CONSIDERATION OF THE RAINFALL FACTOR FOR THE SIMULATION METHOD OF EXTREME RAINFALL EVENTS USING XRAIN AND APPLY FOR NON-OBSERVATION AREA

Abstract

 To calculate the return period of previous heavy rainfall events and to simulate rainfall data under a future climate, AMeDAS analyzed rainfall data for the 28th year is used in previous studies. XRAIN data that corrected using DPR data on the core satellite of the GPM mission is used in this author’s previous study, we generate the extreme rainfall events. However, the data used for calculation is for 3 years, it is not enough compared to the previous study. In this study, we improve the analysis method to obtain the favorable result when the observation data is not enough in the focusing area. And the improve analysis method is applied in Kochi area where observation data is not exist.
