摘　　要：利用多普勒雷达资料、NCEP/NCAR再分析资料及探空资料,分析淄博市雷电灾害的预警预报方法。结果表明,35、40 d BZ回波强度顶高分别突破-10、-15℃等温度高度层,对雷电预警效果较好。雷电活动均发生在垂直累积液态含水量为20~50 kg/m3的区间,可将其作为判断雷暴发生的充分条件,回波顶高>10 km是预警雷电发生的一个较好的指标。本文归纳出雷电预警流程,并选取4次强对流天气过程进行效果检验,发现该流程在雷暴天气中具有较好的预警效果。Using Doppler radar data,NCEP/NCAR reanalysis data and sounding data,the lightning disaster warning and forecasting method was analyzed in this paper. The results showed that,the echo top of 35,40 d BZ breakthrough temperature layer of-10,-15 ℃ had better lightning warning effect. Lightning activity occurred in the VIL of 20-50 kg/m3,which could be as sufficient conditions for the judgment of thunderstorms. The echo tops height greater than 10 km was a good indicator to lightning. This paper also concluded the lightning warning process and selected four strong convective weather process to test the effect,and found that the process had good warning effect in thunderstorm weather.
