Beskrivning

The 35th OHOLO Conference, which provided the basis for the present book covered a broad range of topics. Basic studies and newly developed methods in modeling atmospheric flows are discussed, besides analyses of concentration fluctuations in different atmospheric conditions, and techniques of data acquisition. The book gives state-of-the-art impression of the situation in turbulent diffusion and transport.

Innehållsförteckning

Part 1 Basic studies and novel methods in modeling atmospheric flows - uncertainties in air quality model predictions; review of non-local mixing in turbulent atmospheres - transilient turbulence theory; buoyant plume rise in a lagrangian framework; mixing efficiency of a stably stratified fluid; possibility of simulating geophysical flow phenomena by laboratory experiments; investigation of the planetary boundary layer height variations over complex terrain; the importance of mesoscale phenomena on the dispersion of pollutants in the vicinity of a point-source emission; a numerical model for estimation of the diurnal fluctuation of the inversion height due to a sea breeze; synoptic and mesoscale, weather conditions during air pollution episodes in Athens, Greece; the use of a meso-gamma scale model for evaluation of pollution concentration over an industrial region in Israel (Hadera). Part 2 Analysis of concentration fluctuations - recent developments in the lagrangian stochastic theory of turbulent dispersion; a three-dimensional model for calculating the concentration distribution in inhomogeneous turbulence; fluctuations of line integrated concentrations across plume diffusion in grid generated turbulence and in shear flow; the structure and magnitude of concentration fluctuations. Dispersion in sheared gaussian homogeneous turbulence; fractal aspects of integrated concentration fluctuations; modeling nitrogen oxide conversion by using probability density functions. Part 3 Experimental techniques and methods of data acquisition - final results of the condors convective diffusion experiment; one-dimensional wind profile model with stability and Eddy Viscosity estimations from sodar data; intercomparison of turbulence data measured by sodar and sonic anemometers; lidar measurements of plume statistics; laboratory study of the turbulent structure of a channel jet flowing into an open basin; limitation of using multi-type sensors in combination for verifying atmospheric phenomena; observations of the diurnal oscillation of the inversion over the Israeli Coast; spatial structure of a jet flow at a river mouth; actinic fluxes - the role of clouds in photodissociation. Part 4 Round table discussion - round table discussion - interactions and feedback between theory and experiment; author index.
