## Abstract This study examines the influence of weak horizontal advections of momentum on a wellβmixed planetary boundary layer. In the simple flow system examined, the direction and magnitude of flow modifications depend on the Rossby number, the nondimensional surface drag coefficient and the or

A model of a stationary planetary boundary layer is proposed based on the equation of motion with the advective term retained. The latter is modeled by means of the so-called geostrophic momentum approximation in two versions -original and modified. New expressions for the vertical velocity W, at th
A bulk boundary-layer model is developed to predict surface fluxes and conditions in the well-mixed layer between the surface and the lower troposphere. The model includes the effects of all the dominant processes, including advection, in a dry boundary layer. The numerical model is compared with th
Within the framework of a mixed layer (ML) containing a zero-order jump, the concept of ML is generalized for the case of horizontal non-homogeneity on the assumption that not only potential temperature, but also the wind does not change with height. It turns out that the components of the vertical
