Aug 8, 2022 · Scientists have identified the weather conditions that create dry lightning, which starts California's most devastating wildfires. These conditions can be modelled over the long term to...
Jun 6, 2023 · Lightning strikes from dry thunderstorms are particularly hazardous in the West because they can ignite wildfires since no rain is wetting the vegetation below. The dry fuels are a prime source...
Sep 19, 2023 · Dry lightning can still be disastrous even when conditions aren't so dry, a study has found. These cloud-to-ground strikes during little to no rainfall were previously thought to pose wildfire danger only if occurring with less than 2.5 mm of rain in a day (about 0.10 inches).
Sep 17, 2021 · The fire risk depends on weather conditions before and after a dry thunderstorm. If soils are dry, there’s a higher chance that dry lightning could spark a wildfire. The odds are lower if recent rains have dampened the vegetation.
Jun 17, 2024 · But climate change is making the weather conditions needed for wildfires to spread more likely, the IPCC says. Extreme, long-lasting heat draws more moisture out of soils and vegetation.
