TFP:
There is a well developed TFP associated with the frontal cloud band over the Atlantic. Another branch of a TFP can be seen from England southward into the Bay of Biscay. This branch seems to be associated with an old frontal cloud band and reaches into the area of the Warm Sector Cbs. Although this gives the impression that the Cbs would be in a frontal zone, this secondary TFP branch is only a peculiarity of this particular case.
Equivalent Thickness:
In this configuration the warm sector is accompanied by a very big and pronounced thickness ridge. The Cbs are exactly in
the center of this ridge as it is in the ideal case.
Temperature Advection 700 hPa:
The field of temperature advection is not very distinct in the area of the Warm Sector Cbs. There is only weak WA. On the
other hand as this is the area of the warm sector big values of TA cannot be expected there. Consequently this parameter
is in accordance with the ideal configuration of this conceptual model.
Showalter Index:
The Showalter Index indicates a very unstable area associated with the Warm Sector Cbs. Values below zero indicate heavy thunderstorms. This agrees with the ideal conceptual model.
ΘE:
The very pronounced ridge in the field of equivalent potential temperature shows the warmest air in the area of the Warm
Sector Cbs which is necessary for this conceptual model.
