Heard about all them new-fangled AI NWP systems like "GraphCast", "PanguWeather", and "FourCastNet" and want to try them out yourself? Let me help you with that -> github.com/darothen/ai-mo… This is just a quick preview release; see README for details. Feedback very welcome!

@ClimateHome This is heartbreaking. One decent man who tried to reach across the divide has been killed. The tragedy is the same thing has happened to 1000s of others, and it's almost impossible to fathom. May his decency and deeds have the effect he would have wanted, eventually.

@clcoding Or a long version: import numpy as np n = int(input('Enter number of rows\n')) idx = np.abs(np.arange(-n + 1, n)) X, Y = np.meshgrid(idx, idx) print(*np.where(X + Y < n, '*', ' ').view(f'<U{n * 2 - 1}').flat, sep='\n')

"Escape From Model Land" is coming out in #paperback next week - if you've been waiting and haven't ordered it yet, now's a good time! Also in #hardback, #Kindle and #audiobook for every kind of reader... Lovely cover too, ideal Christmas gift for that hard-to-buy-for relative!

Graphcast has hit press in Science today: science.org/doi/10.1126/sc…, and the blog claims "GraphCast is now the most accurate 10-day global weather forecasting system in the world". Bold claim for a model that initializes from ERA-5

@DopplerChase Interesting and useful to see this. Wonder if there will be any artefacts around the end of 2023 in future papers using IMERG data?

Curious why GPM data products have stopped flowing? This is because on Nov 7-8 the spacecraft was 'boosted' to a higher orbit to hopefully extend GPM's lifetime till the 2030s. Data should start flowing again next year. Read more about it here: gpm.nasa.gov/missions/gpm/o…

As the police in central London work to contain the far-right, and everyone starts to blame Suella Braverman, just remember who chose to not only give her the job but also chose not to sack her. Rishi Sunak is as, if not more, responsible for what happens today.
