文山州短时强降水和雷电时空特征分析
|
摘要
利用文山州2008～2017年闪电定位数据和100个观测站点2012～2018年小时降雨量观测资料对文山州短时强降水和雷电的时间和空间分布特征进行分析。分析结果表明:文山州短时强降水和雷电夏季(6月-8月)比较活跃,最强时段分别出现在5月和9月;短时强降水和雷电均在午后至夜间较为活跃,短时强降水高发时段较雷电推迟1～2小时。空间分布特征表现为:短时强降水在中部以南地区较活跃,特别是西南部和东南部,年均出现10次以上;雷电强度和密度空间分布不一致,西部雷电高发但强度不大,东部为雷电低发区,但强度较大。
The spatial and temporal distributions of short-time heavy rainfall and lightning activities have been analyzed based on the lightning data from 2008 to 2017 and the hourly precipitation data of 100 w eather stations from 2012 to 2018 in Wenshan. The results indicate that the short-term heavy rainfall and lightning activity w ere more active in summer( from June to August),and the strongest periods w ere in M ay and September respectively. Both short-term heavy rainfall and lightning activities w ere more active from afternoon to night,The period of high frequency of short-term heavy precipitation is 1 ～ 2 hours after the lightning activity. The spatial distribution features are as follow s: short-term heavy precipitation is more active from central to southern,especially in southw est and southeast regions,more than 10 times/a. The spatial distribution of lightning intensity and density is not consistent. Lightning occurs frequently but not strongly in w est,But the distribution is the opposite in the east.
