Assessment of atmospheric dispersion from ANPP hypothetical accident based on Fukushima accident by HYSPLIT model
The atmospheric dispersion of Materials is one of the most important ways of spreading contamination of a NPP accident. In this study, the particle paths were calculated by HYSPLIT model (both pressure and AGL form of trajectory) horizontally and vertically at 0 and 1.5 meters above ground level during 15-day periods for 23& 24 November 2006 start times. Then, the releases values of Fukushima a...
متن کاملSensitivity of atmospheric dispersion simulations by HYSPLIT to the meteorological predictions from a meso-scale model
Mesoscale transport and dispersion of air pollutants from a few major point sources in the Mississippi Gulf coastal region is calculated using a coupled modeling system consisting of the atmospheric dynamical model WRF and the lagrangian particle model HYSPLIT. The sensitivity of the dispersion model results to the meteorological fields is studied by conducting an ensemble of simulations using ...
متن کاملIdentification of regional atmospheric PM10 transport pathways using HYSPLIT, MM5-CMAQ and synoptic pressure pattern analysis
Air pollution in urban cites is caused not only by local emission sources but also significantly by regional atmospheric pollutant transport from surrounding areas. This study is to identify regional atmospheric PM10 transport pathways through an integrated modeling and synoptic pressure pattern analysis approach with a case study in Beijing, northern China. Beijing is a city sensitive to trans...
متن کاملThe Mathematics of Atmospheric Dispersion Modeling
The Gaussian plume model is a standard approach for studying the transport of airborne contaminants due to turbulent diffusion and advection by the wind. This paper reviews the assumptions underlying the model, its derivation from the advection-diffusion equation, and the key properties of the plume solution. The results are then applied to solving an inverse problem in which emission source ra...
متن کاملAtmospheric dispersion modeling and health effects of PM2.5 released from automotive industries (case study of Saipa)
Background: Air pollution is one of the most important environmental problems and various industries are sources of air pollutants, especially particulate matter. The purpose of this study is to evaluate the health effects of particulate matter released in the automotive industry. Methods: In this research, after measuring the concentrations with the WESTECH, monthly during 2021, the distributi...
