In a new paper lead by Valentina Ortiz Guzmán we focus on impactful extreme weather. We define stalling cyclones as slow-moving rain-bearing midlatitude weather systems and find they occur most frequently close to the east coast of all continents. link.growkudos.com/1f94myyu58g 🧪

Global Hotspots of Stalling Extratropical Cyclones

This paper defines a "stalling" type of weather system. It is defined as extratropical cyclone which remains near-stationary and produces extreme rainfall. This definition selects weather systems whic...

In a new paper, I look at how temperature and precipitation from weather systems relate. Clausius Clapeyron (~7%/degree warming) seems often appropriate, but some places show twice as much precip increase with temperture. Snow and multi-day rainfall are different. 🧪 link.growkudos.com/1ecukqq5yio

Temperature scaling of rainfall from weather systems

Temperature regulates the amount of water vapour in the atmosphere. Clouds produce rainfall by converting water vapour into liquid rain drops, thus linking surface temperatures to rainfall amounts. Te...

An interesting start to April in the tropical western Pacific. 3 cyclones spinning off very close to each other, but in both hemispheres. Beautiful dynamics, powerful weather. Maila,Vaianu and Sinlaku. viz by myself, data from GFS.

Busy days around what might become to be known as the 2025 Sudden Stratospheric Warming: Loads of media interest, and thanks to the journalists who take their time to talk to me before writing their story. Happy to take some of mine in turn. theconversation.com/air-temperat...

wait, is there another typhoon following #Ragasa (1) and #Neoguri (2)?

Martin Jucker @drjucker.bsky.social · 23/09/2025

Super Typhoon #Ragasa definitely has an eye. Here seen from relatively low-resolution GFS data. But there’s also some wild dynamics happening all over the Pacific. #weather #sciviz

Martin Jucker @drjucker.bsky.social · 22/09/2025

Busy Western Pacific right now. Cat 5 (Ragasa) and 4 (Neoguri) not far from each other. I wonder whether the strong tropical Pacific activity could be linked to the unusually weak Antarctic stratospheric polar vortex at the same time? 🤔 #sciviz #Ragasa #Neoguri
