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
Thank you for your attention
