Thank you for another amazing deep dive Aidan! I always enjoy your explanations of how our weather works as it has made me more knowledgeable and I'm learning all the time. I never knew that temperatures at 5000 feet can be higher than surface temperatures. The Foehn effect explanation was amazing too. I love these deep dives thank you to you and everyone at the Met Office team for inspiring me to be passionate about all things weather!
That was an excellent description of soundings, the foehn and lee wave effect. I have many times flown in a glider up to at least 10 times the height of the up wind hills.
Thanks Aidan and team! Another great insight. I love these in-depth breakdowns, keep them coming! It's nice to know the theory behind weather patterns and their behaviour 😃
Cheers Aiden and all the team behind the scenes which make these deep dives and 10 day forecast. I throughly enjoy the deep dives where you go into detail about our weather. Keep up the amazing work to all , take care . Stevie from Glasgow
Hi audan great to see weather stuido liv is back get Aidan can we bring back mid morning video on the met office youtbe channel remember before covid we had it please bring it back
I lived in Christchurch New Zealand for a year and we would experience 'Nor-Westers' (Foehn effect). These were strong and extremely hot winds. Obviously the Southern Alps are considerably higher than the Scottish Highlands where I now live. By the way the afternoon was fine and sunny.
As you can imagine in a climate with prevailing south westerly winds the NE of Scotland benefits greatly from the Foehn effect, it keeps the region significantly drier than the rest of Scotland, Aberdeen gets less rain per annum than many locations even on the south coast of England and also a fair bit sunnier than the rest of Scotland, despite Aberdeens gloomy reputation. When you watch weather fronts crossing Scotland you can often see them fizzle out as they cross the mountains leaving Aberdeenshire dry.
The problem with this weather is it's very much a 'dunkelflaute' period where both both wind and solar energy generation is very low meaning we have to resort to burning epic quantities of gas to keep the lights on.
This is the worst ‘high’ pressure system I’ve ever witnessed in the UK. I’d rather -10°C but sunny at this point as I haven’t seen the sun for two weeks now!
@@Notasmurf-vw6toNorthern Ireland has been extremely dull!! I don’t think I’ve seen the sun for over 2 weeks either. I was in the Mourne’s last week and there was very little sun.
Great info as always. Saw all of this first hand this morning on flight from Tenerife into Bristol, we were told all devices off as it was going to be an autopilot landing, flying into Bristol. The cloud was just this thick sludge over what seemed the entirety of North France and South West UK, coming down through it, the cloud at Bristol was pretty much on the runway.
An excellent and very interesting lesson about the Foehn effect Aidan! We came away for a few days to the New Forest for some autumnal photos of autumn, but... that didn't exactly work out with the misty weather, and, needs to say, worse than that tomorrow after the fireworks earlier tonight. Anyway, I thoroughly enjoyed the lesson all about the Foehn affect, brilliant. Very many thanks Aidan, and to the Met Office. I can't wait til Friday at 12.15 to see what Alex is up to, time will tell. 😂😂 Take care everyone
Thanks for the detailed information Adian, last saw the sun for about an hour or 2 on Wednesday last week. Hopefully I’ll see it again soon as much as I don’t mind no rain and I would love some winter sunshine.
Really good explanation of the foehn effect, adiabatic lapse rates and other quite complex concepts presented in an easy to understand fashion. Well done. Obviously a lot of preparation gone into this.
Good in depth explanation of the Foehn effect. Not often our weather is this unchanging. The 5th of November is Guy Fawkes, it should never be forgot according to the rhyme.
I don't think you need a 3rd camera. Ideally a blue screen you could interact with, but I that technology exists. Outstanding video as always. Love your work
