Every chart, data insight and key finding in the #ESOTC2024 is the result of international teamwork. A collective effort by #C3S—implemented by #ECMWF and supported by the European Commission—alongside WMO and contributors worldwide, the report drives critical understanding of our evolving climate.

@Ellis_ramblings Seit wenigen Monaten wird KI in der #Wettervorhersage benutzt, z. B. mit dem #AIFS des #ECMWF:

Google hat auch ein AI-Wettermodell: GraphCast.

Ein neues System für kurzfristige #Wettervorhersagen und langfristige #Klimaprognosen nutzt künstliche Intelligenz, um Ergebnisse zu erzielen, die mit den besten vorhandenen Modellen vergleichbar sind, jedoch deutlich weniger #Rechenleistung benötigen. Das #NeuralGCM-Modell kombiniert traditionelle Modelle mit maschinellem Lernen und bietet erhebliche #Rechenleistungseinsparungen.
@ECMWF's Artificial Intelligence Forecasting System (AIFS) is now operational, issuing forecasts from a single model run.
https://www.ecmwf.int/en/about/media-centre/news/2025/ecmwfs-ai-forecasts-become-operational
Using the 2025-03-01 06:00 UTC AIFS Single forecast, here is the 2025-03-01 18:00 UTC (T+12h) forecast mean sea level pressure and 6-hour accumulated #precipitation (water equivalent) over Europe and North America.
European Weather Service: New AI weather model needs 1000 times less electricity.
The European Center for Medium-Range Weather Forecasts (ECMWF) is making available data from a new AI-based weather model that is significantly more accurate and requires around 1000 times less energy to produce a forecast.
(Please also see Phil Browne's comment below for ECMWF's open data plans)
There are a quite a lot of weather companies and even national weather services around the world that depend on the freely and reliably available global model data from the US NWS.
There is now a real risk that this access will be shut off or made unaffordable.
I really do hope that @ECMWF is thinking about this and considering to finally make their model data freely available for at least non-member state weather services - in particular in the global south.
IMO the model data in full should be free for everyone (like the US data has been for decades) since it is tax payer funded and would allow weather companies around the world to run their own models and innovate products and services.
I've always found it ironic that the US is so much more generous with their data than the "socialist" Europeans are.
People of #Ireland, beware. Weather models are really bullish on the #windstorm that's arriving from the Atlantic on friday. These are insane gust speeds, and the #storm is quickly followed by a second one. That one is not as strong, but can worsen the damage of the first substantially. Pay attention!
maps generated by @Meteologix . Great service!
Falls jemand noch genauere Erklärungen zur Transformation #Deutschlands in ein #Anbaugebiet von Zitrusfrüchten erfahren möchte, dann gibt es hier die Aufzeichnung der #Pressekonferenz #Copernicus #ECMWF:
2024 war das bisher wärmste Jahr weltweit: Zum ersten Mal lag die durchschnittliche globale #Temperatur über 1,5°C über dem vorindustriellen Niveau.

Menschgemachter #Klimawandel bleibt der Haupttreiber extremer Temperaturen an Land und im Meer. Auch das #Wetterphänomen #ElNiño trug dazu bei. Daten von Organisationen wie #ECMWF, #NASA und #WMO unterstreichen die außergewöhnlichen Bedingungen des vergangenen Jahres. 
Rapid Surge In Global Warming Mainly Due To Reduced Planetary Albedo

"Apokalypse für diese Woche geplant. "
Liest man auch nicht so oft.
@JZ_Lpz
Interessant!
Ich wollte das Maximum des derzeit physikalisch Möglichen an Starkregen in Europa herausfinden. Dafür hab ich beim TIGGE Archiv vom ECMWF die 50 Ensemblemember mit all ihren "pertubed" Forecasts runtergeladen und laufende 3Tagessummen aufsummiert.
Man kann bei TIGGE auch andere Modelle runterladen, aber ich nahm #ECMWF, weil ich halt nicht besser wusste. Außerdem noch vom original 0.5x0.5 grid auf 1x1 interpoliert, um Plattenplatz u Zeit zu sparen. Auch ne schlechte Idee gewesen, da die Maximalwerte dabei verloren gegen.
Das Ergebnis war extrem ... unbeindruckend. Das Maximum aller 3-Tagessummen seit 2020 lag in der Nordost -Türkei, im Oktober 2024.
Der 1x1 Gridpunkt Valencia waren (aus dem Kopf) bloß 300mm oder so.
Um das heute physikalisch Mögliche bei Starkregen mal annähernd abzubilden, sollte ich also pertubed #GFS-Member in Originalauflösung seit 2020 runterladen und 3Tagessummen bilden?
Ah jee... das dauert wirklich ewig. Einmal das Bereitstellen durch #TIGGE, und dann vor allem auch das Processing auf meinem Läppi...
Kannst Du das nicht mal für uns tun und dann als Clickable Europakarte auf Eure Webseite stellen?
GARR, Switch, GÉANT teamed up to interconnect the Swiss National Supercomputing Centre (CSCS) in Lugano
and the European Centre for Medium-Range Weather Forecasts (@ECMWF) in Bologna
with a state-of-the-art, ultra-large bandwidth dedicated connection.
This opens new perspectives for #research in #meteorology and scientific #computing, and aims to accelerate progress in climate modelling & weather forecasting.

"9 of the first 10 months this year, and 15 of the last 16 months exceeded 1.5°C global average surface air temperature compared to pre-industrial levels."

Look. These high September temperatures in Greifswald and Potsdam had already been physically possible 110 to 130 years ago, when #GlobalWarming was at ±0°C.
It merely only happened once.
And today.
But we haven't experienced yet what the physically possible is in today's CO2-charged weather.
Knowing this would be very valuable regarding #climate adaptation.
Do you know where we can get such information on today's physically possible?
By exporting the maxima from each Forecast Ensemble Member since 2020. 
A clickable map in a 1°by1° land-only grid, showing the maxima for °C, rain and stuff like 6-hour sustained °C and relative humidity, or 48hr rain and so on.
I asked the boss of #ECMWF Forecast
but they don't want to produce such a clickable map. What they did give me:
a URL to past Ensemble Member data so I can do it myself ! #OpenData https://confluence.ecmwf.int/display/TIGGE/TIGGE+archive
Had a quick look at #Tigge but it's too hot for my poor brain to make sense of it. Maybe this winter. Or you?
#ECMWF needs your input to enhance their open-data offerings. Earlier this year, they released the IFS and AI-based AIFS models at a 0.25° resolution. Now, they want to hear from you on how their data is being used to help shape the direction of their future offerings. You can take part of the survey here: https://ec.europa.eu/eusurvey/runner/ECMWF-open-data-2024
