河南省闪电活动与复杂下垫面之间的相关性分析

Analysis about the Correlation between Lightning Activity and the Complex Underlying Surface in Henan Province

  • 摘要: 采用2007-2015年河南省ADTD闪电定位资料,分析河南省的闪电时空分布特征,研究闪电与海拔高度、城区、水体沼泽和丘陵旱地等不同下垫面的相关性.河南省闪电主要集中在4-8月发生,日变化呈现"双峰"型;闪电密度与平均海拔高度、城区面积呈正相关;水体沼泽区域雷电强度大,水体沼泽与丘陵旱地间的过渡区域闪电密度增加明显;油田和露天煤矿开采区的闪电密度和雷电强度都偏大.

     

    Abstract: Based on the files of the ADTD from 2007 to 2015 in Henan province, the features of the lightning characteristics of temporal and spatial distribution were analyzed, and the correlation between lightning and urban altitude, water, paddy field, dry land or other different underlying surfaces were studied. In Henan province, lightning mainly happened from April to August, and lightning daily variation displayed a typical bi-peak pattern. Meanwhile, there existed a positive correlation between the distribution of lightning density characteristics and the city construction range and the average altitude. Besides, lightning stroke intensity was strong in water and swamp areas, especially in transition area between hills dry field and water and swamp areas. Lightning density and intensity in oil field and open pit coal mine exploitation areas were slightly higher than surrounding areas.
