Short Summary

This study investigates the impact of idealized anthropogenic aerosol reductions in China on the East Asian Summer Monsoon (EASM) and weather extremes. It finds that such reductions lead to a stronger EASM, regional warming, increased precipitation, and an intensification of summertime extreme temperatures and precipitation.

Objective

• To investigate the future changes in East Asian Summer Monsoon (EASM) and weather extremes responding to idealized local emission reductions of anthropogenic aerosols (AA) in China, while greenhouse gases and other anthropogenic climate forcers are kept at present-day (2015) levels.

Study Configuration

• Spatial Scale: East Asia, eastern China, China.
• Temporal Scale: Future changes, specifically 2030 and 2060, relative to present-day (2015) levels, focusing on June-July-August (JJA) mean.

Methodology and Data

• Models used: An aerosol-climate model.
• Data sources: Time-slice simulations, localized carbon neutral emission scenario.

Main Results

• Anthropogenic aerosol (AA) reduction in China leads to a positive change in June-July-August (JJA) mean effective radiative forcing over eastern China.
• A warming of 0.2 °C to 0.4 °C is projected for 2030 and 2060, respectively, over eastern China.
• The temperature difference between land and ocean intensifies.
• Precipitation over eastern China increases.
• East Asian Summer Monsoon (EASM) intensity in JJA is estimated to be strengthened.
• Summertime extreme temperatures and precipitation in China are intensified.

Contributions

• This study reveals the important role of reductions of anthropogenic aerosol emissions in influencing the East Asian Summer Monsoon and weather extremes, providing crucial insights for emission policymaking and mitigation strategies.
