Abstract Lightning is the most important natural wildfire ignition source worldwide. However, identifying the specific lightning causing a forest fire is a challenging task. The goal of this study is to understand how different methodological approaches affect the association between igniting lightning and natural fires. To this purpose, we combined data on 267 lightning-caused forest fires from Switzerland with data on cloud-to-ground lightning strokes for the period 2000–2018. We searched for the most probable igniting lightning (candidate) among all lightning that occur during the days (up to two weeks) before fire detection in the vicinity (

阿尔卑斯山的闪电引起的火灾：识别点火中风

摘要 闪电是世界范围内最重要的自然野火点火源。然而，识别导致森林火灾的特定闪电是一项具有挑战性的任务。本研究的目的是了解不同的方法学方法如何影响点燃闪电和自然火灾之间的关联。为此，我们将来自瑞士的 267 起闪电引起的森林火灾的数据与 2000 年至 2018 年期间的云对地雷击数据相结合。我们在附近火灾检测前几天（最多两周）发生的所有闪电中搜索了最有可能点燃的闪电（候选）（
