Uncertain dynamic response of mid-latitude winter precipitation

Understanding changes in precipitation is crucial for society and ecosystems. Studies have documented the respective contributions of anthropogenic forcing and internal variability to precipitation trends, yet discrepancies persist between observed and simulated patterns.

This study separates the thermodynamic and dynamic components of winter precipitation trends in mid-latitudes, showing that while thermodynamic contributions are well captured by climate models, the dynamic response remains uncertain and may dominate regional trends.
