Short Summary

This study investigates the impact of climate change on global precipitation patterns using a high-resolution climate model. The main finding is that the model simulates an increase in extreme precipitation events worldwide.

Objective

• Investigate the effect of climate change on global precipitation patterns

Study Configuration

• Spatial Scale: Global, with a focus on regions with significant changes in precipitation patterns
• Temporal Scale: Long-term (30-year) simulations to capture trends and variability

Methodology and Data

• Models used: High-resolution version of the Community Earth System Model (CESM)
• Data sources: ERA5 reanalysis data for initial and boundary conditions, as well as output from CESM simulations

Main Results

• Global mean precipitation increases by 4.2% over the 30-year simulation period
• Extreme precipitation events (defined as those exceeding the 95th percentile) increase by 15.6% globally
• Regional analysis reveals significant changes in precipitation patterns, with some areas experiencing more frequent and intense droughts while others experience increased flooding

Contributions

• This study provides new insights into the impact of climate change on global precipitation patterns at high spatial resolution
• The results highlight the importance of considering extreme events when assessing climate change impacts
