Original Summary

I started this four and a half years ago. I wanted to build a climate model as both a toy and educational tool that I could visualize in a web browser. I have always been interested in meteorology and asked r&#x2F;ClimateScience for advice on the math and physics on building an in-browser climate model as an educational tool, and a few people said it was far too ambitious. They were right. I could build the geometry, an icosahedral hexagonal grid on a globe, and I have an intuitive understanding of the math but integrating the Navier-Stokes equations and the physics proved to be too difficult for me, and the closest I got after nearly of month of work was a model that blew up within two simulated days.<p>Fast forward 4 and a half years. I figured that if models like Claude and GPT Astra could solve a milennium prize problem about fluid dynamics then they could help me fix the broken model and iterate on it until my vision was realized. On Friday, I threw down $200 for a Claude Max subscription, and this is the result of a single weekend&#x27;s work on top of where I had left off.<p>What it is now, in technical terms: a hydrostatic primitive-equation atmosphere on that hex grid (the TRiSK scheme MPAS uses), 27 levels, about 41,000 cells at 110 km, with grey radiation, moist convection, a boundary layer, sea ice, a land surface with snow, a two-layer ocean and real topography. Every kernel runs on the GPU; on my MacBook Pro (M1 Max) it does about 70 simulated hours a minute from a six-year spin-up, hence the 50 MB first load. You can color the globe by twenty-odd fields, animate wind or currents, draw isobars, or view it from space under the model&#x27;s own sun. The URL captures the view, so links open specific places.<p>Caveats: an educational model, not a validated one. It runs about four degrees colder than Earth and I&#x27;m still tuning it, the ocean is crude and shallow, and it needs WebGPU (Chrome, Edge, Safari 26) for best performance. It&#x27;s currently tuned for my specific machine specs but I suspect it will run well on most desktop-class Apple Silicon machines from the past 5 years.<p>Source and design notes: <a href="https:&#x2F;&#x2F;github.com&#x2F;jlhawn&#x2F;geodesic" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;jlhawn&#x2F;geodesic</a>
