According to multiple reports, a wildfire in southwest France has grown so intense that it created its own weather system. The phenomenon, known as a pyrocumulonimbus cloud (pyroCb), generated lightning that ignited additional fires beyond the original blaze.
Key Takeaways
A wildfire in southwest France generated a rare pyrocumulonimbus cloud, creating its own weather system with lightning that sparked new fires. The blaze has burned over 420 square kilometers, destroyed more than 240 homes, and forced 220,000 evacuations.
- Wildfire near Saumos created France's first recorded pyrocumulonimbus cloud
- Lightning from the cloud ignited new fires beyond the original blaze
- Over 420 square kilometers burned, 240+ homes damaged or destroyed
- 220,000 people evacuated in Gironde department
Source Claims Check
High Consensus| Claim | Status | Reason | |
|---|---|---|---|
| Pyrocumulonimbus Cloud Formation | Broad Agreement | Hot air loaded with smoke rises, cools and forms ice crystals that separate electrical charges. | |
| Fire Impact On Gironde Department | Broad Agreement | Over 420 square kilometers burned, more than 240 homes damaged or destroyed. | |
| Evacuations In Gironde | Broad Agreement | 220,000 people evacuated. |
The fire began near Saumos on July 22 and has since burned more than 420 square kilometers of forests and scrubland. It damaged or destroyed over 240 homes, forcing 220,000 people to evacuate in the Gironde department as reported by TimesLIVE.
Theodore M Giannaros, a fire meteorologist at the National Observatory of Athens explained that this phenomenon is rare in Europe and more commonly documented in North America and Australia. The cloud formed around 6:20 PM on Friday, two days after the fire began, according to France's national firefighters federation.
The pyrocumulonimbus cloud creates a feedback loop where rising air pulls powerful winds toward the fire while downdrafts punch gusts back to the surface. This makes the fire harder to predict and control as reported by Los Angeles Times. The cloud can also spin up whirling columns of flame, known as fire whirls.
The European continent is heating faster than any other on Earth, with heat waves growing more frequent and severe according to the EU's Copernicus Climate Change Service. This creates hotter and drier conditions that give extreme fires more opportunity to form such weather phenomena.
