The openingWhy this idea is overlooked

For decades, running sophisticated weather models required supercomputers, so everyone assumed serious forecasting was closed to newcomers. AI changed the math: the report cites roughly a 1000-fold reduction in computational energy per forecast for an operational AI system (a context figure), which fundamentally lowers the capital barrier to running advanced models at all. It is overlooked because the mental model of weather as a supercomputer-only field has not caught up to the cost collapse, leaving room for lean, focused entrants who exploit the new economics before incumbents' cost advantage reasserts.
