Nowcasting of Severe Weather from Satellite Images for Northern Europe
Izolda Marcinoniene presents 2 case studies on severe thunderstorms over Poland and the Baltic States.
Length: 30 minutes.
Nowcasting of severe convective storms is still one of the most challenging tasks for operational forecasters. Satellite data are very useful in convection nowcasting because they enable a detailed monitoring of the various stages of convection; from the pre-convective environment to specific features on the tops of the mature convective clouds. Also, future MTG system will provide even better tools for convection nowcasting: satellite data with better temporal (every 2.5 min) and spatial resolution.
In this lecture, severe weather cases of 29 July 2012 and 30 July 2013 will be analysed by Izolda Marcinonienė (Lithuanian LHMS), mainly using MSG satellite images and ECMWF data. The first event includes a more expanded North-Eastern European area – from Poland (where the unstable situation started) towards the Baltic States (where the severe weather phenomena developed) to Finland (where they ended). The second event hit only Lithuania, but local very heavy rain reached even the disastrous phenomenon criteria and will be shortly presented as well.
