Short Summary

This study investigates the long-term variations and driving mechanisms of precipitation water conversion rate (PWCR) in the Yangtze-Huanghe-Huaihe-Haihe River (YHHH) basin, China, from 1956 to 2024. The results show a significant decline in PWCR under a warming and drying background.

Objective

• Investigate long-term variations of precipitation water conversion rate (PWCR) in the Yangtze-Huanghe-Huaihe-Haihe River (YHHH) basin, China

Study Configuration

• Spatial Scale: Large monsoon-influenced basin (Yangtze-Huanghe-Huaihe-Haihe River)
• Temporal Scale: 1956 to 2024 (68 years)

Methodology and Data

• Models used: Not specified in the paper
• Data sources: Observational data, reanalysis

Main Results

• PWCR decreased significantly at a rate of −1.19%·dec−1
• IWV increased by 2.83 mm·dec−1
• Precipitation decreased by −18.95 mm·dec−1

Contributions

• This study provides new insights into the long-term variations and driving mechanisms of PWCR in large monsoon-influenced basins, improving understanding of water vapor–precipitation transformation.

Funding

• Not specified in the paper
