摘要
文章选用呼伦贝尔市2014-2022年雷暴日数统计资料、闪电频次与强度观测资料等,主要采用气候倾向率等数理统计法,针对呼伦贝尔市近10年来闪电活动规律进行分析。结果表明,该地区雷暴发生频率较高,2014-2022年平均雷暴日数为131.1d,且以38.5d/10a的速率呈明显增加趋势。总地闪强度均表现为负值,正地闪强度较强,极易威胁民众生命财产安全。据此,提出一些有效的防雷减灾措施,供相关人员参考。
This paper selects statistical data on thunderstorm days,lightning frequency and intensity observation data from 2014 to 2022 in Hulunbuir city,and focuses on using mathematical statistical methods such as climate tendency rate to analyze the lightning activity patterns in Hulunbuir city in recent years.The results indicate that the frequency of thunderstorms in this region is relatively high,with an average of 131.1 thunderstorm days from 2014 to 2022,and a significant increasing trend at a rate of 38.5 days per decade.The total ground flash intensity is negative,while the positive ground flash intensity is strong and can easily threaten the safety of people’s lives and property.Based on this,several effective lightning protection and disaster reduction measures are proposed for reference by relevant personnel.
