Projection of Korean Probable Maximum Precipitation under Future Climate Change Scenarios

الملخص EN

According to the IPCC Fifth Assessment Report, air temperature and humidity of the future are expected to gradually increase over the current.

In this study, future PMPs are estimated by using future dew point temperature projection data which are obtained from RCM data provided by the Korea Meteorological Administration.

First, bias included in future dew point temperature projection data which is provided on a daily basis is corrected through a quantile-mapping method.

Next, using a scale-invariance technique, 12-hour duration 100-year return period dew point temperatures which are essential input data for PMPs estimation are estimated from bias-corrected future dew point temperature data.

After estimating future PMPs, it can be shown that PMPs in all future climate change scenarios (AR5 RCP2.6, RCP 4.5, RCP 6.0, and RCP 8.5) are very likely to increase.
