日本国家地球科学与灾害预防研究所(NIED)X波段偏振雷达(MP-X)观测到，2008年8月5日，日本东京的Toshima、Chiyoda、新宿和文京区发生局部性强降雨，造成5人死亡，34座房屋被淹。雷达资料的初步分析揭示了这次降雨过程的以下特征。短时间内，小范围内出现了强降雨。1小时累积降雨量大于50毫米和80毫米的范围分别约为20和5平方公里。11：30到13：30 LST的最大总降雨量(123毫米)出现在江户川小学上空。这场雷雨最初发展迅速。降雨开始后仅15分钟，降雨率就超过100 mm h-1，从11时55分到12时30分持续了35分钟。当地时间12：10左右，江户川小学上空的雨量计观测到了最大降雨量(153 mm h-1)。MP-X资料与地面雨量计资料的对比表明，MP-X比常规雷达提供了更准确的降雨信息，对局地暴雨的监测是有用的。
Localized heavy rainfall that occurred in the Toshima, Chiyoda, Shinjuku, and Bunkyo wards of Tokyo, Japan on 5 August 2008, causing 5 deaths and the flooding of 34 houses above floor level, was observed by the National Research Institute for Earth Science and Disaster Prevention (NIED) X-band polarimetric radar (MP-X). Preliminary analyses of the radar data reveal the following characteristics of the rainfall event. Heavy rainfall occurred in a small area over a short period. The extents of the areas over which 1-hour accumulated rainfall was greater than 50 and 80 mm were about 20 and 5 km2, respectively. The maximum total rainfall amount (123 mm) from 11:30 to 13:30 LST was observed by MP-X over Edogawa Elementary School. The thunderstorm initially developed rapidly. Only 15 minutes after the onset of rainfall, a precipitation rate in excess of 100 mm h-1 was observed, continuing for 35 minutes from 11:55 to 12:30 LST. The maximum rainfall rate (153 mm h-1) was observed by a rain-gauge over Edogawa Elementary School at around 12:10 LST. A comparison of MP-X data with surface rain-gauge data reveals that MP-X provides more accurate rainfall information than conventional radar, making it useful in monitoring localized heavy rainfall.
