Description

On July 28 in 2008, fifty people were washed away and five people were killed by a flash flood of Toga River, Kobe in Japan. Size of the river basin is small, i.e. about 10 km2 and it is almost urbanized. The disaster was very tragic and caused by quite localized torrential rainfall that is called "Guerrilla-heavy-rainfall" in Japanese media. The rainfall was produced by an isolated cumulonimbus that grew rapidly. To prevent these disaster, Japanese government recently installed networks of X-band polarimeric Doppler radars over major urban areas in Japan. X-band radar is suitable to realize earlier and more detailed detection of the baby cell, because X-band radar has higher sensitivity and spatial resolution. This research is developing an advanced early detecting and warning systems by the full utilization of the X-band polarimetric radar network.
