Study on the Thunderstorm Activities and Changes in the Northern Forest of Greater Khingan Mountains from 1971 to 2008
【摘要】 利用1971~2008年大兴安岭北部林区8个气象站气象观测资料,对大兴安岭北部林区雷暴的活动情况和变化规律及闪电空间分布、闪电的次数、强度和能量的活动情况等特点进行分析。结果表明:大兴安岭北部林区雷暴活动呈波动减少态势,其北部的满归、莫尔道嘎和乌玛等地是闪电频发的中心地带,闪电的强度和能量在6月中旬以后明显增强。
【Abstract】 Taking advantage of the northern forest of Greater Khingan Mountains eight meteorological observation stations meteorological data during 1971-2008,the thunderstorm activities and changes in the northern forest of Greater Khingan Mountains were analyzed,and the characteristics of lightning spatial distribution,lightning frequency,lightning intensity,lightning energy activities,etc were analyzed. The results of the analysis showed that:the northern forest of Greater Khingan Mountains thunderstorm activity is in less volatile trend,and Mangui,Mordaga,Uma,etc in the north of the northern forest of Greater Khingan Mountains are the center of frequent lightning,lightning intensity and energy significantly increase after mid June.