Great deep dive again Aiden ❤ Always informative and great detail into our weather . Look forward to live on Friday ! But what time will it be live please as I am on a short week but got a village meeting at 6.pm I hope I’m not going to miss it 😢
Crazy to think just a few thousand feet above us there's perfect high pressure conditions that'd put an average May day to shame... I've never done a mountain summit before, but needs must for the vitamin D
We wait for a lovely long lasting high pressure area to arrive all summer, it does but in autumn and give us the worst cloudy moody weather. Can you tell it to hurry up and clear off Aidan, its pushing my electricity prices up lol
Is it harder to predict the cloud cover when the weather is like this? I’ve noticed the app has been wrong a few times promising some gaps in the cloud which sadly haven’t materialised 😢
You don't want to have that water land on you, though - closest I ever came to drowning on dry land, I was forced to walk bent double with my hands to each side of my mouth to create an air space to breathe in.
Part of the reason is the Madden Julian Oscillation (MJO). See last week's Deep Dive for a full explanation. Essentially, this is a regular increase in the activity of thunderstorms in the tropical Pacific that can have consequences on all sorts of global weather patterns, primarily due to the way that it causes the jet stream to become more amplified. So, one consequence for the UK is an increased chance of high pressure. It's unlikely to be the only reason we've got high pressure at the moment but it has increased the chance of it. The influence of the MJO in the summer is much weaker, with other things affecting the UK's weather (global heatwave distribution, sea surface temperatures etc). The reason the influence is weaker in the summer is because the winter stratospheric polar vortex hasn't formed and that can act as the common thread. In other words, you can have a summer dominated by low pressure for various reasons and then, once the stratospheric polar vortex forms in the autumn, other factors can come into play and switch up our prevailing weather patterns.
No. Weather systems are not very deterministic; they do not have a direct cause or purpose, nor do they perfectly align with the solar seasons. There are trends, such as the air pressure during summer in the UK is generally higher leading to less rainfall, but even that is an overgeneralization, and everything is under the influence of the butterfly effect. Places where the weather systems align more closely with seasonal changes include areas with monsoons (near the equator) or Mediterranean climates (they have a wet winter and a distinctively dry summer), but there are always anomalies, like what we're experiencing at the moment. EDIT: The MJO plays a role like Exeter said, but once again, the MJO being amplified is not causally sufficient to guarantee any specific weather pattern, it just boosts the probability of certain patterns.
Gosh you have so many knobs too press, you must get tired, have a rest, you try so hard to do your best, but out here watching it becomes a pest, the hand set that normally you use was quicker, just as well you are not thicker, but with all these knobs you must get confused! Don't you think you are being used? but all these knobs put's you up to the test, at the end of your shift, your wee finger must be bruised!
Love the indepth explanation huge thank you. You fired my interest and I found this guy m.ruclips.net/p/PLCewapt2D7PsD6fL3KkNInBYCQHLZuGoM who very patiently explains from basic principles. Has some great examples based around seemingly less complex New Mexico weather.
Is it harder to predict the cloud cover when the weather is like this? I’ve noticed the app has been wrong a few times promising some gaps in the cloud which sadly haven’t materialised 😢
Yes, it's much harder. The layer of cloud is relatively thin, low and tenuous moved on by light winds so the computer models struggle much more with it compared with large weather fronts or depressions.
Thank you for another amazing deep dive Aidan! I always enjoy your explanations of how our weather works as it has made me more knowledgeable and I'm learning all the time.

