Can AI weather models forecast UK windstorms well enough to be used when providing wind weather warnings? We found that they are not yet suitable to replace current NWP models, particularly when strong winds are linked to sharp fronts & smaller features. Preprint: essopenarchive.org/doi/full/10....

Following the withdrawal of funding by UKRI-NERC, we can confirm that the FAAM Airborne Laboratory will cease operations at the end of this financial year. Our immediate priority is supporting affected staff and the wider UK atmospheric science community. ncas.ac.uk/closure-of-t...

Interested in revealing how moisture-driven surface cyclones can develop into hazardous windstorms, now and in the future? You could do it at @unirdg-met.bsky.social @ncas-uk.bsky.social, working with @benharvey.bsky.social, @jriboldi.bsky.social, Sue gray and me! jobs.reading.ac.uk/Job/JobDetai...

Are you investigating the role of "Diabatic processes across scales in the extratropics"?this? Do you want to know more about it? There's a workshop for you! diabatics2026.w.uib.no We have a great invited speakers line-up (despite me being one...). Deadline for abstract submission is tomorrow!

This morning Sue Gray presented our work producing the first global climatology of sting-jet extratropical cyclones: wcd.copernicus.org/articles/5/1.... Using ERA5 we analysed ~10k top intensity 1979-2022 cyclones and looked for cloud-head mesoscale instability as a proxy of sting-jet activity

A global climatology of sting-jet extratropical cyclones

Abstract. Sting jets have been identified in the most damaging extratropical cyclones impacting northwest Europe. Unlike the cold conveyor belt and other long-lived cyclone wind jets, sting jets can l...

Beautiful frosty sunrise this morning on the Gurten, above the freezing fog in Bern and with great views towards the Jungfrau group. A great start for the first day of the 10th European Storm Workshop!

Storm Éowyn developed through a process called explosive cyclogenesis This brought the UK's highest wind gust of the season so far on Friday with 100mph gusts at Drumalbin in South Lanarkshire This view from space shows how the storm developed 👇

We've put together a little explainer on Storm Éowyn, its development, where it stands compared to other (in)famous storms and on whether future explosive cyclones could become more "sting-jetty" and diabatically driven theconversation.com/why-meteorol... @ncas-uk.bsky.social

Why meteorologists are comparing Storm Éowyn to a bomb

Éowyn’s wind speeds are comparable with the most infamous storms of recent years and decades.

Worth stressing that while storm structure, intensity, sat imagery & gust timing/location are all consistent w/ sting-jet descent, we don't know yet if it reached the ground & caused the W Ireland record gusts. The cold conveyor belt might have had a role & is responsible for the gusts over Scotland

WOW! The sting jet is about to hit Galway! See the pointy cloud? That’s the “stinger” as seen in @myradar.bsky.social! Shannon Airport has already gusted to 78 mph; Dublin has gusted to 60 mph. Galway should be ready for winds gusting 90-100 mph over the next few hours. #StormEowyn

The intensity & structure of #StormÉowyn were certainly conducive to sting-jet descent. This satellite image would be consistent with it, as would be the timing and location of the record gust. However, we can't yet say whether the cold conveyor belt also played a role there 1/2

Storm #Éowyn has set new wind speed records for Ireland as potential sting jet hits the west coast (mean wind 37.5 m/s & gust 50.8 m/s). The location of the maximum winds and the satellite appearance of #Éowyn match with the conceptual model of a sting jet.

Storm Bert is set to hit the UK on Saturday, bringing strong winds, snow and rain. We spoke to Ambrogio Volonté, Senior Research Fellow at @ncas-uk.bsky.social and the University of Reading, about named storms, and found out what has been causing the cold weather. ncas.ac.uk/scientist-ex...
