Short Summary

This study develops a new fast and analytical model for the complete radial structure of tropical cyclone (TC) wind fields by combining an existing inner-core wind model, an outer wind model, and a modified Rankine vortex transition model, demonstrating its potential to reproduce the full range of simulated and observed TC winds without statistical fitting.

Objective

• To develop a new fast and analytical model for the complete radial structure of tropical cyclone (TC) wind fields by integrating existing inner-core and outer wind models with a modified Rankine vortex transition model.

Study Configuration

• Spatial Scale: From the inner core to the far outer region, covering the full radial extent of a tropical cyclone.
• Temporal Scale: Represents a quasi-steady state or instantaneous radial wind profile of a tropical cyclone.

Methodology and Data

• Models used:
  • Inner-core wind model: Tao et al. (2023, T23)
  • Outer wind model: Emanuel (2004, E04)
  • Transition model: Modified Rankine vortex
  • New combined model for complete radial TC wind field.
• Data sources: Simulated and observed tropical cyclone wind data (specific sources not detailed in the abstract).

Main Results

• The new wind model successfully combines the strengths of the T23 model (captures inner-core wind variation with small errors) and the E04 model (reproduces broad outer wind structure at large radii).
• The model is fast, analytical, and does not require statistical fitting.
• It shows great potential in reproducing the full range of simulated and observed tropical cyclone winds across all radial regions.

Contributions

• Development of a novel, fast, and analytical model for the complete radial structure of tropical cyclone wind fields.
• Seamless integration of high-performing inner-core and outer wind models using a modified Rankine vortex for transition, eliminating the need for statistical fitting.
• Provides a comprehensive and efficient tool for representing tropical cyclone wind fields from the inner core to the far outer region.
