Short Summary

This study investigates the impact of atmospheric rivers (ARs) on humid heatwaves (HHWs) across mainland China and finds that ARs increase HHW intensity by 13.0% with pronounced intensifications in Northwest and Northeast China.

Objective

• Investigate the role of atmospheric rivers in modulating humid heatwaves in East Asia, specifically in mainland China

Study Configuration

• Spatial Scale: Mainland China (including provinces of Northwest and Northeast China)
• Temporal Scale: Summertime (June to August)

Methodology and Data

• Models used: Not specified
• Data sources: Satellite data, observation data, reanalysis data

Main Results

• ARs increase the average HHW intensity in mainland China by 13.0%
• Pronounced intensifications of 19.6% in Northwest China and 19.3% in Northeast China
• Relative amplifications of extreme HHWs in Northwest China (93.9%) and Northeast China (237.9%)

Contributions

• Provides new insights into the role of atmospheric rivers in modulating humid heatwaves in East Asia, highlighting their importance for forecasting and early warning systems
