RegCM4 nonhydrostatic simulation over the CORDEX FPS Convection domain

Applicability of the regional climate model RegCM4 was recently extended to the 1 km - 10 km range of the horizontal resolutions. We will present results of the RegCM4 model applying newly implemented (1) nonhydrostatic dynamical core and (2) cloud microphysics. In this setup, RegCM4 both hydrostatic and nonhydrostatic versions at the 3 km grid spacing over the CORDEX FPS Convection domain are nested into RegCM4 hydrostatic 12.5 km simulation over the EURO- CORDEX domain and forced by the ERA-Interim reanalysis. First, sensitivity study related to the dynamical core, cloud microphysics and vertical resolution will be summarized. Second, 1-year simulation over the CORDEX FPS Convection domain will be examined in comparison to EURO4M- APGD gridded observational product, SYNOP surface observations and radiosounding vertical profiles. Results of this study are basis for 10-year simulations planned in the scope of the CORDEX FPS Convection.
