Antalya'daki hortum felaketi... Şekil 2020 yılında Abdullah Kahraman (@meteogreen) hoca ve Deniz Ural'la yayınladığımız makaleden...
Makalede, konvektif yağış faktörünü de ekleyerek, şiddetli fırtınalara ve süper hücrelere yol açması beklenen -hortumlara da neden olabilecek- şartların oluştuğu günleri bir indeks kullarak hem günümüz hem de gelecek için iklimi değişikliği simülasyonları yardımıyla hesapladık. Sonuçlar Türkiye için özellik de Akdeniz kıylarımız için çarpıcıydı. Türkiye’nin güneybatı kıyılarında yılda 10-14 güne varan artışlar belirlendi... Özellikle de sonbahar mevsimi için!
Bugün yaşanan aşırı hava olaylarında insan kaynaklı iklim değişikliğinin katkısı var mı? Muhtemelen var, gözlemler ve modellerden üretilen bilgiler bunu doğruluyor. Peki biz bu bilgilerle ne yapıyoruz? Tahmin ve izleme sistemlerini kullanıyor muyuz? Değişime uygun stratejiler geliştiriyor muyuz? Ve bence en önemlisi, nasıl bir geleceğe uyum sağlayacağımız farkında mıyız? Sayısal olarak!
Yoksa yine büyük otellerdeki "iklimlendirilmiş " toplantılarda az kalan değerli zamanımızı mı tüketiyoruz?...

I've commented on a recent attribution study.
A violent hailstorm that slammed Paris last year caused more than $350 million in damage. Now scientists say they can see how climate warming likely intensified that specific storm by boosting the energy that helps hail grow.

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. 🌩

One of our top-rated articles on @altmetric this past week was published open access in @NatureComms. Read 'Future changes in severe hail across Europe, including regional emergence of warm-type thunderstorms' here: nature.com/articles/s41467-0…
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. doi.org/10.1038/s41467-025-6…

🌊 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…

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. newscientist.com/article/mg2…
So sad to learn that Chuck Doswell has passed. He was probably the most inspiring severe storm scientist ever.

I have PhD projects live on flood-cdt.ac.uk/ I am involved in supervising: "A sub-hourly quality controlled blended UK precipitation dataset to understand uncertainty in flood predictions" and "Understanding Record Breaking Flood Events"
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).
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.
