在每年的台风季节，日本的暴雨造成的洪水破坏相当严重，每年都会造成人员死亡和严重破坏。此外，近年来日本局地暴雨和局地暴雨造成的严重灾害（洪涝灾害、滑坡灾害等）有所增加。日本国土交通省（Ministry of Land, Infrastructure, Transport and Tourism）于2012年2月开始在日本23个观测站运行X波段多参数雷达系统。X波段MP雷达系统的降雨观测比过去的C波段雷达更详细。然而，现在，X波段MP雷达数据的应用大多仅用于显示1分钟的降雨图像。日本气象厅提供的降雨情况（降雨强度）标准显示了1小时内降雨量的危险等级，这些累积降雨量的危险等级对灾害事件的估计非常重要。因此，在本研究中，开发了一个累积降雨量监测系统。累积雨量可在PC显示器或移动终端显示器上清晰显示。在1小时内观测到降雨量后，5分钟内就可以在网站上显示结果。结果表明，这是地方政府等监测降雨量信息，并向附近居民发出洪水警报和疏散命令的有效系统。
Flood damage due to heavy rain is quite severe in Japan during the annual typhoon season, which causes death and serious destruction every year. Moreover, serious damage (flood damage and landslide disaster, etc.) by localised torrential rains and local heavy rains has increased in Japan in recent years. The Ministry of Land, Infrastructure, Transport and Tourism of Japan started the operation of an X‐band Multi‐Parameter (MP) radar system in February 2012, at 23 observation stations in Japan. Rainfall observations by the X‐band MP radar system are more detailed than by the past C‐band radar. However, now, applications of X‐band MP radar data are mostly only for displaying 1‐min rainfall images. The Japan Meteorological Agency is providing a standard of the rain situation (strength of rain), which shows hazard levels of the rainfall amount in 1 h. Those hazard levels of the accumulated rainfall amount are quite important to estimate disaster events. Thus, in the present study, an accumulated rainfall amount monitoring system is developed. The accumulated rainfall amount can be clearly shown on a PC monitor or a mobile terminal monitor. It takes up to 5 min to show the results on the web site after having observed rainfall in 1 h. It was shown that this is an effective system for local governments, etc. to monitor rainfall amount information, and to give flood warnings and evacuation orders to residents in the vicinity.
