Short Summary

This study quantifies moisture source contributions to extreme, moderate, and light precipitation events over the Tibetan Plateau from 1979 to 2020, revealing that extreme and moderate events are primarily driven by the Indian monsoon, while light events are dominated by westerlies, with external moisture sources contributing significantly across all types.

Objective

• To quantify moisture source contributions to three types of precipitation events—extreme precipitation (EP), moderate precipitation (MP), and light precipitation (LP)—over the Tibetan Plateau.

Study Configuration

• Spatial Scale: Tibetan Plateau
• Temporal Scale: 1979 to 2020 (42 years)

Methodology and Data

• Models used: Lagrangian-based HYSPLIT model
• Data sources: Specific data sources (e.g., satellite, observation, reanalysis) are not detailed in the provided text.

Main Results

• Extreme precipitation (EP) and moderate precipitation (MP) events are primarily influenced by the Indian monsoon, with the Bay of Bengal and Arabian Sea identified as key sources.
• Light precipitation (LP) events are dominated by westerlies.
• The western pathway contributes 15.55% to EP, 36.28% to MP, and 59.59% to LP events.
• The monsoon pathway accounts for 40.56% of moisture for EP, 28.23% for MP, and 31.21% for LP events.
• External moisture sources dominate across all event types, contributing an average of 87.7% of the moisture.
• Local recycling contributions decrease from LP events (12.90%) to EP events (11.55%).

Contributions

• Enhances the understanding of moisture–precipitation coupling mechanisms over the Tibetan Plateau, particularly by differentiating contributions based on precipitation intensity.
• Provides a scientific basis for water resource management strategies under changing climate conditions in the region.
