Abstract: To better understand the impact of various meteorological and chemical parameters on chemical deposition from winter storms, the chemistry and microphysics of a narrow cold-frontal rainband and its associated stratiform ...

Abstract: Previous studies have shown that a surface cold front often coincides with a heavy band of precipitation commonly designated as a narrow cold-frontal rainband. The maximum rainfall rate within this band can exceed 100?200 ...

Abstract: This study uses large-eddy simulation (LES) to illustrate the flow and turbulence structure and to investigate the mechanism of passive scalar transport in a street canyon. Calculations for a modeled street canyon with ...

Abstract: This study employs a large-eddy simulation technique to investigate the flow, turbulence structure, and pollutant transport in street canyons of building-height-to-street-width (aspect) ratios of 0.5, 1.0, and 2.0 at a ...

Abstract: Comparison of in-cloud sulfate production by a bulk-parameterized cloud model, a modified bulk parameterized model, and an explicit microphysical model for a wide variety of scenarios has been used as the basis for deriving ...

Abstract: A growing number of researchers are planning field campaigns that include both meteorological and chemical measurements to increase the value of the collected data sets.Historically, atmospheric field campaigns typically ...

Abstract: A Lagrangian particle dispersion model (LPDM) is used to study fumigation of pollutants in and above the entrainment zone into a growing convective boundary layer. Probability density functions of particle location with ...

Abstract: The current paradigm of developing and testing new aerosol process modules is haphazard and slow. Aerosol modules are often tested for short simulation periods using limited data so that their overall performance over a ...

Abstract: AbstractRecommendations are presented for in situ and remote sensing instruments and capabilities needed to advance the study of convection and turbulence in the atmosphere. These recommendations emerged from a community ...
