Evaluation of CESM/WRF climate simulations at high resolution over sumatra

This paper evaluates climate simulations at high resolution for Sumatra simulated using the Weather Research and Forecasting (WRF) model driven by climate simulations of the global climate model Community Earth System Model (CESM) version 1. CESM/WRF simulated climatological temperature and precipitation at 10-km resolution covering the 20-y period of 1980-1999 were evaluated using the University of East Anglia Climatic Research Unit, the University of Delaware Air Temperature and Precipitation, and the Global Precipitation Climate Center observation datasets, and the ERA-Interim reanalysis dataset. Results show that CESM/WRF performs much better than CESM does and can simulate local spatial patterns and values of precipitation and temperature for Sumatra well. CESM/WRF simulated climatological temperature and precipitation agree well with observations and reanalysis. CESM/WRF is useful for providing climate simulations at high resolution for Sumatra.
