Google DeepMind and Google Research’s AI weather model WeatherNext predicted hurricane tracks and intensity more accurately than existing forecasting models, researchers said. The team said it typically provides about one extra day of usable lead time, with three-day forecasts matching the accuracy of other models’ two-day outlooks. A Nature paper detailed the results, including a 2025 Hurricane Melissa case in the Caribbean. Experts said AI supports, but does not replace, forecasters.

Cho Yong-min (조용민), CEO of venture investment firm Unboundlabdev, said South Korea should concentrate AI investment on infrastructure bottlenecks to expand its stake in the global AI market, rather than competing with big tech on general-purpose model performance. He identified four key bottlenecks: memory, interconnect, thermal management and power. Cho said competitiveness comes from deep integration into customers’ work, and urged government policy to target value chains where Korea is strong and future bottlenecks.
