The evaluation of systematic error in the limited area model MM5v3.7 with different parameterization schemes for the atmospheric boundary layer, cumulus, radiation and microphysics is carried out in this work. Estimate is based on the comparison of model forecast variables versus reanalysis ERA40. Systematic error for major atmospheric prognostic variables is described in terms of diagnostics such as the lead-time evolution, spatial distribution, vertical profiles and spectra. Optimal sets of parameterizations schemes for different variables are proposed to use in numerical simulations.
