Abstract
This study evaluated RCP scenario's daily precipitation data from the regional climate model and proposed the calibration method of RCP data for hazard mitigation field. Three data, observed daily precipitation in 2001~2013, RCP scenario's daily precipitation in same period with observed data, and RCP scenario's daily precipitation in 2014~2100, was applied to examine the statistical characteristics of each data. As a result, it found that RCP scenario's data properly reflected climate characteristics in the Korean Peninsula for annual precipitation and monthly precipitation distribution, except number of days with precipitation overestimated. To calibrate the problem, this study proposed the method which daily precipitation less than a threshold (0.6~1.7 mm) is considered as no rain. The result after calibration has shown that calibrated RCP scenario's data properly reflected climate characteristics in the Korean Peninsula for annual average number of days with precipitation and the distribution of monthly number of days with precipitation.
