法国西南部吉伦特省一场强烈野火在7月22日于Saumos地区爆发，火势之猛烈足以产生热积雨云现象1。这种罕见的气象现象由野火产生的热量驱动，云层内部的闪电击中地面并引发了新的火灾1。
截至报道时，该野火已烧毁超过420平方公里的森林和灌木地，摧毁或损毁超过240所房屋1。灾情之严重致使吉伦特省22万人被迫撤离1。部门消防和救援服务在7月24日下午6:20左右确认了这一热积雨云的形成1。
法国国家消防员联合会指出，这是该国有记录以来首次观测到此现象1。相比之下，加拿大在2023年就记录了142起热积雨云事件1，而欧洲大陆自1980年代以来以全球平均水平的两倍速度升温1。
A major wildfire that erupted near Saumos in southwestern France on July 22 produced a pyrocumulus cloud—a rare phenomenon in which intense heat generates towering storm clouds capable of producing lightning that strikes the ground and ignites new fires.1 The France National Federation of Firefighters confirmed this marked the first time such a phenomenon had been recorded in the country.1
The blaze has devastated vast tracts of land across the Gironde region, consuming more than 420 square kilometers of forest and scrubland while destroying or damaging over 240 homes.1 The fire forced approximately 220,000 residents of Gironde to evacuate their homes.1 On July 24 at approximately 6:20 p.m., departmental fire and rescue services officially documented the formation of the pyrocumulus cloud.1
The extreme conditions enabling such a phenomenon reflect broader climate trends, as continental Europe has warmed at twice the global average rate since the 1980s.1 While such fire-generated clouds remain uncommon in France, Canada recorded 142 instances of pyrocumulus clouds in 2023.1
