Short Summary

This study investigates the temporal evolution of heatwaves in East Asia using observations and CMIP6 simulations, finding that heatwaves intensify faster than they dissipate and that future changes depend on how extremes are defined.

Objective

• Investigate the lifecycle dynamics of heatwaves across East Asia, focusing on onset and decay rates.

Study Configuration

• Spatial Scale: Regional (East Asia)
• Temporal Scale: 1979–2024 (observations) and CMIP6 simulations

Methodology and Data

• Models used: CMIP6 simulations (e.g., ISBA, mHM)
• Data sources: Observations from East Asian weather stations and satellite data

Main Results

• Heatwaves consistently intensify faster than they dissipate across East Asia.
• Stronger asymmetry in heatwave lifecycle dynamics is observed at higher latitudes.
• Future changes depend strongly on how extremes are defined.

Contributions

• This study provides new insights into the temporal evolution of heatwaves in East Asia, highlighting the importance of considering climate reference frameworks when interpreting projected changes.
• The results demonstrate that heatwave lifecycle characteristics may change under continued warming, involving changes in climate variability and atmospheric circulation processes.
