Pixels and Predictions: Potential of GPT-4V in Meteorological Imagery Analysis and Forecast Communication

GPT-4V shows promise for weather forecasting tasks: The AI successfully generated a severe-weather outlook from meteorological charts that "corresponds well with a Storm Prediction Center human-issued forecast," suggesting potential to augment existing forecasting methods.

AI hallucinations remain a critical concern: The paper identifies "hallucinations" as a key challenge—instances where GPT-4V produces "coherent, confident, but incorrect responses"—highlighting why human oversight is essential before deploying such tools in high-stakes weather communication.

Language translation capabilities are limited: While GPT-4V can produce hazard summaries in multiple languages, Spanish translations were found to be direct, non-idiomatic translations that "lose critical idiomatic precision required for optimal communication," meaning the AI cannot yet reliably serve diverse language communities without human review.

Human oversight is non-negotiable: The authors explicitly advocate for "cautious integration" of AI tools in meteorology and emphasize "the necessity of human oversight," indicating that AI should complement rather than replace meteorologists' expertise.

Explainability matters for public safety: The paper calls for development of "trustworthy, explainable AI," suggesting that for weather communication—which directly affects public safety decisions—users need to understand how and why the AI reached its conclusions.
