Plain Language Summary

Doppler radar provides high-resolution wind measurements within tropical cyclones (TCs) for real-time monitoring and weather forecasting. Hurricane Matthew (2016) was observed by the ground-based single-Doppler and NOAA P-3 Hurricane Hunter airborne radar simultaneously, providing a novel opportunity to compare single- and multiple-Doppler wind retrieval techniques. Here, we improve the single-Doppler wind retrieval algorithm and show the pros and cons of each method for studying TC structure.

Key Figure

Azimuth and amplitude polar diagram of the temporal evolution of (a) maximum wavenumber 1 tangential wind amplitude and phase and (b) maximum wavenumber 2 tangential wind amplitude and phase in the inner eyewall (<18 km) derived from the GVTD single Doppler analysis from 1907 to 1940 UTC 6 October. The amplitude of the tangential wind component is denoted by the radius of each dot, with the phase denoted by the azimuth. The red dot in (a) and (b) indicates the starting time at 1907 UTC, and the temporal evolution follows the blue line.
