A barotropic planetary boundary layer
Boundary-Layer Meteorology, 1983The temperature and wind profiles in the planetary boundary layer (PBL) are investigated. Assuming stationary and homogeneous conditions, the turbulent state in the PBL is uniquely determined by the external Rossby number and the stratification parameters. In this study, a simple two-layer barotropic model is proposed. It consists of a surface (SL) and

Frontal Substructures Within the Planetary Boundary Layer
Boundary-Layer Meteorology, 1996A two-dimensional mesoscale model, extended by a TKE closure for the subgrid-scale terms and coupled with a soil model, is used to investigate the role of the Planetary Boundary Layer (PBL) for the development and the substructures of two different types of cold fronts.

The term planetary boundary layer (PBL) is often used as a synonym for the Ekman layer (i.e., for the region in which the convergence of the vertical flux of momentum is of the same order as the Coriolis force and the pressure gradient). The definition favored in this chapter is somewhat broader and includes the regions on both sides of the interface ...

It is natural to think that the atmosphere rotates with the same velocity as the solid Earth although it is not at all obvious why this should happen. In general, we could say that the Earth drags the atmosphere because of the friction between the surface and the atmospheric layers near it.

Molecules in Boundary Layers in Planetary Nebulae
Astrophysics and Space Science, 1997Newly formed planetary nebulae are very interesting objects for the astro-chemist to study, since they appear to involve the interaction of a dense, molecule-rich superwind with the UV field and fast wind from the revealed central star. In the simplest picture each of these winds has shocked and unshocked components but the fast wind remains wholly ...

Publisher Summary The planetary boundary layer (PBL) is that part of the atmosphere that is affected by the characteristics of the ground by rapid vertical exchange processes, mostly by turbulence. Its characteristics vary strongly from day to night and from land to sea.

Turbulence structure in the planetary boundary layer
Boundary-Layer Meteorology, 1973This review of the last three years of progress in the understanding of wind profiles and the structure of turbulence in the planetary boundary layer is divided into three parts. The first part, by N. E. Busch, deals with the atmospheric surface layer below 30 m.
