differential phase shift,differential reflectivity and horizontal reflectivity can reflect the characteristics of thunderstorm development,and zero lag correlation coefficient can judge that there is no great correlation between radar echo precipitation type and non-precipitation and lightning frequency.
