Global and regional climate projection by KEI climate simulator
Global and regional climate projection by KEI climate simulator
CMIP5 (Coupled Model Intercomparison Project) is in progress centered on WCRP (World Climate Research Programme) to support studies on the climate change effect and related policy making.
Those global scale RCP scenarios could be used for regional climate policy by various downscaling technique. KEI produces global scale climate projection from Community Earth System Model (CESM) by National Center for Atmospheric Research (NCAR) and regional scale climate projection over Korea dynamically downscaled by Weather and Research Forecast (WRF) model (Seo et al., 2013; Shim et al., 2017). The downscaled climate projection here is physically reasonable and now is being corrected with ground observation. We now distribute the main climate parameters (surface temperature, precipitation, RH, etc) and please send email to cshim@kei.re.kr to ask a set of climate data and any further cooperation.

The CESM global climate projection were conducted from 2006 to 2099 and that includes all climate scenarios (RCP 2.6, 4.5, 6.0 and 8.5). The spatial resolution is 1.9 degree by 2.5 degree (lat x long)

To dynamically downscale the CESM results, the meteorological variables from the CESM model were used as the initial and boundary conditions for the Weather Research and Forecast (WRF v3.3) model at 6-hour intervals to produce regional scale scenarios with a 7.5 × 7.5-km spatial resolution for the Korean Peninsula from 2006–2100. The detailed methodology for the dynamical downscaling has been reported previously by Seo et al. (2013).
Above figures represented the climate projection (surface temperature) with 7.5km spatial scale over Korean Peninsular. Our downscaling the latest climate change scenario has been applied for Indochina peninsular, and Bhutan for international cooperation.
