EUMeTrain: Nowcasting CAL Module - Basic Nowcasting

Fronts

"Now after having diagnosed the frontal system and its synoptic scale eastward propagation path the concentration should be on small scale problems and changes. The advection and crossing of the cloud system of the front should be nowcasted for some of the big European cities: London - Paris - Munic - Vienna - Budapest."

 Basic Info  London  Paris  Munich  Vienna  Budapest
This is a three hourly sequence of enhanced IR images from 17 May 06/21 UTC till 19 May 06/06UTC. Enhancement of IR images means that groups of greyshades (cloud top temperatures) are coloured in special colours to enhance the visibility of cold/warm clouds. This is something completely different to the well known RGB images which are also coloured, but RGBs are combinations of different channels and the colours represent a combination of physical qualities of the different channels.
 

"Now after the examination of the satellite images of this case study try to answer the following table; what features of nowcasting can be answered for frontal cloud systems and to which extent from a sequence of basic IR images alone?"

  Answer Possible No answer possible, but some hints No answer possible
Arrival Time of Frontal Cloud
Low/High Multilevel cloud
Arrival of surface front line
Arrival time of rain area
Existence of implemented thunderstorms
Nowcasting of wave development
