Boundary Layers in Planetary Atmospheres
1973In large-scale air currents, near the surface of a planet, the combined action of the pressure gradient, turbulent friction and Coriolis force results in the formation of the atmospheric boundary layer. Unlike most boundary layers dealt with in aerodynamical engineering, the atmospheric boundary layer is characterized by the influence of the Coriolis ...

Stratocumulus-Topped Atmospheric Planetary Boundary Layer
1998Marine stratocumulus often occurs over the subtropical oceans off the west coasts of the major continents throughout most of the summertime season when the large-scale subsiding motion is strong and the ocean surface is cold. This large-scale condition leads to a very moist, shallow planetary boundary layer (PBL).

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 ...

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.

Surface and Planetary Boundary-Layer Modelling of Stably Stratified Atmospheric Boundary Layers
1999Abstract For surface layer (0-lOOm height) studies of stable stratified flow over topography, the conventional constant flux layer flows with log-linear profiles for velocity and potential temperature or density are unsuitable as they stand, since velocity linearly increases with height.

Planetary boundary layer and turbulence parameterizations
2007Introduction We have seen how the various properties of the land surface can influence the fluxes of energy that occur in the atmospheric surface layer. Now that these boundary conditions have been described, the next step is to determine how these energy fluxes influence the evolution of the atmosphere.

The surface roughness and planetary boundary layer
pure and applied geophysics, 1980Applications of the entrainment process to layers at the boundary, which meet the self similarity requirements of the logarithmic profile, have been studied. By accepting that turbulence has dominating scales related in scale length to the height above the surface, a layer structure is postulated wherein exchange is rapid enough to keep the layers ...

Airplane Measurements of Planetary Boundary Layer Structure
Journal of Applied Meteorology, 1970Abstract Measurements of air velocity and temperature from an airplane in the planetary boundary layer with strong surface heating are used to calculate vertical heat, momentum and energy fluxes, as well as spectral densities and probability distributions of velocity and temperature.

Lectures on the Planetary Boundary Layer
1983There have been a few such workshops and short courses on aspects of boundary-layer meteorology over the past decade, so that a lecturer today must consider carefully where to start. I have decided to try to bring a contemporary view to my lectures, which means I will not be able to cover some older and now well-understood topics.
