Extreme Weather Events
Every hour of lead-time on a hurricane or supercell is a life saved — and a race against the solver's clock.

Where Physics Still Beats Pattern Recognition
Extreme weather forecasting is the sharpest edge of meteorology: hurricanes, supercells, and record-breaking heat or cold events. Recent research shows that AI weather models, while fast and accurate for average conditions, systematically underestimate the intensity and frequency of unprecedented extremes because they are trained on historical data that, by definition, contains no record of events beyond the record. Malgukke architectures are built to run physics-based ensemble models and AI systems side by side, giving forecasters both speed and the physical fidelity that extremes demand.

Running on the TOP500: Dogwood & Cactus
Dogwood (Manassas, VA) & Cactus (Phoenix, AZ) — NOAA
NOAA's twin operational supercomputers, each delivering 12.1 petaflops, were ranked No. 49 and No. 50 on the TOP500 list at their 2022 deployment and remain NOAA's primary machines for the National Weather Service today. They were built specifically to run the Hurricane Analysis and Forecast System (HAFS), the Global Forecast System (GFS), and severe-storm models — the exact extreme-weather workloads described on this page.
Yes — these are real, currently operating TOP500-ranked systems (as of their most recent published ranking), purpose-built for hurricane and severe-storm forecasting rather than for climate research generally.
