Abstract

The article discusses recent findings that challenge the established two-week limit on weather forecasting, traditionally rooted in chaos theory and the "butterfly effect." Researchers at the University of Washington, using Google's AI model GraphCast, have demonstrated the potential for accurate weather predictions extending beyond 30 days, although these forecasts have only been tested with historical data rather than real-time conditions. While the results are promising, experts caution that the model's adjustments to initial conditions may not reflect true atmospheric states, raising questions about the reliability of such long-range forecasts. The ongoing research suggests that the limitations of weather prediction may be more complex than previously understood. [Extracted from the article]
