ZEPHYRUS: AN AGENTIC FRAMEWORK FOR WEATHER SCIENCE
ZEPHYRUS presents the first agentic framework for weather science, bridging the gap between high-dimensional numerical weather foundation models and language-based reasoning capabilities of LLMs. It features ZEPHYRUSWORLD, a Python code-based environment with tools for WeatherBench 2 data indexing, geolocating, forecasting, climate simulation, and climatology querying. The framework includes ZEPHYRUS agents (DIRECT and REFLECTIVE) that iteratively analyze data and refine approaches via conversational feedback. A new benchmark, ZEPHYRUSBENCH, comprising 2230 diverse question-answer pairs, demonstrates ZEPHYRUS's strong performance, outperforming text-only baselines by up to 44 percentage points in correctness. While excelling at many tasks, it highlights challenges in complex areas like forecast report generation, suggesting avenues for future development in long-term, large-scale weather reasoning.

While ZEPHYRUS excels at many tasks, complex challenges like long-term forecast report generation and advanced counterfactual reasoning still prove difficult for even frontier LLMs. The highest discussion score for generating textual weather reports reached only 0.27, indicating significant room for improvement in nuanced textual generation and deep meteorological reasoning from data.

Case Study: Iterative Refinement Advantage
ZEPHYRUS-REFLECTIVE vs. ZEPHYRUS-DIRECT
ZEPHYRUS-REFLECTIVE, with its multi-turn execute-observe-solution framework, outperforms ZEPHYRUS-DIRECT on OpenAI models by 0.8-2.7% correctness. This iterative approach allows the agent to assess scientific plausibility of outputs, identify anomalies, and refine code, proving more effective for nuanced textual generation tasks where direct programming results are insufficient.
