We conducted dynamic downscaling using the RegCM4.0 with 25 km of horizontal resolution over CORDEX-East Asia phase 2 domain for the current climate (1981-2005) and evaluated its performance using various reference datasets. The HadGEM2-AO with about 110 km of horizontal resolution provided by the Korea Meteorological Administration (KMA) was used as the forcing data of RegCM4.0. The RegCM4.0 generally well simulated the spatial patterns of temperature and precipitation by representing geographical and topographic conditions, compared with HadGEM2-AO. In particular, the warm biases in Mongolia, northern China, and Russia during summer and cold biases in Tibetan Plateau, Mongolia, northeast China, and northern India during winter were reduced. However, the systematic wet (dry) biases of summer precipitation in the most of model domain (South Korea) were still remained. It was associated with the southward shifting of low-level jet caused by the weakened North Western Pacific High in HadGEM2-AO. In South Korea, the RegCM4.0 showed a better performance than HadGEM2-AO in terms of the magnitude and spatial variability of both temperature and precipitation. In particular, the RegCM4.0 performed better in simulating the ratio of extreme precipitation over 100 mm/day to total precipitation than HadGEM2-AO. The RegCM4.0 reasonably reproduced the frequency and inter-annual variability of heavy rainfall, frost day, and tropical night over South Korea.
Abstract
We conducted dynamic downscaling using the RegCM4.0 with 25 km of horizontal resolution over CORDEX-East Asia phase 2 domain for the current climate (1981-2005) and evaluated its performance using various reference datasets. The HadGEM2-AO with about 110 km of horizontal resolution provided by the Korea Meteorological Administration (KMA) was used as the forcing data of RegCM4.0. The RegCM4.0 generally well simulated the spatial patterns of temperature and precipitation by representing geographical and topographic conditions, compared with HadGEM2-AO. In particular, the warm biases in Mongolia, northern China, and Russia during summer and cold biases in Tibetan Plateau, Mongolia, northeast China, and northern India during winter were reduced. However, the systematic wet (dry) biases of summer precipitation in the most of model domain (South Korea) were still remained. It was associated with the southward shifting of low-level jet caused by the weakened North Western Pacific High in HadGEM2-AO. In South Korea, the RegCM4.0 showed a better performance than HadGEM2-AO in terms of the magnitude and spatial variability of both temperature and precipitation. In particular, the RegCM4.0 performed better in simulating the ratio of extreme precipitation over 100 mm/day to total precipitation than HadGEM2-AO. The RegCM4.0 reasonably reproduced the frequency and inter-annual variability of heavy rainfall, frost day, and tropical night over South Korea.
