New findings from Newcastle University show that climate change is reshaping the nature of severe hail, with significant consequences across the continent.

Our climate experts have discovered that climate change is supercharging Europe’s biggest hail. Study findings revealed that global warming may lead to less frequent but bigger and more devastating hail storms. 🌩 Find out more here. ⬇ https://t.co/BH6TNktfbI

Our study on future decrease in European severe hail is now published at @NatureComms. Very large hail remains a threat, due to size distribution changes and the emergence of a new, warmer thunderstorm cluster especially in Mediterranean countries.

🌊 Today in @Nature: Is the AMOC on the brink of collapse? Unlikely before 2100—but the risks are real 🚨 We find Southern Ocean winds keep this vital ocean “heat engine” running, even under extreme #climatechange. But the Pacific holds a surprise… Let’s explore 🧵👇

Jet stream, extreme weather, and climate change. I'm one the scientists interviewed for this week's issue of @newscientist
Global warming seems to be blocking the jet stream, keeping weather patterns stuck in place, with dire consequences, including wildfires and flash floods. We urgently need to know what’s going on.

So sad to learn that Chuck Doswell has passed. He was probably the most inspiring severe storm scientist ever.

I have commented on the earlier desert hailstorm in Saudi Arabia.
science.feedback.org
In early November, several photos were shared via social media and news outlets showing what was allegedly the ‘first-ever snowfall on record’ in the Al-Jouf (or Al-Jawf) desert in Saudi Arabia. This...

The upper row shows the proxy for intense storms: present climate, future climate, and normalized change from left to right. The below shows a tiny fraction of these intense storms, the "almost stationary" ones.

When the thunderstorm system is slow, or stationary, all of the rain falls down to a small area. If the storm is well organized, it is long-living. And finally, if there is a city underneath, then it is a disaster.

It is not only the intensity of rain, but the persistence is what makes the devastating outcome. Convective rain is intense almost all the time, but the thunderstorm cell(s) move fast: hence a locality experiences the worst for a limited duration (of minutes).

Up to 400 kg/m2 rain in less than 12 hours is observed. One can compare this with the annual rain totals in a central European city.

The recent flood in Spain is caused by a Mediterranean thunderstorm phenomenon that inspired "Quasi-Stationary Intense Rainstorms" study. These occur in the south every few years, and are catastrophic. Is the rest of Europe ready for them?

Devastating floods in parts of #Spain after year's worth of rain fell in less than 24 hours. The animation below from #MTGI1 clearly shows large thunderstorms with strong lightning activity, causing exceptional rainfall and flash floods between 00:00 UTC yesterday - 10:00 today.
