| Popis: | Recently, localized heavy-rainfall disasters in an urban area, which is called Guerrilla Heavy-rainfall", have been gotten a lot of attention in our country since flash flood at Toga river in Hyogo prefecture on 2008. In order to prevent such flash flood damages, X-band Multi Parameter radars (X-MP radars) are equipped near urban areas in Japan recently. In this study, we developed early detection and risk prediction system using X-MP radars. And now, we are trying upgrading this system by exploring the quantitative relationship between rainfall intensity and vertical vorticity in the cumulonimbus calculated from Doppler velocity, which is observed X-MP radars directly." |
