RISNumerical Simulations of Airflows and Tracer Transport in the Southwestern United States
Publisher: American Meteorological Society
Abstract: Project MOHAVE (Measurement of Haze and Visual Effects) produced a unique set of tracer data over the southwestern United States. During the summer of 1992, a perfluorocarbon tracer gas was released from the Mohave Power ...
Lagrangian Dispersion Model for Nonneutrally Buoyant Plumes
Publisher: American Meteorological Society
Abstract: A capability to address positive and negative buoyancy was added to the Higher-Order Turbulence Model for Atmospheric Circulation?Random Puff Transport and Diffusion (HOTMAC?RAPTAD) modeling system. The modeling system was ...
The Critical Richardson Number and the Ratio of the Eddy Transport Coefficients Obtained from a Turbulence Closure Model
Publisher: American Meteorological Society
Abstract: A turbulent closure model is analyzed under the condition that the turbulent flow is steady in its ensemble average and both the advection and diffusion terms, i.e., third moments of turbulence, are neglected in the turbulent ...
Prediction of the Nocturnal Surface Inversion Height
Publisher: American Meteorological Society
Abstract: A simple prognostic equation for predicting the development of the nocturnal surface inversion height is constructed from the thermal energy equation. The purpose of the paper is to provide a simple method to estimate the ...
On the Similarity Functions A, B and C of the Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: The similarity functions A, B and C are computed based on the various scales previously proposed for wind, temperature and height in the planetary boundary layer. The vertically averaged geostrophic wind recently proposed ...
A Simulation of the Wangara Atmospheric Boundary Layer Data
Publisher: American Meteorological Society
Abstract: Previously, the authors have studied a hierarchy of turbulent boundary layer models, all based on the same closure assumptions for the triple turbulence moments. The models differ in complexity by virtue of a systematic ...
A Hierarchy of Turbulence Closure Models for Planetary Boundary Layers
Publisher: American Meteorological Society
Abstract: Turbulence models centered on hypotheses by Rotta and Kolmogoroff are complex. In the present paper we consider systematic simplifications based on the observation that parameters governing the degree of anisotropy are ...
Numerical Simulations of a Stratocumulus-Capped Boundary Layer Observed over Land
Publisher: American Meteorological Society
Abstract: Detailed observations of both mean and turbulence fields of an anticyclonic, quasi-steady state, stratocumulus-capped boundary layer obtained with ground-based and balloonborne equipment during the night of 19/20 November ...
Use of the CAPTEX Data for Evaluations of a Long-Range Transport Numerical Model with a Four-Dimensional Data Assimilation Technique
Publisher: American Meteorological Society
Abstract: A ?four-dimensional data assimilation? technique is employed in a time-dependent, three-dimensional mesoscale model to simulate long-range pollutant transport and diffusion in the eastern United States using the 1983 ...
