Introduction 3-1. PAWR Observation Range 4-1. Data processing system ・ In Japan, severe weather disasters caused by localized heavy rainfalls or tornadoes have occurred frequently in the last several years. ・ Although it is important to measure three dimensional structure of the rapidly developed severe storms, a volume scan by a parabolic antenna requires substantial time of more than 5 minutes. 0400JST, Aug 14 2012 Flash flood in the Toga river, Kobe （28 July 2008） 60 km (radius) The observation area of MLIT C-band radar and X-band MP radar (small blue circles). Kyoto Uji F2 tornado in Tsukuba （6 may 2012） Suita Akashi Kobe Invisibleregion Nara Invisible region Big radar observation Osaka Bay < Observation mode and data size / data rate > 3-dim measurement using a parabolic antenna (5-10 min) 3-dim measurement using phased array radar (10-30 sec) Kansai Airport Small radar network observation 3-2. Back-building localized heavy rainfalls around Uji (Aug 14, 2012) < Evolution of cumulonimbus > 0400JST 4-2. Publication (http://pawr.nict.go.jp) < Real-time data > < Past data > 2. 3-dim precipitation distribution in isolated cumulonimbus (July 26, 2012) 17:36:16 17:34:16 17:32:16 17:30:16 3-3. Stationary line-shaped rain- falls (18:51:20JST, July 22, 2012) 5. Summary 12 km 17:44:16JST 17:42:16 17:40:16 17:38:16 • We showed some localized heavy rainfall events observed phased array weather radar using 3-dim visualization. • We have developed real-time data processing system and are at work on creating the web page. 10 km 40 km 5 km
