The aim of this paper is to answer the question why our weather prediction for Croatia failed on June 22, 1990? lt deals with the application of the meridional wind profile in estimating the direction of movement of a cyclone in a hydrodynamically unstable atmosphere. Nonlinear meridional variation of zonal flow - barotropic wind shear - has been proved to govern the movement of cyclones and to support their amplification in the vicinity of the inflexional parts of the zonal flow meridional profiles.
