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

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 ...

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.

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.

The thickness of the planetary boundary layer
Atmospheric Environment (1967), 1969Many different methods for estimating the thickness H of the planetary boundary layer are summarized and applied to the 1953 O'Neill boundary layer observations. The observed variation of the thickness H is best explained by Latkhtman's (1961) formula, which states that H is directly proportional to the free-stream or geostrophic wind speed and ...

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.

Helical Circulations in the Planetary Boundary Layer
The Physics of Fluids, 1967Constant volume balloon (tetroon) flights within the planetary boundary layer provide evidence for the existence of alternating, horizontal roll vortices with axes in the general direction of the mean flow. The dimensions of these vortices are a function of stability.

The Flow in the Planetary Boundary Layer
1983Publisher Summary This chapter describes the flow in the planetary boundary layer (PBL). The investigations of the flow in the PBL are frequently preoccupied with the trees represented by turbulent eddies. Elaborate instrumentation and techniques have been developed for measuring, counting, categorizing, and averaging the turbulence in various ways ...

Slant-Path Scintillation in the Planetary Boundary Layer
Applied Optics, 1973Results are presented from an experimental study of the effects of range, path geometry, and thermal turbulence intensity in the planetary boundary layer on the laser scintillation magnitude, represented by the log-intensity standard deviation sigma. Intensity fluctuations of two 15-mW helium-neon laser beams propagating along reciprocal slant paths ...

The Planetary Boundary Layer of Mars
2019Abstract The planetary boundary layer of Mars is a crucial component of the Martian climate and meteorology, as well as a key driver of the surface-atmosphere exchanges on Mars. As such, it is explored by several landers and orbiters; high-resolution atmospheric modeling is used to interpret the measurements by those spacecrafts.
