Analysis of Plume Rise Data from Five TVA Steam Plants
(American Meteorological Society, 1985)A large data set containing the measurements of the rise of plumes emitted by five TVA steam plants was examined. Particular attention was paid to the problem of the merging of the plumes emitted by adjacent stacks and to ... -
The Structure of the Ground-Level Heat Island in a Central Business District
(American Meteorological Society, 1985)Ground level temperature variations in Johannesburg were estimated from airborne infrared scanner images. During predawn flights over the city center and vicinity, radiances were observed from a 1-km wide swath under clear ... -
A Multivariate Assessment of Meteorological Influences on Inhalable Particle Source Impacts
(American Meteorological Society, 1985)This paper identifies the sources of fine and coarse inhalable particles at a site in metropolitan Boston and investigates their respective relationships to meteorological conditions. In this work, Principal Component ... -
Radiometric Observations of Supercooled Liquid Water within a Split Front over the Sierra Nevada
(American Meteorological Society, 1985)A storm bearing close structural resemblance to a katafront was observed from the ground with microwave radiometry and a vertically pointing Ka-band radar over the Sierra Nevada of California. The onset and duration of ... -
The Relationship between the Planetary and Surface Net Radiation
(American Meteorological Society, 1985)In this study, an attempt has been made to derive the daily net radiation at the top of the atmosphere using the Geostationary Operational Environmental Satellite (GOES) visible (0.55?0.75 ?m) and IR window (10.5?12.5 ?m) ... -
Analytical Parameterizations of Diffusion: The Convective Boundary Layer
(American Meteorological Society, 1985)A brief review is made of data bases which have been used for developing diffusion parameterizations for the convective boundary layer (CBL). A variety of parameterizations for lateral and vertical dispersion, σy and σz, ... -
Diffusion in the Stably Stratified Atmospheric Boundary Layer
(American Meteorological Society, 1985)The assumptions, techniques and methods of improving Gaussian plume modeling are briefly reviewed. Then the statistical theory for the diffusion of a substance S into a turbulent flow in homogeneous and inhomogeneous flows, ... -
Estimation of Atmospheric Boundary Layer Parameters for Diffusion Applications
(American Meteorological Society, 1985)This paper gives the outline of a ?meteorological preprocessor? for air pollution modeling. It is shown how significantly more information can be extracted from routinely available measurements than the traditional Pasquil ... -
On a New Approach for Instantaneous Rain Area Delineation in the Midlatitudes Using GOES Data
(American Meteorological Society, 1985)Using satellite and weather radar data, a simple clustering analysis has been used in order to differentiate between raining and nonraining clouds. Based on these results, a scheme is proposed for instantaneous rain area ... -
Updating Applied Diffusion Models
(American Meteorological Society, 1985)Most diffusion models currently used in air quality applications are substantially out of date with understanding of turbulence and diffusion in the planetary boundary layer. Under a Cooperative Agreement with the Environmental ... -
Structure of the Planetary Boundary Layer and Implications for its Modeling
(American Meteorological Society, 1985)Through the innovative use of laboratory experiments, numerical simulations, and direct measurements, researchers have greatly extended our knowledge of planetary boundary layer (PBL) structure over the last 15 years. This ... -
Laboratory Experiments on Diffusion:. The Use of Convective Mixed-Layer Scaling
(American Meteorological Society, 1985)A review is presented on laboratory modeling of diffusion downwind of a continuous point source within a boundary layer of well defined height with turbulence driven by buoyant convection. Results of using mixed-layer ... -
Lagrangian Statistical Simulation of Concentration Mean and Fluctuation Fields
(American Meteorological Society, 1985)Lagrangian statistical (Monte Carlo) simulations of the mean and fluctuating concentration fields due to turbulent dispersion are critically reviewed. Attention has been restricted to work in which particle trajectories ... -
Physical Response of Convective Clouds over the Sierra Nevada to Seeding with Dry Ice
(American Meteorological Society, 1985)The effect of seeding convective clouds with dry ice was studied using simultaneous aircraft and radar observations. Clouds that were initially ice-free with supercooled liquid water contents of 0.5 g m?3 when the tops ... -
Doppler Spectra and Estimated Windspeed of a Violent Tornado
(American Meteorological Society, 1985)Presented in this Paper are Doppler spectra of a very large tornado that occurred on 22 May 1981 near Binger, Oklahoma. Tracking of the tornado was accomplished with the help of a novel ?polar spectra display.? Bimodal ... -
Hailstone Size Distributions and Their Relationship to Storm Thermodynamics
(American Meteorological Society, 1985)From ten storms, 184 time-resolved hailstone samples have been collected at the ground in Alberta. For each of the samples collected, hailstone size and concentration were determined and a truncated exponential distribution ... -
The Diurnal Variation of Thunderstorm Activity in the United States
(American Meteorological Society, 1985)Starting times of thunderstorms for 450 stations in the conterminuos United States for a 25-year period were analyzed using harmonic analysis techniques. Diurnal variations were expressed as both the time of maximum storm ... -
A Comparison between Line-Averaged Observation of Cn2 from Scintillation of a CO2 Laser Beam and Time-Averaged in situ Observations
(American Meteorological Society, 1985)The refractive-index structure parameter Cn2 was measured from scintillation of a CO2 laser beam over a 5.9 km path at 40 m height and compared to in situ observations of Cn2 at the optical receiver location. A reasonable ... -
