Short Summary

This study investigates the intensification of concurrent heatwaves over Europe and North China, revealing that future events will be more severe than previously projected. The research highlights the importance of considering compound risks in climate projections.

Objective

• Investigate the mechanisms driving the intensification of concurrent heatwaves over Europe and North China under future climate change scenarios.

Study Configuration

• Spatial Scale: Continental scale (Europe and North China)
• Temporal Scale: Historical period (1920–2005) and future projection period (2070–2100)

Methodology and Data

• Models used: Large‐ensemble simulations using the ECMWF model
• Data sources: Observations from satellite and surface weather stations, reanalysis datasets

Main Results

• Future concurrent heatwave events intensify substantially relative to the historical period, with excess warming exceeding 0.5°C locally and 0.3°C regionally.
• The intensification is driven by fundamentally different mechanisms in the two regions: strengthened ridges over North China promoting subsidence and clear‐sky conditions, and progressive soil drying under climate change reducing evaporative cooling over Europe.

Contributions

• This study demonstrates that concurrent heat extremes will intensify beyond the mean climate response, highlighting a compound risk not captured by mean-state projections.
• The findings provide new insights into the mechanisms driving the intensification of concurrent heatwaves, which is essential for improving climate projection and risk assessment.
