Log in to snowHeads to make it MUCH better! Registration's totally free, of course, and makes snowHeads easier to use and to understand, gives better searching, filtering etc. as well as access to 'members only' forums, discounts and deals that U don't even know exist as a 'guest' user. (btw. 50,000+ snowHeads already know all this, making snowHeads the biggest, most active community of snow-heads in the UK, so you'll be in good company)..... When you register, you get our free weekly(-ish) snow report by email. It's rather good and not made up by tourist offices (or people that love the tourist office and want to marry it either)... We don't share your email address with anyone and we never send out any of those cheesy 'message from our partners' emails either. Anyway, snowHeads really is MUCH better when you're logged in - not least because you get to post your own messages complaining about things that annoy you like perhaps this banner which, incidentally, disappears when you log in :-)

AI Weather Forecasts -- No Humans Allowed...
 Poster: A snowHead
Poster: A snowHead

Google GenCast (AI) is now outforecasting physics-based, sensor-based, human-led weather models in the medium 1-to-15-day forecast window.

Google GenCast is beating the benchmark European Centre for Medium-Range Weather Forecasts (ECMWF) for 97-99% of the time.

Rival AI weather models currently include Huawei Pangu / Zhiji, and Nvidia FourCastNet.

A revolution is taking place.

This is the beginning of the end of the human snowfall forecaster.

Recommend any AI-generated snowfall forecasts for the Northern or Southern Hemisphere in 2024 and beyond are posted on this thread.

Where can we access those models?

 Well, the person's real but it's just a made up name, see?

@Whitegold, nice photo of your mountain lair!! Cool

Do you have a leather armchair and a white cat as you plot AI weather domination?? Laughing

But seriously...any links where we can see these forecasts...or are they all behind paywalls??

@luigi, The model is open source https://github.com/google-deepmind/graphcast

If you know python/Jupyter and understand the ML basics you can play with a mini model here https://colab.research.google.com/github/deepmind/graphcast/blob/master/gencast_mini_demo.ipynb

You can also try a full blown setup, but you will need to pay for GCP compute https://colab.research.google.com/github/deepmind/graphcast/blob/master/gencast_demo_cloud_vm.ipynb

This is meant for developers/forecasters to integrate with traditional computational models, not for lay consumers.

@Oleski, thanks!

Clever stuff, but beyond me, I'm afraid! Shocked

I guess laymen like myself will just see the improvements in the accuracy of forecasting filter through.

Is it a bit like a Chess computer being able to see all the games and moves that have ever been played in the past and working out which ones will be most likely to produce a winning result?

@luigi, yeah, except of course they cracked chess 2 decades ago and it wasn't even that hard. Modern DeepML/GenAI is several orders of magnitude away from that.

Hope they're getting good at predicting wildfire smoke too. They'll need something to do when the snow is gone.

Google's press release said they will be putting forecasts up in the near future. For now its nerds only.
