Abstract: A large number of turbulence observations were made under stable conditions along a meteorological mast at Cabauw, The Netherlands. To present and organize these data we turn to the parameterized equations for the turbulent ...

Abstract: The laboratory experiments of Deardorff and Willis have shown that the dispersion from a low-level source under convective conditions follows mixed-layer similarity. The convective runs of the Prairie Grass dispersion ...

Abstract: The application of a self-similar profile in the integration of the temperature equation across the stable boundary layer leads to a rate equation for the inversion height. An analytic solution of the resulting equation ...

Abstract: A rate equation is derived which describes the development of the boundary-layer height under stable conditions as a function of time. It takes the form of a linear relaxation equation; its solution is forced toward an ...

Abstract: Using simulations with a large-eddy model we have studied the decay of convective turbulence in the atmospheric boundary layer when the upward surface sensible heat flux is suddenly stopped. The decay of turbulent kinetic ...

Abstract: With a large-eddy model the large-scale flow structure of the convective boundary layer is simulated in a box of (5 ? 5 ? 2) km. The calculation is run till the turbulence has reached a quasi-steady state. At that time we ...

Abstract: This paper discusses the results of a surface-layer experiment near the Cabauw meteorological mast. We measured momentum, heat and moisture fluxes at two heights, namely, 3.5 and 22.5 m. The measurements also include the ...

Abstract: Results are presented from a large eddy simulation (LES) and wind tunnel study of the turbulence regime in a horizontally evolving sheared atmospheric convective boundary layer (CBL) capped by a temperature inversion. The ...

Abstract: Modifications of turbulence regime in the sheared convective boundary layer (CBL) by a number of external nonbuoyant forcings are studied experimentally in a thermally stratified wind tunnel and numerically by means of ...

Abstract: A model is developed to describe the dispersion of pollutants in a coastal area when stable air masses are transported inland. It is assumed that a convective mixed layer develops over land, the height of which increases ...
