It was great to give an overview of my research so far at the RMetS Early Career conference earlier today! And great to hear about the variety of other research from early career scientists in the field.

Very pleased to have won the Malcolm Walker Award for New Environmental Researchers! It is an honour to stand in the company of previous winners and it was great to attend the awards ceremony on Wednesday alongside the winners of other RMetS awards.

Anger as Dorset estate withdraws public entry to ‘stunning’ local landmark Visitors lament ‘tremendous shame’ as notice withdrawing public access appears after £30m sale of Bridehead Estate

I have good memories of cycling to here as a teen. It's a shame if future generations won't be able to do the same.

THE RISE OF MACHINE LEARNING IN CLIMATE MODELLING Very pleased to report the first published output from the @metoffice.bsky.social new team Data Driven Climate Modelling team. A short commentary from my esteemed colleague George Jordan rmets.onlinelibrary.wiley.com/doi/10.1002/...

Maps illustrating the Hydrological Summary for March 2025.

💧Latest Hydrological Summary shows:
-Below-average March rainfall in all areas of UK after dry winter
-Many rivers in N & W have exceptionally low flows
-Record low March groundwater levels in N Ireland, Scotland, Wales

"Why are you so bent out of shape, polar vortex?"

Beautiful view via earth.nullschool.net (using NOAA's free GFS model data) of the current stratospheric warming event – likely to be the final stratospheric warming (FSW) – featuring one of the largest stratospheric wave-1 disturbances on record.

Thanks! Essentially - although I'm getting the ferry from the Netherlands (near Rotterdam) to the UK (Essex)! The Eurostar essentially doesn't allow non-folded bikes, plus it's a 1.5 day trip and the overnight ferry with a cabin is more economic than a hotel somewhere :)

Bicycle with loaded panniers and a large backpack rested on it. On a train platform.

Yesterday was my last day at MPI-M, this morning I left Hamburg. It has been a great experience to live and work abroad and there's a lot I'll miss, but I'm also looking forward to what's next!

I really cannot believe my childhood career dream might end like this. Feeling so small and lost.

Met Office delivers £56 billion of economic value to the UK A new independent economic study has concluded that the Met Office will deliver benefits worth £56 billion to the UK economy over the next ten years.

Reposting this report, which has a message which I suspect holds true in many other countries.

RMetS Annual Weather and Climate Conference 2025 banner

What better way to spend three days in July than by coming to Manchester for this year's @rmets.org Annual Weather and Climate Conference? 😁

Please consider submitting an abstract – deadline 14 February.

We look forward to seeing you there! More details: www.rmets.org/annualconfer...

Visited Sylt at the very northern end of Germany yesterday. Only accessible from mainland Germany by train, with lots of unique landscapes and nice to see the sea!

Excited to say that I'll be starting a Scientist role in the Monthly-to-Decadal team at the Met Office in March! I will miss Hamburg and it's been a great experience to live and work in Germany, but I'm also looking forward to being back in Exeter/Devon.

LinkedIn post from Andrew Ng: "Just released: New AI Climate Simulator that you can play with. Visualize how geoengineering can slow global warming. There is no longer any path to limiting warming to 1.5 degrees Celsius (Paris Agreement), unless we use geoengineering. Reflecting 1% of sunlight away from earth would lead to an extra ~1 degree of cooling. Our simulator lets you explore how geoengineering via Stratospheric Aerosol Injection (SAI) gives us new paths to keep warming to 1.5 degrees. I think SAI is a promising technology worth serious exploration. Check out the simulator here: planetparasol.ai"

I worry that the concept of geoengineering is increasingly going to enter public discussion, not through climate scientists who want to make the nuances and ethics clear, but through the large audience tech sector who want to be seen as having solutions.

I think this issue is what leads to AI forecasts being billed as a replacement for NWP in some circles, as it's seen as something more advanced and sophisticated, whereas I think it's better seen as something that will supplement NWP for forecasting.

At some point the NWP world has to address that 'we run a statistical model based on what happened in the past to estimate the future' became the futuristic tech-y solution instead of 'we use the world's most powerful computers to represent the earth based on physics and then run it forward in time'

Princetown national park visitor centre to close THE POPULAR Dartmoor National Park visitor centre in Princetown is due to close after a funding injection ends in March causing concern the economy of the village will be affected.

Dartmoor visitor centre to close as National Park Authority cannot afford to renew lease from Duchy

National Parks are facing 12% budget cuts - not a great way for Labour to celebrate the 75th anniversary of their creation

& why is Duchy charging at all?

ENSO affects the North Atlantic Oscillation 1 year later We demonstrate a 1-year lagged extratropical response to the El Niño–Southern Oscillation (ENSO) in observational analyses and climate models. The response maps onto the Arctic Oscillation and is stro...

Pleased to have played a role in this work: the 1 year-lagged impact of ENSO in the extratropics far exceeds the expected effect due to ENSO autocorrelation, and we propose large-scale atmospheric angular momentum anomalies propagating polewards as a mechanism.

Extraordinary rainfall distribution in UK in September. Bedfordshire and Oxfordshire saw their wettest month in our 188 year series. But only 25% wetter than average overall despite many areas having 3x average rainfall. More details in Met Office press release www.metoffice.gov.uk/about-us/new...

New paper, led by Yingfei Fang during her visit to the University of Exeter: ENSO teleconnections to the South Pacific are underestimated in CMIP6 models, and are generally too far west although the position improves with increased ocean resolution.

Also had time to visit some Devon classics, including the coast path (Budleigh–Sidmouth, plugging a gap in my longest contiguous stretch), Dartmoor (for a wild camp) and Woodbury Common

It was nice to be at the Met Office (and University of Exeter) last week, with lots of useful discussions on climate prediction research.

Featuring some grey sky for bluesky, to prove once and for all that the Met Office aren't choosing their weather.
