Short Summary

This study investigates the mechanisms driving interdecadal shifts in Eurasian precipitation patterns under global warming. The results show that a synergized oceanic forcing mode linking the Indo-Pacific Warm Pool (IP), the southwestern Pacific, and the North Atlantic was established around 1986, which modulated the interdecadal increase in precipitation across the Eurasian continent via atmospheric teleconnections and moisture transport processes.

Objective

• Investigate the driving mechanisms of interdecadal precipitation variability over the Eurasian continent under global warming.
• Examine the linkages among different regions and whether there exists a synergistic driving mechanism involving multiple ocean basins.

Study Configuration

• Spatial Scale: Global to regional (Eurasia)
• Temporal Scale: Interdecadal (1941-2020)

Methodology and Data

• Models used: Community Atmosphere Model version 5 (CAM5)
• Data sources: Satellite, observation, reanalysis datasets

Main Results

• A synergized oceanic forcing mode linking the IP, southwestern Pacific, and North Atlantic was established around 1986.
• This mode modulated the interdecadal increase in precipitation across the Eurasian continent via atmospheric teleconnections and moisture transport processes.
• The study highlights the critical role of multi-basin synergy in driving interdecadal shifts in Eurasian precipitation patterns.

Contributions

• Provides a systematic understanding of the mechanisms driving interdecadal shifts in Eurasian precipitation patterns under global warming.
• Highlights the importance of considering multiple ocean basins in understanding regional climate responses to global change.

Funding

• This study was supported by the National Natural Science Foundation of China (Grant No. 41690144) and the Chinese Academy of Meteorological Sciences (Grant No. CMA2019KJ001).
