Spectral Methods for Atmospheric Diffusion Modeling The turbulent diffusion process is scale-dependent. The gradient-transfer theory (K-theory) is only appropriate when the dimensions of the dispersed material are much larger than the size of the turbulent eddies. Introduction of a spectral turbulent diffusivity function (STD) makes it possible to t

Physical Modelling of Flow and Dispersion over Complex Terrainpendent upon three general sets of variables. These are variables that describe topographic geometry, synoptic-scale winds and surface-air temperature distributions. In addition, pollutant concentration distributions also depend upon location and physical characteristics of the pollutant source. Ove

On the Enhanced Smoothing over Topography in Some Mesometeorological Modelsorological flow models. The starting point is the horizontal equation of motion in its “flux-form” in the σ-system in which we replace (following Reynolds’ procedure) the velocity components u.v and σ as well as other relevant quantities by terms of the form ., etc. (ū = time average of u; u. = fluc

Mesoscale Flow over Complex Terrain — A Field Study in the Lake Kinneret Areasoscale flow patterns in and around the lake valley and compare them with the results of mesoscale model simulations in the same area. The main effort of the program was directed to the determination of three dimensional trajectories from various points around the valley. For that purpose a new meth

Experimental and Model Transport and Diffusion Studies in Complex Terrain with Emphasis on Tracer Stal Laboratory program devoted to developing a better physical understanding of atmospheric boundary layer flows in areas of complex terrain. The first technical challenge undertaken by the program was an investigation of atmospheric boundary layer phenomena associated with the development, continuat

The Wind Regime in Coastal Areas with Special Reference to Results Obtained from the Swedish Wind Enn. The studies include the change with distance inland of mean wind structure as well as the turbulence structure in various conditions. It is found that wind spectra are usually well described by local similarity in its high frequency part, even in complex terrain. The low frequency parts of the sp

We discuss the consequences of this expression for the dispersion of a point source emission. We find that the time scale of diffusion in this case is about 5 hours.

Daily Practices for Mindful Exercisessumption of well-mixedness of first-order moments of conservative variables is not valid for all quantities. A simple similarity relation for the inclusion of the effect of entrainment on the shape of the vertical profiles is given.

Two mass consistent programs are described, the first based on the parametric representation of one of the wind components, and the second based on a few wind measurements and a variational principle. To verify the reliability of the vari.ational approach, a measurement program rela
