A comparison of atmospheric transport and dispersion calculations over complex terrain was investigated using a mobile profiling system (MPS) versus standard meteorological balloons. Meteorological and sulfur hexafluoride (SF6) concentration data were collected and used to evaluate the performance of a transport and diffusion model coupled with a mass consistency wind field model. Meteorological data were collected throughout April 1995, and parts of August 1995. Both meteorological and concentration data were measured in December 1995. Once the models were validated, the comparison of performance with different upper‐air data were accomplished. The models used included the SCIPUFF (Second‐order Closure Integrated Puff) transport and diffusion model and the MINERVE mass consistency wind model. Evaluation of the models was focused primarily on their effectiveness as a short‐term (one to four hours) predictive tool. These studies showed how the combination of weather and transport models could be used to help direct emergency response following a hazardous material release. The models were used in tandem to direct the deployment of mobile sensors intended to intercept and measure tracer clouds. The MINERVE model was validated for the specific terrain of interest using April 1995 data. The capability of SCIPUFF driven by realistic three‐dimensional wind fields generated by MINERVE is demonstrated using data collected in December 1995. Copyright © 2000 Royal Meteorological Society

On the effects of topography on wind and the generation of currents in a large multi-basin lake

et al. 2005

View full text Add to dashboard Cite

The wind field over a lake surface is the key element in driving the exchange of momentum and energy at the free surface. It is rarely uniform, having a considerable degree of spatial variability, both on a synoptic and a local scale. Topographic features are one of the most common contributors to this variability. The aerodynamic effects of topography on the windfield, and its influence on the circulation patterns and interbasin exchange rates in a large multi-basin lake are documented. The complex landscape that surrounds this lake is dominated by the presence of a mountain peak rising over 900 m above the lake level. The circulation patterns in those basins of the lake located in the leeward side of the mountain reflect the spatial patterns of the wind field generated by the surrounding topography. The spatial variations in the wind field are shown to significantly alter the residence times of each basin and the exchange rates between basins, isolating one from the other two basins of the lake. The inter-basin exchange rates determined with wind field variability are consistent with annual contaminant loadings estimated for each of the three basins, which suggests a close link between chemical and hydrodynamic behavior.

The atmospheric impact of stack emissions from a power plant (tri-generator and boilers) that will be installed in an urban area in the central Po valley (Northern Italy), characterized by calm wind events, is studied and compared with the impact of the existing plant (conventional boilers). Both the plants are supplied by methane gas. The atmospheric dispersion of NO x emitted is simulated, both in the current and future scenario, by the software package ARIA INDUSTRY. The NO x emission rates are set equal to the regulatory emission limits for existing and future boilers, while the tri-generation system emission rates are set equal to the emission limits certified by the system manufacturer. The simulation periods focus over the 2010 winter season. The simulation estimates the impact of NO x emissions on air quality (vertical concentration profiles and concentration maps at the ground) in the urban area close to the plant. The future power plant impact on air quality results lower than the impact of the existing plant, even if the yearly total mass of pollutants emitted in atmosphere from the new power plant is higher than from the existing plant. The emissions of conventional boilers result the main responsible of the air pollution at the ground in the future scenario.
