Integrated Analysis of Guerrilla Heavy Rainfall Life Cycle and Vortex Tubes by Using Multiple Types of Radars

Localized heavy rainfall which resulting from isolated cumulonimbus often brings severe human and economic damages. Nakakita et al. developed a prediction system for torrential rainfall using vertical vorticity in a first echo using X-band Polarimetric Doppler radar (X-band MP radar) and Katayama et al. implemented this system. Besides, research on vertical vortex tube structure has been conducted. Nakakita et al. showed that with the development of the cumulonimbus cloud, a vertical vorticity structure with positive and negative pairs is generated. In this study, we analyzed the cumulous cloud with updraft, vertical vorticity, and hydrometeor. As a result, we succeeded in observing the behavior of the vertical vortex tubes, updraft, and hydrometeor
