Short Summary

This study investigates Lifetime Maximum Intensity (LMI) trends in the South China Sea (SCS) since the 1980s, revealing a significant increase in LMI amplitude driven by opposing trends in local and migratory tropical cyclones, attributed to shifts in genesis, track, and environmental conditions.

Objective

• To investigate the trends and drivers of Lifetime Maximum Intensity (LMI) of tropical cyclones in the South China Sea (SCS).

Study Configuration

• Spatial Scale: South China Sea (SCS), Western North Pacific (WNP), Luzon Strait.
• Temporal Scale: Since the 1980s.

Methodology and Data

• Models used: Not explicitly mentioned in the abstract.
• Data sources: Not explicitly mentioned in the abstract, but implies analysis of tropical cyclone intensity and track data.

Main Results

• A significant increase in Lifetime Maximum Intensity (LMI) amplitude has been observed in the South China Sea (SCS) since the 1980s.
• This increase is driven by a decrease in LMI of local tropical cyclones (TCs) and an increase in LMI of migratory TCs originating from the western North Pacific.
• A westward shift in local TC genesis led to increased land constraints, suppressing TC development and weakening their LMI.
• Poleward migration of TC tracks facilitated increased entry of storms into the SCS through the Luzon Strait with minimal land interaction, thereby enhancing the LMI of migratory TCs.
• Favorable environmental conditions contribute to an increased frequency of rapid intensification events, further boosting LMI.

Contributions

• Provides the first detailed analysis of Lifetime Maximum Intensity (LMI) trends in the South China Sea (SCS) and their underlying drivers.
• Identifies the contrasting roles of local versus migratory tropical cyclones in shaping the overall LMI amplitude in the SCS.
• Attributes LMI changes to shifts in TC genesis locations, track patterns, and favorable environmental conditions.
• Highlights the growing potential impact of tropical cyclones on countries and regions surrounding the SCS.
