Short Summary

This study investigates the impact of anthropogenic greenhouse gas emissions on extreme precipitation in the Huaihe River basin (HRB) and explores the underlying causes using observational data and CMIP6 model experiments. The results show that greenhouse gas emissions have led to an increase in extreme precipitation events in the HRB.

Objective

• Investigate the effect of greenhouse gas emissions on extreme precipitation in the Huaihe River basin

Study Configuration

• Spatial Scale: Regional (Huaihe River basin)
• Temporal Scale: 1961–2020, with a focus on summer months

Methodology and Data

• Models used: CMIP6 models (greenhouse gas forcing experiment and natural forcing experiment)
• Data sources: Observational data from the HRB, CMIP6 model experiments

Main Results

• Summer average R95p over the HRB has increased by 26.21% in 1961–2020.
• Greenhouse gas forcing experiment found a faster increase in R95p than natural forcing experiment in selected CMIP6 models.
• Extreme precipitation years in greenhouse gas forcing experiment increase by 57.14% compared with natural forcing experiment.

Contributions

This study provides new insights into the mechanisms by which greenhouse gas emissions influence regional extreme precipitation, and highlights the importance of considering anthropogenic factors in long-term forecasting of extreme precipitation events in the HRB.
