by ZAMG


17 April 1996/06.00 UTC - Meteosat IR image; weather events (green: rain and showers, blue: drizzle, cyan: snow, purple: freezing rain, red: thunderstorm with precipitation, orange: hail, black: no actual precipitation or thunderstorm with precipitation)
There are two main cloud configurations which are analysed in this case study:

Weather reports show that the leading part of the frontal cloud band is free of precipitation, but that there are broad areas of precipitation, especially in the two substructures mentioned above. Weather activity is more severe there. The second cloud system is located over the Atlantic, therefore no weather reports exist.

The SatRep diagnosis of this case identifies the areas already mentioned by "KF" (Cold Front) and "Welle" (Wave), but reveals, especially for the southern part which is discussed under the "special investigation", some more details. These include, for instance, "KF in KLA" which is a Cold Front under the influence of cold advection (CA), and "Jet Verstaerkung" (Jet Intensification).
