That’s a wrap on our inaugural 2nd-year @earthscista.bsky.social undergraduate field trip to the Lake District!

We were blessed with predominantly glorious weather ☀️ which made measuring water quality & transport, carbon flux and boundary layer properties all the more fun 😁

I’ve been wondering this too, especially given other forecasts are shown wrt 1993–2016 hindcast climo

Last meetings with undergraduate BSc dissertation students before they hand in next week! Always a joy to see their progress – from me explaining things to them at first, to them explaining things to me by the end. Some really exciting research in there, too!

Final prep underway for our inaugural 2nd-year undergrad Environmental Earth Science field trip to the Lake District next week! @earthscista.bsky.social

We'll be exploring boundary layer meteorology, soil erosion, nutrient transport, water quality & carbon flux. Hoping the weather is on our side...

Awesome example of a density current/cold pool propagating south away from main cold front precipitation (itself with SW flow but progressing SE) across Scotland this evening.

The cold pool is intense: temperature at Leuchars (near St Andrews) fell from 11.5°C to 5.1°C in 30 mins.

Of course there are occasions when this has good reason, but if you've accepted a review request and know you'll be late, just email the editor. If you know you can no longer do the review due to other commitments, just email the editor. They will be grateful!

No doubt that peer review is creaking under its own weight, but in my experience as an Editor and as an author, one thing that always causes delays is reviewers who accept an invitation, and then go AWOL with no communication with the journal.

There is this psl.noaa.gov/data/atmoswr... but it doesn’t have an equivalence (yet) for all PSL’s tools (e.g. daily data, correlations)

Yes, agreed. It does seem like PSL’s plotting tools haven’t been ported over to using CORe though

NCEP's R1 reanalysis was extremely old (Kalnay et al. 1996) and had myriad issues, but terminating it with about a month's formal notice such that other derived datasets go offline is yet another blow to US-led climate science.

I was thinking about this when the article mentioned (very briefly) the far greater Scottish land access rights. Not that I think something similar is possible in England, but the difference is pretty stark.

A fantastic day at Cambo House for our School's Postgraduate Research Away Day – a beautiful setting for science, sunshine, and smiles.

Excellent to see all our research students presenting their work through talks and posters, showcasing a great standard of diverse research.

Well done all! ⭐

A fantastic view of #StormTherese #BorrascaTherese this morning over the nearby Atlantic and, as MeteoGib has been flagging up, responsible for driving further dust across Iberia - giving hazier skies and dusty rain with any showers/rain.

Can AI models reliably forecast extreme weather events? More-rigorous testing is required before artificial-intelligence approaches are widely adopted by public forecasting agencies.

The authors of a Comment article in Nature highlight concerns over adopting AI in meteorology and call on the weather and climate community to set clear standards, starting with agreed data sets, for testing out-of-sample extreme-event predictions objectively. 🧪

I've also reviewed (single blind) where it's been glaringly apparent that the supervisor's input must have been, let's say, minimal, and that outsources their work to me. Which led to a poor experience for everyone involved.

The number of review requests I'm receiving has skyrocketed lately for reasons I don't understand. I'm aware this is a widespread problem and somewhat scales with career stage but the abruptness with which this has increased for me is a bit startling – since of course I have to decline the majority

The forecast rainfall map within the Met Office app is a fantastic feature for understanding what the icons really refer to (even in the new app version which has been extremely poorly received).

'Misleading weather apps can cost attractions up to £137k a day' Chester Zoo is leading a call for a change in the way

This article only mentions the Met Office, but my experience suggests it’s Apple Weather and BBC Weather which far too easily/frequently set their icons to rain, even when the associated rainfall probability suggests it’s more likely to be dry www.bbc.co.uk/news/article...

A positive North Atlantic Oscillation is set to take charge of our weather in the coming days - but what does that actually mean? 🌬️ 🌦️
How will it shape the days ahead? and how long could it stick around?
Met Office meteorologist Aidan breaks it down in this week’s deep dive.
