EBU-POM MODEL

Regional climate model used for dynamical downscaling is EBU-POM (Djurdjevic and Rajkovic, 2010). It is fully coupled atmospheric-ocean regional climate model. Its atmospheric part is version of NCEP's Eta model. Ocean part of the model is Princeton Ocean Model (POM). The coupling between the atmospheric and oceanic part is done explicitly, in a way that models exchange heat and momentum fluxes and sea surface temperature (SST) on every atmospheric physics time step (Djurdjevic and Rajkovic, 2008).

The model has been previously used for climate change integrations in the Euro-Mediterranean region within the SINTA project (Gualdi et al., 2008). These results have been used in the Initial National Communication of the Republic of Serbia (2011), as well as in several impact studies such as: Stojanovic et al., 2013; Ruml et al., 2012; Bellafiore et al., 2012; Krzic et al, 2011.

The RCM climate simulations domain is the Euro-Mediterranean region, with the center of the atmospheric part positioned on the coordinates 41.5°N, 15°E. The model boundaries are 19.9° versus east and west and 13.0° versus north and south from the center of the model. Oceanic part of the model covers the Mediterranean sea without the Black sea. The horizontal resolution of the atmospheric model is 0.25°, while in the vertical direction the model has 32 vertical levels. RCM simulations are done for the period 1950-2000 with an observed concentration of GHG, using the experiment 20c3m. The referent present climate period (base period) 1961-1990 is used in accordance to the WMO standard. Two simulations are performed for the future climate, both in the period 2001-2100, one under the A1B and other under the A2 IPCC/SRES scenario (Nakicenovic et al., 2000). The SRES A1B scenario, considered to be a standard future emissions scenario in many studies, is a mid-line scenario, while A2 is at the higher end of the SRES emissions scenarios.

For the initial and boundary conditions for the model simulations are used results from the global climate model ECHAM5 (Roeckner et al. 2003) coupled with MPI-OM ocean model. ECHAM5 model results are available at CERA database (http://cera-www.dkrz.de/).

In addition to the results of the model which may be downloaded through this data base additional variables from model output are available upon request. Contact details can be found here
