Recently, we have added some improvements about the simulation of the plume rise phenomenon to SAFE_AIR, a code simulating the transport and diffusion of airborne pollutants. This code is based on the advection of Gaussian segments and puffs driven by a 3D diagnostic wind model and is able to deal with both non-stationary and non-homogeneous conditions. We have evaluated this new version of the SAFE_AIR code against the Kincaid data set. Here we present the results obtained simulating the plume rise phenomenon using both the formulae recommended by Briggs and the Moore method, and applying three different options to simulate the interaction between the plume and thermal discontinuities in each of the two cases.

Abstract
Recently, we have added some improvements about the simulation of the plume rise phenomenon to SAFE_AIR, a code simulating the transport and diffusion of airborne pollutants. This code is based on the advection of Gaussian segments and puffs driven by a 3D diagnostic wind model and is able to deal with both non-stationary and non-homogeneous conditions. We have evaluated this new version of the SAFE_AIR code against the Kincaid data set. Here we present the results obtained simulating the plume rise phenomenon using both the formulae recommended by Briggs and the Moore method, and applying three different options to simulate the interaction between the plume and thermal discontinuities in each of the two cases.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
