The static stability and convective stability (for classification see: Hess, 1959) of the different layers are represented in Figure 7 by the profiles of virtual potential tempera- ture 9V and equivalent potential temperature 6e, respectively. In addition to the facts already mentioned, we find under undisturbed conditions that 9e decreases slightly up to the inversion base, and rather strongly in the inversion. Above the inversion to 700 mb, the equivalent potential temperature 6e is nearly constant or slightly increasing. 1202.
