| Research Abstract |
This study evaluated the precipitation output of the AGCM20 by comparing with the observed precipitation, considering the spatial resolution of the model and orographic effects of precipitation. The AGCM20 output has a limitation to show clear orographic effects mainly due to its 20-km resolution topographic data, and it shows low dependency on topographic elevation. It was able to understand the seasonal and regional characteristics of the AGCM20 output, and this information was very valuable when the AGCM20 output was utilized into climate change impact analysis in hydrologic fields.
