Abstract
Abstract It is shown on the evidence of observational material that the simplifications necessary in order to derive the equation for the isallobaric wind are not justified, because the neglected terms in the equations of motion, viz., the convective terms and the local derivatives of the geostrophic deviation, are of the same order of magnitude as the terms retained in the equations. Hence the concept of the isallobaric wind has to be abandoned. Consequently the convergence ahead of moving cyclones and the divergence behind, in the lower troposphere, cannot be explained by means of the isallobaric-wind relation. It is shown that the distribution of the acceleration of motion in moving pressure systems offers an explanation of the observed distribution of convergence and divergence.
