This is an unreviewed algorithmic system combining machine learning and language models to generate weather alerts for plateau tourism. The authors report improvement in an internal composite quality metric (from 4.2 to 8.9) across 12 optimization iterations, but provide no independent validation, comparison to existing warning systems, or evidence of real-world utility or safety.
Single-arm algorithmic system development and iterative optimization study. Tourism meteorological services on plateau terrain; system trained and evaluated on high-wind, precipitation, and low-temperature weather events. No statement of geographic region, time period, or dataset origin.. Intervention: SmartWeatherAgent system: unified three-stage ML-LLM architecture with rule-based parsing, LightGBM hazard prediction, and prompt self-optimization for structured weather alert generation.. Not stated.
LightGBM model with highland-specific features achieved F1-Macro score of 0.605 on high-wind, precipitation, and low-temperature events Prompt self-optimization loop increased composite warning quality score S_final from 4.2 (B01) to 8.9 (B12), representing a 112% increase Data source citation score rose from 6.5 to 8.5 (B08); scientific rigor score peaked at 9.2 (B12)
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Not applicable. This is a meteorological informatics system, not a clinical intervention. Practitioners should recognize that reported improvements are internal metrics without external validation or comparison to current alert standards.
Single-center algorithmic development study with surrogate endpoints (F1-score, quality metrics) in a novel application domain; no clinical outcome, no peer review, and no comparison to standard meteorological warning practices reported.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
To address insufficient contextualization, weak generalization, and poor scenario adaptation in tourism meteorological services, we propose SmartWeatherAgent--a unified three-stage architecture integrating intent recognition, hazard prediction, and reasoning-enhanced generation. The system fuses rule-based methods with large language models to parse queries at multiple granularities and employs a LightGBM model enriched with highland-specific features (e.g., wind speed abruptness rate), achieving an F1-Macro score of 0.605 with 1.60 ms latency on high-wind, precipitation, and low-temperature events. A 12-round micro-step prompt self-optimization loop boosts the composite warning quality score S_final from 4.2 (B01) to 8.9 (B12, +112%). Key improvements include a sharp rise in B08 from data source citation (6.5 -> 8.5), sustained high performance in B10 via physical mechanism explanation, and a peak scientific rigor score of 9.2 in B12 through explicit uncertainty statements. The system autonomously generates structured warnings that integrate causal mechanisms, spatiotemporal evolution, quantitative evidence, regulatory references, and confidence statements--enhancing professional depth, logical rigor, and scientific soundness, and advancing meteorological services toward proactive perception, explainable decision-making, and intelligent agency.
