Zephyrus-R1: Agentic Reinforcement Learning for Weather Reporting

Key points

• To address this, we develop Zephyrus-R1, a practical framework for RL on scientific weather forecast reporting.1
• We focus on three key components of the agentic RL pipeline: reward design, curriculum learning, and an analysis of human-expert alignment.1
• To encourage both report legibility and factual accuracy, we design a reward function that combines a meteorological rubric with bidirectional claim entailment, both evaluated against National Weather Service reference reports.1
• Our framework optimizes this reward in a simulated tool-calling environment, enabling vision-language agents to gather and analyze forecast evidence across regions and lead times before producing a report.1

  Reinforcement learning (RL) has emerged as a key method for training AI models in scientific applications, but RL remains difficult when outputs cannot easily be verified against a known ground-truth answer.

  To address this, we develop Zephyrus-R1, a practical framework for RL on scientific weather forecast reporting.
