The main aim of the 3-year (2005-2007) CaliM&Ro project is interpolation of the single-site four-variable stochastic daily weather generator (WG) Met&Roll. The paper gives the sample results obtained during the first year of the project. The experiments are based on daily weather series from 45 Czech stations. WG parameters are interpolated using the nearest neighbours method with accounting for the effect of the altitude. Observed weather series and synthetic weather series produced by site-calibrated and interpolated WGs are (a) analysed in terms of the frequency of heat waves and cold waves, and (b) fed into the WOFOST crop growth model with model crop yields being analysed thereafter. Two validation tests are made: (a) Performance of WG is validated by comparing characteristics (heat and cold wave frequencies and the model crop yields) obtained with the site-calibrated WG with those obtained with observed weather series.
