Summary
A conceptual model of lee cyclogenesis is given which combines the commonly observed predominant features inherent in Alpine lee cyclogenesis, to be: blocking of cold air due to the Alps and progression of a potential vorticity maximum over the Alps. Numerical simulations of observed cases of Alpine lee cyclogenesis are carried out whose flow development turn out to bear close resemblance to this model. Therefore far-reaching conclusions are drawn.
