The divergence is pictured as the dashed magenta lines in this set of images. Magenta solid is the convergence and that is what we are after in these images as they show near the surface where there is rising motions and where there is convection. Over Germany, France and Austria remnant CBs are marked by convergence and rising motions.

Over Germany, France and Austria remnant CBs are marked by convergence and rising motions.

Convection is about to start. Over Germany, France and Austria areas are marked by convergence and rising motions.
20th June 2006: 12UTC
Convection has started. Over Germany and Austria the still small CBs are marked by convergence around 925 hPa. marking the rising motions.
19th June 2006: 15UTC
Convection is under way and apart from the convection over the Eastern part of Austria all cells in the image are marked by converging movement at 925 hPa.

The convection over Central Europe has reached its climax. Over Germany, France, Switzerland and Austria large MCSs are marked by convergence around 925 hPa. marking the rising motions.
19th June 2006: 21UTC
Slight contrast to the previous image as over Germany the cells tend to die out. Further South in Austria and Switzerland still large MCSs are observed. Influenced by the Alps convergence is still observed at 925 hPa.
