Application of a prognostic model TAPM to sea-breeze flows, surface concentrations, and fumigating plumes

摘要: Abstract We apply The Air Pollution Model (TAPM) (version 2.0), a three-dimensional prognostic model developed as tool to predict both meteorological and air pollution fields for environmental impact assessments related studies, data from the 1995 Kwinana Coastal Fumigation Study. field study was conducted over 12-day summer period in coastal region of Western Australia order investigate local sea-breeze meteorology, footprint SO 2 concentration due industrial sources, behaviour fumigating plumes power plant stacks. National Centers Environmental Prediction analyses are used input synoptic model, multi-level nesting is applied, run with without assimilation surface wind measurements. results show that TAPM simulates onset sea breezes, their magnitude decay time, reasonably accurately. As regards plume footprint, performs well specialised regulatory driven by observed meteorology Kwinana. expected, gives better predictions when assimilated, but also good. Comparison hourly-averaged dispersion moments (i.e., mean height, standard deviations skewness values), obtained using limited number lidar scans before after fumigation, demonstrates capable realistically simulating fumigation characteristics (e.g., negative vertical skewness) influence direction shear positive lateral skewness).
