Short Summary

This study systematically investigates the evolution of tropical cyclone (TC)-related precipitation across East Asia during boreal summer under a global warming scenario, revealing a substantial 125.6% increase in total TC precipitation due to TC intensification, altered steering flows, and enhanced atmospheric moisture content.

Objective

• To conduct the first systematic investigation of tropical cyclone (TC)-related precipitation evolution across the entire East Asian continent during boreal summer under a global warming scenario.

Study Configuration

• Spatial Scale: Entire East Asian continent.
• Temporal Scale: Boreal summer under a future global warming scenario (SSP245).

Methodology and Data

• Models used: Pseudo-global-warming technique coupled with high-resolution Weather Research and Forecasting (WRF) model simulations.
• Data sources: 38 successfully simulated TCs selected from 111 historical cases based on rigorous validation criteria. TC core precipitation and TC-related remote precipitation identified through integrated vapour transport channel detection.

Main Results

• Total TC precipitation over East Asia is projected to increase by 125.6% relative to present conditions under the SSP245 scenario.
• These precipitation changes coincide with significant TC intensification.
• The western Pacific subtropical high (WPSH) shows a pronounced eastward retreat, fundamentally altering steering flow patterns.
• Altered steering flows promote deeper TC penetration into mainland China and increase Japanese landfall frequency.
• Enhanced atmospheric moisture content provides favourable thermodynamic conditions for rainfall intensification.

Contributions

• Presents the first systematic, continental-scale investigation of TC-related precipitation evolution across East Asia under a global warming scenario using the pseudo-global-warming technique.
• Quantifies the substantial amplification of total TC precipitation (125.6%) and links it to TC intensification, changes in the WPSH, and enhanced atmospheric moisture.
• Distinguishes between TC core and TC-related remote precipitation, providing a comprehensive view of future precipitation patterns.
