在这项工作中，使用全球闪电定位网络9年的闪电数据研究了日本多次雷击（MSL）的气候学。本研究定义的各类闪电的MSL比率为14.1%，海洋上的MSL比率大于大陆上的MSL比率。平均多重数为2.58，海洋大于大陆。在温度为−20°C的高度，第一次和第二次冲程之间的平均冲程间隔较长，对应于较高负电荷区域的上边界。
In this work, the climatology of multiple‐stroke lightning (MSL) in Japan was studied using the World Wide Lightning Location Network's lightning data over a 9‐year period. The MSL ratio defined in this study for all types of lightning was 14.1%, and it was larger over the ocean than that over the continent. The mean multiplicity was 2.58 and was also larger over the ocean than that over the continent. The mean interstroke interval between the first and second strokes was longer for a height at which the temperature was −20°C, corresponding to the upper boundary of the higher negative charge area.
