Tracer Verification of Trajectory Models

摘要: Abstract Perfluorocarbon tracer data collected during the Cross Appalachian Tracer Experiment (CAPTEX '83) are used to determine accuracy of three trajectory models: an isentropic, isobaric, and a dimensional sigma model. The root-mean-square separation between model trajectories derived from surface concentration is evaluate models assess validity isosigma, mean transport vector assumptions. suggest that wind flow corresponding approximately low middle boundary layer most appropriate for simulating pollutants, isentropic isosigma assumptions more realistic than isobaric assumption, results also indicate synoptic type diurnal variation mixing shell within can affect magnitude trajectories...