Also, thank you for bringing back weather studio live streams.
We are excited to be back!
Wow what a teacher amazing explanation.
Great deep dive. Landing into Heathrow this morning, very smooth air, 17c at 3000ft and 11c on the ground!
That was brilliant. Thank you for the deep dive. As a pilot, it has been so valuable.
Aiden, thanks for a great explanation yet again, you make these deep dives interesting and well worth viewing, much appreciated.
Outstanding explanation of complex met phenomenon - thank you!
Thanks, Aidan; no bonfires of any kind allowed in the US right now as we are 85% in some level of drought. Cheers🎉
That was an excellent Deep Dive - loved the detailed explanations. Well done.
Like the description of the atmospheric sounding taken above our heads.
The mountain tops have been brilliantly clear

Adiabatic - a new word to amaze my work mates🤣 Brilliant! Why would you go live on a Friday afternoon when the majority of us are at work????
Yes, I'm gutted as I'm at work on Friday. D'oh!!!!
Thank you
Fed up with the gloom now, I can barely tell it's daytime. Looking forward to the live studio though...😁
looking forward to the live ☁
This is the worst ‘high’ pressure system I’ve ever witnessed in the UK. I’d rather -10°C but sunny at this point as I haven’t seen the sun for two weeks now!
I’m in Northern Ireland Btw
We haven’t seen the sun for 6 months ( Dumfries & Galloway)
@@Notasmurf-vw6toNorthern Ireland has been extremely dull!! I don’t think I’ve seen the sun for over 2 weeks either. I was in the Mourne’s last week and there was very little sun.
@bluebear904 ay, I love ur content
-10?? I'm enjoying not having the heating on.
I really look forward to these, so relaxing at bedtime...thank you 😊
Brilliant explanation Aiden, thank you.
I love those tephigrams. It brings the thermodynamics of the atmosphere to life.
Fantastic.
Really interesting. Thank you
Excellent deep dive, I am very glad you are not trying to fit within 20-30 min and go straight to the nerdy stuff. Superb explanation!
Great stuff!
i live in ireland and there has been no sun for 8 days 0 thanks adian

The best deep dive ever. Amazing stuff

Another excellent Deep Dive. Thanks.
Fascinating; thanks for the in-depth look at the changes in weather over the mountains.😀
Good in depth explanation of the Foehn effect. Not often our weather is this unchanging. The 5th of November is Guy Fawkes, it should never be forgot according to the rhyme.
Like the mild weather but this cloud is so depressing… help
If you live in Aberdeen and Aberdeenshire the Foehn effect is one of the most significant climate factors in the region.
Best explanation of that I've seen!
i feel like i just signed up for a university course .....sign me up!!! shades of open university late at night as a kid, love it.
I don't think you need a 3rd camera. Ideally a blue screen you could interact with, but I that technology exists.
Outstanding video as always. Love your work
Interesting and good explanations, thanks. JC
Brilliant video, clean explanations… keep it up please 😁
These are so good. I remember some from geography, but a great refresh of foehn effect etc.
Great deep dive again Aiden ❤
Always informative and great detail into our weather .
Look forward to live on Friday ! But what time will it be live please as I am on a short week but got a village meeting at
6.pm I hope I’m not going to miss it 😢
Very good.
Another cracking deep dive by Aidan following on from one last week, Where can I find contemporary tephigrams online?
Crazy to think just a few thousand feet above us there's perfect high pressure conditions that'd put an average May day to shame... I've never done a mountain summit before, but needs must for the vitamin D
Very nice! Hopefully Paris is good for 18-22nd as I'm going on a trip there
We wait for a lovely long lasting high pressure area to arrive all summer, it does but in autumn and give us the worst cloudy moody weather. Can you tell it to hurry up and clear off Aidan, its pushing my electricity prices up lol
Two days of fog in Jersey and only three flights landed!
Drizzle in merseyside this afternoon.
That was very interesting.
I'm thankful we're not like Spain. At least I enjoyed a lovely walk without a coat!

Wow I think this way above my brain understanding 😂 I’m trying really 😉
11th October is past is this for next year?
Hope there's not an exam at the end of this as I don't fancy my chances.
We are in autumn now summer has gone
Groundhog day for most of North Western Europe
Fog helped along by bonfire smoke? I don't think so.
Is there an "in a nutshell" answer to this question: why prolonged anticyclonic weather over/near us in Oct/Nov 2024, but hardly at all in Summer 24?

1 can can u find the coldest and hottest place on your fancy map
If we get the beast from the east Aiden will you be swapping back to the left side of the screen as before.
This camera angle kinda makes me dizzy and sicky 😢🤢 in the opening i mean 😂
Gosh you have so many knobs too press, you must get tired, have a rest, you try so hard to do your best, but out here watching it becomes a pest, the hand set that normally you use was quicker, just as well you are not thicker, but with all these knobs you must get confused!

Not liking this dull grey weather much its depressing.

😂😂 amazing people thank MET Office, well i suppose if ya still thanking Doctors and NHS ya might as well thank this lot
