Last in this series of ECMWF parameters. In the image the thermal front parameter (blue) and the relative topography (green) are superimposed on IR10.8 imagery.
Over Germany some TFP maxima are observed over the remnant CBs. The thermal advection induced by the rising motions is most likely causing this strong signal in the TFP. The thickness ridge over Central Europe in the warm sector is well pronounced.

The convection is about to start. Again over Germany and Austria some TFP maxima are observed. The thermal advection induced by the rising motions is most likely causing this strong signal in the TFP and again a sign of the soon to develop convection. The thickness ridge over Central Europe in the warm sector is well pronounced.

The convection has started in a thickness ridge located over Central Europe.

Convection has reached its climax. The cells themselves are marked by local TFP maxima. The thermal advection induced by the rising motions is most likely causing this strong signal in the TFP. The convection is all concentrated to the thickness ridge which is still well pronounced noticeable over Central Europe.

Marked by a pronounced TFP maximum a still large MCS is seen over Southern France. The thermal advection triggered by the rising motions is causing this signal. Over Germany and Austria the cells have mostly died out. Still located in the thickness ridge some remnant CBs are seen, flanked by small TFP maxima.
