Abstract
In recent years, it has been pointed out that climate change due to global warming has effected to the scale and form of rainfall. In Japan, many regions have experienced floods, landslides from unusually intense rains, and much of the country has seen record-breaking rainfalls. By 20th August 2014 , the number and scale of rainfall, flood had already become so exceptional that caused major landslides in Hiroshima prefecture. In order to reduce the damage from such disasters, It is necessary to accurately grasp the characteristics of rainfall phenomenon, typhoons and torrential rains immediately. Understanding whether the meteorological phenomena change in short time will help finding the time constant of the turbulent component of rainfall time series to evaluate the uncertainty runoff discharge. Thus, an illustration the intensity and duration of rain events is critical to indicate the rainfall properties. This study analyses one minute rainrate by using the data from high rain-gauge of XRAIN and the work also caried out the research about characteristics of the periodic fluctuation.
