Short Summary

This study presents a dynamical adjustment framework to estimate the circulation-induced temperature at daily timescales and its subsequent trends over 1979–2024 in Europe. The framework uses a convolutional neural network trained on CMIP6 simulations and fine-tuned on reanalysis data.

Objective

• Investigate the role of atmospheric circulation in European temperature increase over recent decades

Study Configuration

• Spatial Scale: Continental-scale analysis for Europe
• Temporal Scale: Daily timescale with trends analyzed over 1979–2024

Methodology and Data

• Models used: Convolutional neural network (UNET) based on CMIP6 simulations
• Data sources: Reanalysis data, CMIP6 simulations

Main Results

• Temperature trends induced by circulation at 850 hPa: 0.05 (−0.03, 0.14)°C/decade annually
• Seasonal variations:
  • Summer: 0.08 (−0.00, 0.17)°C/decade
  • Winter: 0.09 (−0.11, 0.29)°C/decade

Contributions

• Provides high reconstruction scores at daily timescales for circulation-induced temperature trends
• Highlights the importance of atmospheric circulation in European temperature increase over recent decades

Funding
