Great thread from Ed looking at how the Met Office data series for UK temperature stacks up against other reliable but independent measurements. Spoiler alert: very well indeed 🧪

Monitoring changes in UK temperature

To (almost) no-one’s surprise, multiple sources of data agree on the long-term trends in UK temperatures.

All the weather on the north edge of Dartmoor today. Played it safe with mostly lanes and field paths.
A moody sky above a valley of green and ploughed fields and hedges Black sky behind sunlit fields, rough hedge in foreground A bend in a wet lane with half rainbow above green sunlit fields Fingle Bridge , an ancient three arch bridge across a dark river with white riffles.  Set in a deep gorge brilliantly sunlit on the right side with blue sky above

They may do better than vague promises for an unknown future date though!

Noted: it will be made available eventually as we open all our data, but I can’t say exactly when or where yet

It will evolve from the remains of Humberto but strictly it’s a new system once it’s undergone extra-tropical transition and so it gets a new name

National Met Services don’t give warnings for each other’s countries because of respecting each other’s authoritative voice. When Met Eireann show warnings in the north they’re from the Met Office. Maps on our app do show whole of Ireland for rain etc.

Good: we’re experimenting with different ways to communicate uncertainty. Thanks for the feedback

Unsettled weather is on the way later this week - here's an overview ⤵️

Keeping an eye on the evolution of a deep low towards the weekend (again, sorry!)
Three scenarios for where we might see the strongest winds on a map of the UK. Most likely in Scotland but NI, Wales and West Midlands is scenario two and mostly north of Scotland is scenario three

One of those “Doh! Why didn’t we think of it earlier?” moments

Vertical rows are the agrivoltaic winner!

“The vertical panels produce slightly less electricity—but with higher value, as generation peaks coincide with morning and late afternoon demand…The crops don't seem to mind the presence of solar panels and they like the wind protection they provide.”
Double harvest: Vertical solar panels and crops thrive side by side
Imagine a field where solar panels and crops coexist—with no trade-off. It sounds like science fiction, but that's precisely what researchers from Aarhus University have now documented in a full-scale...

I was on the South Moor yesterday. This is the Teign Estuary from Horridge Common but the sea was visible all along to Plymouth
A view across a patchwork of fields and hedges framed in dark foliage. The silvery water of the Teign Estuary feeding into a blue grey sea with drifting grey clouds above

In a tent? A big storm could well have seven days of warning, but we’d be encouraging people to cancel their camping rather than book it. There’s no way to know weeks in advance when a storm might be though.

I had the same just after Covid when all waiting staff were new, with Viognier. Even after I pointed at it on the wine list, it arrived red.
