2、高空月温度变化相关性随高度减小而增加，与地面月相对湿度变化几乎无相关性，与高空月相对湿度变化呈正相关,但是相关系数不大。有无闪电条件的地面和高空温度都未发现有显著性差异，而地面和高空相对湿度都存在高度显著性差异。闪电强度与地面月温度变化虽然呈正相关，但是相关系数较小；与高空温度相关性较差。闪电强度与地面及高空湿度都呈现负相关关系。闪电强度大于或小于60kA时地面与高空的平均温度无显著性差异，而地面及高空的相对湿度均存在显著性差异。闪电与降雨方面：有闪电伴随购买全文在线加QQ139938848即付即发同时提供论文写作指导和学术期刊发表服务在:本立为学术立献总库合作提供I如有异溟请与总库或学校联系

3、"0的月降雨量与闪电活动的变化比较一致；月总降雨量和闪电的变化趋势相似,但是峰值时间不同。有闪电伴随降雨时，出现大降雨的概率明显大于没闪电伴随时候的概率。随着时段划分变长，地闪活动与对应降雨量的相关性更加明显。季节性闪电频次与降雨量回归方程R=0.0086F+137.04,R为降雨量,F为闪电频数,相关系数R=0.89。经显著性差异分析，在有无闪电条件下的降雨量存在高度显著差异。【英文摘要】Withthehelpofthelightninglocalizationdatefrom2007-2009ofWuhandistrict,thispaperanalysesthelightnin
