Implementing a single-Doppler radar technique for tropical cyclones and integrating radar-derived wind fields into H*Wind surface analyses

The implementation of a single-Doppler radar technique for tropical cyclones is discussed. The radar-derived wind fields are integrated into H*wind surface analysis. A wind retrieval scheme, Ground-Based velocity Track Display (GBVTD), is developed to deduce the tropical cyclone's inner-core wind fields at a specified altitude. The method uses single Doppler velocity data from a single radar to deduce the tropical cyclone's primary circulation. The features in the wind field are determined up to a wave number three. It is found that most of the variance is explained by the wave number zero and one.
