Three-dimensional wind fields that can be estimated from meteorological radar data are useful for short-time rainfall prediction such as localized torrential rainfall. In this study, horizontal and vertical wind fields were estimated by the VVP method and the Dual Doppler analysis using three-dimensional high-density observation data obtained by dualpol phased-array weather radar. The results showed that the frequency of weak winds decreases and the frequency of strong winds increases as the elevation density of the input data increases. The estimated wind speeds also showed a smaller scatter. Furthermore, the estimated vertical winds from the Dual Doppler analysis showed less variation than those estimated by the VVP method.
