The geostrophic stream function [psi] is defined at levels [p.sub.1] and [p.sub.2], [psi]([p.sub.1]) = and [psi]([p.sub.2]) = [[psi].sub.2], where the quasi- geostrophic vorticity equation for the mid-latitude [beta]-plane (7)-(8) is applied, while the vertical velocity w is specified at level [p.sub.1.5], where the thermodynamic energy equation (9) is valid.
[36] that the upper levels (500 hPa) maximum intensity and size of the explosive cyclones and the maximum geostrophic vorticity at 500 hPa in the Mediterranean are formed at the same area.
