Conclusion Walawender J. – ‘Convective supercells over Europe, case study - May 26, 2009’ Satellite data are very useful to observe development of convective processes in the atmosphere Presented satellite products give possibility to: detect unstable atmospheric conditions early recognise and analyse complex processes of convection assess the potential of convection processes Use of presented satellite products can improve operational storm prediction and monitoring
