Unlocking Model Identification with AI
This study examines whether Artificial Intelligence can identify climate models from daily Sea-Level Pressure (SLP) maps over the North Atlantic. It finds models are highly identifiable in summer, allowing for the classification of climate model families and investigation into climate change impacts on SLP patterns.

Executive Impact
The ability to distinguish between climate models using AI has significant implications for climate forecasting and impact studies. This research demonstrates a clear methodology to assess model uniqueness, especially in identifying atmospheric patterns during summer, which can guide the selection of models for AI-based forecasts and attribution studies, preventing misleading data pooling.

Core Finding: Model Identifiability
The study found that climate models are highly identifiable from single daily Sea-Level Pressure (SLP) maps, particularly during the summer season. This suggests that even when statistical properties like sample means and standard deviations are similar, the underlying spatial patterns hold unique identifiers that AI can detect.
This identifiability implies that simply pooling data from different General Circulation Models (GCMs) to enlarge sample size for AI-based forecasts might be misleading, as the AI trained on one model's data may not be directly transferable to others.

Climate Change & SLP Pattern Shifts (SSP5-8.5)
Problem: Investigating how future climate scenarios (SSP5-8.5) might alter the daily SLP patterns of GCMs, potentially affecting their identifiability by an AI trained on historical data.
Solution: The study applied the AI classifier, trained on historical (1970-2000) SLP data, to SSP5-8.5 simulations from 2070-2100. This allowed for detection of shifts in atmospheric circulation patterns.
Impact: Generally, model identifiability slightly decreased in the future scenario, suggesting the emergence of new SLP patterns or shifts in existing ones. A notable exception was the NESM3 model in winter, which became unrecognizable, indicating a significant change in its atmospheric circulation patterns under SSP5-8.5.
