Sažetak
Recent model development of the ICTP regional climate model RegCM4 includes expansion of the model capabilities to the 1 km-10 km range of the spatial resolutions. Two main additions enable RegCM4 applications at these spatial scales: non-hydrostatic dynamical core and new microphysics parameterization. We will present results of the RegCM4 model applying new options over the Adriatic region, where three cases of the bora/bura events (November 1999, May 2005, February 2012) are simulated at horizontal resolutions of 3 km, nested into 12.5 km hydrostatic simulations forced by the ECMWF ERA- Interim reanalysis. Simulated wind speed and direction, temperature and humidity will be examined in relation to both SYNOP surface observation and radiosounding vertical profiles. Also, simulated total precipitation fields will be compared against EURO4M-APGD gridded observational product. In order to demonstrate added value of the new model capabilities, the impacts of hydrostatic and non-hydrostatic dynamical cores, but also of the default and new microphysics parameterizations will be discussed. Results of this study will provide supporting information concerning the planned longer (i.e., 10yr) non-hydrostatic simulations of both historical and future climate over the Adriatic region.
