Abstract

In this study, we estimated spatial representativeness of band-shaped heavy rainfall area using variogram. We analyzed Northen Kyushu Heavy Rainfalls in 2012 and 2017, and Heavy Rainfall in July 2020. We found range of variogram was large when band-shaped heavy rainfall area prevailed in wide area, and vice versa. In addition, hole effect clearly appeared when intense band-shaped rainfall area was formed.
