KAPITOLA ABSTRACT Abstract Topic of Mc. S. Thesis: Evaluation of information from Meteosat 8 and the CZRAD network of meteorological radars in selected significant convective situations. Abstract: This paper focused on comparing the information from the satellite Meteosat 8 and the CZRAD network of meteorological radars in selected significant convective situations. The main goals of this study were to assess how satellite and radar data respond on development of convection and if the satellite data responds on intenzifying convection before the radar data. For this purpose, four significant convective situations and associated areas (72 x 72 km) were selected, and the satellite and radar data were preprocessed. Appropriate differences of spectral channels (i.e. satellite methods) and radar products were chosen. The preprocessing involved data synchronization in time and location. The parallax correction was used for satellite data. Seven satellite methods were used - spectral channel IR 10.8 (TIR10.8), difference of channels WV 0.6 and IR 10.8 (TWV6.2 - TIR10.8), IR 13.4 and IR10.8 (TIR13.4 - TIR10.8), IR 12.0 and IR 10.8 (TIR12.0 - TIR10.8), IR 8.7 and IR 10.8 (TIR8.7 - TIR10.8,), NIR 1.6 and VIS 0.6 (REFNIR1.6 - REFVIS0.6) and the trispectral method. The trispectral method resulted from measurements of...
