Den ganzen Tag habe ich überlegt, wo der dichte "Rauch" im #Schächental herkommen könnte. Gerochen hat man nichts. Jetzt ist es klar: grösserer Felssturz in der Nordwand des Gross Ruchen heute am frühen Morgen: www.ur.ch/mmdirektione...

Projection has become reality 22 years ago, Christoph Schär et al. published a landmark paper in Nature explaining that the 2003 heatwave was a harbinger of things to come. The study featured an iconic figure - shown in countless lectures - illustrating how outlandish the event was at the time

⭐ We’re proud to see two exceptional Met Office colleagues recognised in this year’s @rmets.org Awards! These awards celebrate a breadth of work across the meteorological community, recognising excellence in research, education, communication and professional practice. Find out more below👇
"I'm delighted to receive the L F Richardson Award. It means a great deal to have work in applied science and user-focused meteorology recognised, as I am very passionate about translating scientific advances into practical applications that deliver real-world value. I am very grateful for the support of my colleagues across the Met Office, whose expertise and encouragement have been invaluable."
Alice Lake
Post-Processing Senior Scientist"I am deeply honoured to receive the FitzRoy Award for Professional Meteorology. Enabling sustained access to satellite observations includes enormous collaboration and support from so many colleagues in the Met Office, across the UK space community and internationally. To have that collective effort recognised means a great deal to me and I hope it shows that there are many valuable ways to contribute to our field."
