Short Summary

This study investigates the relationship between daily precipitation intensity and frequency in China. The results show a positive correlation between these two variables, indicating that an increase in precipitation intensity is associated with an increase in precipitation frequency.

Objective

• Investigate the drivers of the positive correlation between daily precipitation intensity and frequency in China

Study Configuration

• Spatial Scale: Continental scale (China)
• Temporal Scale: 1960-2021 (61 years)

Methodology and Data

• Models used: ERA5 reanalysis dataset
• Data sources: Gauge observations, satellite data, and reanalysis datasets

Main Results

• A positive correlation between daily precipitation intensity and frequency is observed across China.
• The correlation is stronger in the eastern part of China compared to the western part.

Contributions

• This study provides new insights into the relationship between precipitation intensity and frequency at a continental scale.
• The results have implications for understanding the impact of climate change on precipitation patterns in China.

Funding

• National Natural Science Foundation of China (NSFC)
• Chinese Academy of Meteorological Sciences (CAMS)
