Short Summary

This study investigates the characteristics and mechanisms of tropical cyclone-induced remote precipitation (TRP) events in Eastern China during summer from 1991 to 2020, revealing that TC activity drives TRP formation through large-scale circulation modifications.

Objective

• Investigate the relationship between tropical cyclones and remote precipitation events over Eastern China

Study Configuration

• Spatial Scale: Regional scale, focusing on Eastern China (approx. 30°N - 45°N, 100°E - 125°E)
• Temporal Scale: Summer season (June to August) from 1991 to 2020

Methodology and Data

• Models used: Reanalysis datasets (e.g., ERA5, JRA55)
• Data sources: Satellite observations (e.g., TRMM), reanalysis products (e.g., NCEP/NCAR)

Main Results

• Eastern China is the primary region for TRP occurrence, with precipitation patterns exhibiting a southwest to northeast oriented distribution.
• TCs influence TRP formation through intrinsic circulation and anomalous quasistationary Rossby waves, modifying East Asian circulation patterns.
• Moisture transport from the ocean to the precipitation region is more notable in the middle–lower troposphere.

Contributions

• This study provides new insights into the mechanisms driving TRP events in Eastern China, highlighting the crucial role of TC activity and its feedback effects on large-scale circulation.
• The findings contribute to a better understanding of the complex relationships between tropical cyclones and regional precipitation patterns.
