Sažetak
The convective available potential energy (CAPE) can be calculated from radio sounding data or from outputs of numerical weather prediction model. Comparison of values of CAPE obtained in these two ways reveled that there are errors in model's CAPE. By replacing data at lowest level of the model by measured data CAPE was calculated that has excellent agreement with measured CAPE. This gives us opportunity do make accurate and detailed maps of CAPE combining model outputs with data from synoptic station. The accuracy of such maps is confirmed by radar images of 30 May 2001 thunderstorms.
