Why Accurate Weather Forecasting Remains Difficult: The Role of Real-time Data and Atmospheric Complexity

Summary

Accurate weather forecasting remains challenging due to the atmosphere's complex, constantly changing nature and the difficulty in obtaining a complete, real-time picture from various instruments. Models struggle with rapidly evolving weather systems and small-scale events, while the "butterfly effect" highlights how initial uncertainties grow over time, leading to the use of ensemble forecasts. Latency in data collection also significantly impacts forecast accuracy.
