Abstract

Detection of spatial representativeness of rainfall is important for the prevention of disaster. This study analyzed the spatial representativeness of rainfall based on observed data at the railway observational stations and the meteorological stations of Japan Meteorological Agency in Kanto Plain and the mountains region of Koshin-etsu. The results can be summarized as follows:<BR>The 95th percentile of the 1-hour (24-hour) precipitation ratio between two stations is about 1.5 (1.2) at the distance of two stations is one kilometer. The high spatial representativeness area of ordinary 1-hour (24-hour) precipitation is about five (ten) kilometers, and one of local 1-hour (24-hour) precipitation is about two (five) kilometers. The spatial representativeness is higher in the plain than in the mountainous region. The orographic effects become larger when the distance of two stations exceeds two kilometers.
