Short Summary

This study investigates the relationship between atmospheric rivers (ARs) and humid heat (HH) in eastern China, finding that above half of HH days coincide with ARs during boreal summer. The research highlights the broader impact area and greater severity of HH related to ARs.

Objective

• Investigate the linkage between ARs and HH events over eastern China

Study Configuration

• Spatial Scale: Eastern China region (approximate coordinates: 20°N - 45°N, 100°E - 135°E)
• Temporal Scale: 1979-2018 period

Methodology and Data

• Models used: Not specified in the paper
• Data sources: Observational data from various stations in eastern China

Main Results

• 834 humid heat days (HHDs) detected in eastern China during 1979-2018
• Above half of HHDs coincide with ARs during boreal summer
• HH related to ARs exhibit broader impact area and greater severity compared to non-AR associated HH
• Two types of HH mechanisms identified: WNPSH-affected and LPS-affected

Contributions

• This study provides new insights into the relationship between ARs and HH events over eastern China, highlighting the importance of considering AR presence when monitoring and predicting HH events.
