• Detailed Analysis on Cumulus Cloud In Early Developing Stage by Using Phased Array Radar

抄録

Localized heavy rainfall which resulting from isolated cumulonimbus often brings severe human and economic damages. Nakakita et al.(2015) developed a prediction system for torrential rainfall using vertical vorticity in a first echo using by X-band Polarimetric Doppler radar. Besides, research on vortex tube structure in guerrilla heavy rainfall has been conducted. Nakakita et al. (2016) showed that with the development of the cumulonimbus cloud, a vertical vorticity structure with positive and negative pairs. Nakakita et al(2017) showed that there is also vertical vorticity structure with positive and negative pairs is generated in early developing stage. In this study, we analyzed the cumulous cloud with higher spational temporal resolution by using Phased Array Radar (PAR). As a result, we succeeded in observing the detail behavior of the vortex tube which cannot be captured by X-band MP radar.
