Abstract

 The probabilistic precipitation may have a difference due to the accumulation of observation data, but it is not taken into account in the design of soil structures. In this study, the difference of the probabilistic precipitation in a certain return period was investigated, using the observation data of the regional meteorological observatory and the surface metrological observatory. From the statistical analysis using the observation data of the regional metrological observatory, the area where the probable precipitation increases can be estimated. Furthermore, statistical analysis using surface metrological observatory data revealed an increase in probabilistic precipitation at specific points.
