Abstract

A method for optimum modelling of the earth's topography, corresponding to differing meteorological phenomena, is presented.

The optimum averaging scale for mountains in terms of orographic cyclo- and anti-cyclogenesis is shown to be of the order of 150 km. The use of larger or smaller averaging scales decreases the correlation between the degree of cyclo- and anti-cyclogenesis and the parameters which describe the orography.

A quantitative relation between orographic cyclo- and anti-cyclogenesis and the form of orography determined by the Laplacian ▽2 Z 0 of the terrain function Z 0 = Z 0(x, y) is presented.
