Evolution of cloud top properties of severe convective storms over complex topography from the MSG perspective

Popis výsledku v původním jazyce

Deep convective clouds are very often initiated by mountain ranges due to mechanical uplift and also due to enhanced heat sources that drive upslope flow. After crossing the mountain range, convective clouds usually develops further and the intensity of convective storms increases. These processes have been well documented by radar observations as well as numerical simulations but only few papers used satellite measurements in geostationary orbit. This is because such measurements have limited horizontal and temporal resolution, which does not allow more detailed observations of the evolution of convective cloud tops over complex topography. On the other hand, the Flexible Combined Imager (FCI) on board new meteorological satellite in geostationary orbit Meteosat Third Generation (MTG) is expected to provide more detailed information on cloud top properties due to its high horizontal and temporal resolution measurements. This is particularly important in the detection and monitoring of severe convective storms whose cloud tops evolve rapidly in time. In this contribution, we will use new high-resolution MTG data to evaluate the cloud top properties of severe convective storms when crossing mountain ranges. Selected case studies will be analyzed to investigate the evolution of cloud top properties (e.g., overshooting tops, cold U/V) from mountainous regions towards lowland areas to observe the manifestations of possible intensification of convective storms. Satellite measurements in different spectral channels along with their differences, will be used to study the cloud top evolution. A comparison of FCI and SEVIRI (Spinning Enhanced Visible and Infrared Imager) measurements of cloud tops will also be presented and discussed. We will focus mainly on European mountain ranges, but due to the short measurement period, some case studies from other parts of the world may also be included.
