EUMeTrain: Rapid Cyclogenesis over Central Europe, 17-20 Nov 2004

Derived Parameters

Basic synoptic parameters like geopotential height at different pressure levels as seen in the chapter before cannot explain the entire synpotic development. Therefore satellite images in combination with other derived meteorological parameters are presented in this chapter.

The key parameters for a rapid cyclogenesis are:


Jets (Isotachs) + PVA 300 hPa, IR Images: time sequence
In this chapter the cloud configurations seen in IR images are related to isotachs and PVA. 6-hourly sequences are shown.


Temperature Advection 700 hPa, IR Images: time sequence
In this chapter the cloud configurations seen in IR images are related to temperature advection at 700 hPa. 6-hourly sequences are shown.


Height of PV=1 unit, WV Images: time sequence
In this chapter the cloud configurations seen in WV images are related to PV=1. 6-hourly sequences are shown.


Summary of the investigations in this chapter

The following conclusions can be drawn from the presented parameters:
