Reuters: China bets on AI weather forecasting as extreme weather intensifies. “For decades, weather prediction has relied on numerical models running ​on supercomputers that simulate atmospheric physics. AI models instead learn patterns from vast archives of ⁠historical weather observations and can produce forecasts in a fraction of the time. The technology is increasingly being tested […]

Washington State University: Wondering about tomorrow’s air quality? Check WSU’s new interactive tool. “The tool provides information on fine particulate matter and ozone concentrations, as well as fire locations and intensity, smoke layers, meteorological conditions, and other data on an hourly basis for Washington, Oregon and Idaho, along with parts of surrounding states. Enter your […]

RainViewer's GA4 data across France, Italy, Czechia, and Germany shows weather app usage spikes with uncertainty - not heat - as storms approach. https://hackernoon.com/the-real-trigger-for-weather-app-usage-isnt-heat-its-uncertainty #weatherforecasting

#ESA:
"
Building on the remarkable success of the Earth Explorer Aeolus wind mission,.. given Airbus Defence and Space in the UK the authorisation to proceed to begin the development of Aeolus’ successor, Aeolus-2 – which is set to be built to enhance operational weather forecasts.

Gizmodo: Here’s Why Weather Forecasts Have Seemed So Inaccurate Lately. “Before the cuts, the NWS was launching weather balloons twice per day (once in the morning and once in the evening) from 100 locations. Today, the number of morning launches in the Lower 48 has been reduced by half, according to MyRadar senior meteorologist Matthew Cappucci.”

China's LineShine Supercomputer: A Sense of Scale ⚡🖥️

China's LineShine 灵晟 supercomputer is the most powerful supercomputer in the world 🌍, delivering a verified 2.198 exaFLOPS on the TOP500 benchmark. That means it can perform more than 2 quintillion (2×10¹⁸) calculations every second 🚀. The system consumes 42.2 megawatts of electricity ⚡ and is powered by more than 13.7 million conventional CPU cores 🧠.

The Scale of Its Computing Power 📊

Compared to Humanity 👥: If every person on Earth performed one mathematical calculation every second, without stopping ⏱️, it would take the entire global population about 4 years 📅 to equal the amount of computation LineShine completes in a single second.

Consumer Hardware 💻: Matching LineShine's sustained performance would require more than 20 million of today's fastest consumer graphics cards 🖥️, such as an RTX 5090, working together in perfect synchronization 🔗.

LineShine demonstrates the extraordinary scale of modern high-performance computing (HPC), enabling scientific calculations that would be practically impossible using conventional computers 🚀.

My colleagues and I published the system I've been building at ECMWF.

AIFS combines graph neural networks with a sliding window transformer, trained on 40 years of ERA5 data. It produces 10-day forecasts in about 2.5 minutes on a single GPU, runs four times daily alongside the physics-based IFS, and is publicly available under ECMWF's open data policy.

This is what data-driven weather prediction looks like in production.

AI Is Changing the Way We Predict the Weather. It’s More Perilous Than We Think

On November 12, 1970, the Bhola cyclone slammed into the coast of what was then East Pakistan. The…

I work in this field and this paper captures the moment everything shifted.

This is the first side-by-side comparison of ML-generated forecasts against operational NWP, initialized from identical conditions. PanguWeather matches the IFS for global metrics and extremes, though smoothness and bias drift remain open problems.

Data-driven weather forecasting went from "interesting" to "operational" while we were writing this.
