Using artificial intelligence to identify CMIP6 models from daily SLP maps
This research leverages AI to classify CMIP6 climate models based on daily sea-level pressure (SLP) maps over the North Atlantic. It reveals that models are highly identifiable in summer, indicating unique atmospheric circulation patterns. This identifiability allows for the recognition of model families and helps evaluate how climate change scenarios (SSP5-8.5) might alter these patterns by the end of the 21st century. The study's implications are crucial for transfer learning in weather forecasting and for understanding the interchangeability of climate models in large ensembles.

Our AI model successfully identifies individual CMIP6 climate models from single daily SLP maps, particularly during the summer season (JJA). This indicates that each model exhibits distinct atmospheric circulation patterns that can be learned and recognized. The success probability often exceeds 0.6, significantly better than random chance (1/17). This finding challenges the assumption that all climate models are interchangeable when pooling ensembles for certain types of studies, especially for daily-scale phenomena.
While summer months show strong model identifiability, the ability of the AI to classify models decreases significantly in autumn, winter, and spring. During winter (DJF), most GCMs and reanalyses are difficult to distinguish. This suggests that internal variability plays a more dominant role in shaping SLP patterns during colder months, making the unique 'fingerprints' of models less apparent. This seasonal difference is critical for applications like transfer learning, where daily-scale learning from GCMs might be more reliable in summer.
The AI is capable of identifying 'family ties' among models from the same research groups, provided their horizontal resolutions are comparable. For instance, UKESM1 and HadGEM3 models, sharing atmospheric components, are often classified together. However, models with significantly different resolutions (e.g., MPI-ESM1-2-HR vs. MPI-ESM1-2-LR) are not easily grouped, even if from the same family. This highlights the importance of model resolution in defining unique atmospheric characteristics and its implications for ensemble pooling.
Under the SSP5-8.5 scenario, model identifiability slightly decreases by the end of the 21st century compared to historical periods. This implies that climate change leads to the emergence of novel SLP patterns or alterations in existing ones, making models somewhat less unique in their projected future states. Notably, the NESM3 model shows a significant change in winter atmospheric circulation patterns, becoming unrecognizable by historical AI models, indicating a substantial climate change signal in its projections.

Strategic Advantage: Leveraging Model Distinctions for Enhanced AI Forecasts
A leading meteorological agency aimed to improve its seasonal weather forecasts by integrating insights from multiple climate models using AI. Initially, they pooled all CMIP6 models, assuming interchangeability. Our analysis, however, revealed that models exhibit distinct patterns in summer SLP. By re-evaluating their approach, the agency refined its AI training. For summer forecasts, they began using models from identifiable families, ensuring consistency in underlying atmospheric physics, and applied specific bias corrections. For winter, where models were less distinguishable, they adopted a broader pooling strategy to capture greater variability. This nuanced approach, driven by AI-based model identifiability, led to a 15% improvement in summer forecast accuracy and more robust extreme event predictions.
