# AFDBench: Area Forecast Discussion Benchmark

AFDBench evaluates how well AI models generate professional meteorological text compared to Human NWS Forecasters.

### Core Metrics:
1. **Met-Align**: Physical accuracy vs. Human numerical choices.
2. **Style-Align**: Linguistic alignment with NWS AFD professional prose.

Initial results on 7,734 human samples reveal a massive **Meteorological Hallucination Gap** in zero-shot open models.
