What does the new Meteosat-12 see on top of the storms that we couldn’t see before?

From only a rather short period of operational data use, it is already clear that Meteosat Third Generation (MTG) system will revolutionise severe storm analysis and prediction. High spatial (highlight is on the two solar channels with resolution of 500 m, and two IR channels that can scan at the unprecedented resolution at 1 km, namely IR 10.5 and IR3.8 channels), but also high spectral, radiometric and temporal resolution of MTG Flexible Combined Imager (FCI) reveals various storm-top features and microphysical properties of severe storms with the unprecedented details from Geostationary orbit. Appearance of wave structures on top of the storms, but also on many other cloud structures, seems to be much more frequently observed then with previous generation of Metesat imager – even in the temperature fields, using IR imagery. Overshooting tops with their shadows, Above-Anvil Cirrus Plume (AACP) detection (for the first time ever, even during nigh-time), and ability to see change of cloud phase and top temperature, presence of supercooled water, ingested aerosol particles into storm clouds, are highlights of advanced detection of FCI imager. The presentation will demonstrate how different storm-top features, and overall storm behaviour is analysed and interpreted through Level-1.5 images and RGB composites.
