Outline of Final Research Achievements

An integrated research has been conducted to reduce water related disasters caused by localized heavy rainfall and “guerrilla-heavy rainfall”. During the in-situ observations, newly developed videosonde system was utilized to understand the life stages of convective clouds by synchronizing it with the polarimetric radar. And, another fundamental observations toward understanding storm-genesis was started over heat-island urban, by utilizing multi-sensors observations. Valuable data collected during the in-situ observations provide important information to the consequent researches, such as numerical modeling of cumulonimbus cloud, developing a method of rainfall prediction, and establishing an earlier-alert system. The earlier detection and risk prediction system for guerrilla-heavy rainfall is under test operation by the River Bureau of Japan, for its practical utilization, which is one of our great contributions to the society and the related research area as well.
