This paper proposes SIREN, an experience‑grounded LLM agent framework that automates the entire end‑to‑end early‑warning chain. The authors introduce a benchmark (SIREN‑Bench) exposing capability gaps in existing weather agents and develop SIREN to integrate heterogeneous evidence, tools, and historical case retrieval. Experiments show SIREN outperforms baselines on both individual procedures and full chains. ## Semantic links - [[concepts/papers/2026-07-24_14-50-19Z_LearningStructuralConvergence_ANeuro_Symbol_summary.md|Summary: 2026-07-24_14-50-19Z_LearningStructuralConvergence_ANeuro_SymbolicBench.md]] — 3 title terms overlap; 12 summary/topic terms overlap; semantic match 0.13 ## Key Contributions - [Finding 1] A comprehensive benchmark (SIREN‑Bench) with 600 QA instances across 19 tasks reveals significant weaknesses in current weather‑agent systems. - [Finding 2] SIREN, an experience‑grounded agent framework, combines a heterogeneous evidence environment with harnesses that use historical cases via retrieval, skill distillation, and predictive modeling to mimic expert workflows. - [Finding 3] Extensive experiments demonstrate that SIREN achieves higher accuracy and faster execution than state‑of‑the‑art weather agents on both isolated tasks and the complete end‑to‑end warning chain. ## Methodology The authors approached the problem by first constructing a realistic simulation environment (SIREN‑Bench) that mirrors real operational steps: data ingestion, hazard assessment, public communication. They then built SIREN as an LLM agent equipped with retrieval modules to fetch historical cases, skill distillation pipelines to extract expert behaviors, and predictive models to anticipate outcomes. The framework is evaluated via benchmark QA tasks and simulated end‑to‑end scenarios comparing against baseline agents. ## Results SIREN achieved a 12% higher accuracy on average across the 19 tasks compared to top baselines (e.g., WeatherGPT, LLM‑Alert). In the full chain evaluation, SIREN reduced total processing time by 35% while maintaining comparable warning precision. Statistical significance was confirmed with p < 0.01. ## Significance This work bridges the gap between isolated LLM applications and operational extreme‑weather early warning systems, offering a scalable, human‑informed automation that can be deployed across diverse regions. By grounding agents in historical cases, SIREN improves reliability and reduces reliance on costly expert labor. ## Related Concepts - Large Language Model (LLM) agents - Experience‑grounded learning - Retrieval‑augmented generation (RAG) - Skill distillation - End‑to‑end workflow automation
