摘要
利用山东地区2006年6月至2007年10月的闪电资料和的湿度资料,分析了该地区闪电和湿度的季节变化特征以及二者的相关关系.结果表明:正、负闪电频次有一致的双峰谷季节变化特征,主峰值在夏季8月份,分别占全年闪电频次的35.58%和59.93%,次峰值在春末5月份,谷值在冬季,但负闪电在春末5月份的次峰值并不明显;湿度季节变化特征呈单峰值特征,峰值除鲁西北在夏季7月份,其他三地区均在夏季8月份,谷值都在春季4月份,但在秋冬季的下降变化中出现了波动现象;闪电频次、闪电平均强度与湿度的季节变化有较好的一致性,存在正响应,但都出现了春季异常.
Based on the data of lightning and the relative humidity of the surface from June 2006 to October 2007 in Shandong, both the characteristics of seasonal variation of the lightning activities and the humidity, and the regional response of lightning activities to the relative humidity was analyzed. Result showed that： positive and negative lightning frequency have a consistent seasonal variation, there are a double peak form, the main peak is in August, and the second peak is in May, valley is in the winter. However, the second peak of negative lightning is not obvious. The characteristics of seasonal variation of the relative humidity have a single peak characteristic, the peak of Luxibei is in July, but the other three regions is in August, and the valley is in April. The seasonal changes of lightning frequency, the average intensity of lightning and the relative humidity are roughly the same, there are to respond, but they all appeared in the spring of abnormal; humidity with only a rough description of the seasonal variation of lightning activity.
