Abstract: Atmospheric stable airflow over a mesoscale mountain chain has been considered in order to provide an evaluation, based on isentropic analysis, of the base height of the upwind flow layer passing over the mountains. The ...

Abstract: Fourth-order moments of vertical velocity in the convective boundary layer (CBL) are seldom available because the unsteady nature of atmospheric flows makes time statistics unreliable for the evaluation of high-order ...

Abstract: The inertia of particles is the basis of the present model of particle ?dry deposition? from a turbulent fluid. The basic physical concepts of particle thermal motion as described by Einstein are herein extended to describe ...

Abstract: Spray, a 3D Lagrangian particle model for the simulation of complex flow dispersion, is presented. Its performance is tested against the Environmental Protection Agency wind tunnel concentration distribution of passive ...
