A Numerical Analysis of the Effect of Condensation on Plume Rise
(American Meteorological Society, 1975)This paper presents the results of a numerical solution of the equations of moist plume rise and compares the trajectories of wet and dry cooling tower and scrubbed industrial plumes under a wide range of atmospheric ... -
The Design and Performance of a 6-Cup Anemometer
(American Meteorological Society, 1975)An investigation is made into the design and performance of ?staggered? 6-cup anemometers. It is found that the optimum cup arm radius to cup radius ratio (R/r) for both these and 3-cup anemometers is indeterminate; the ... -
Approximation Formulas for the Equilibrium Size of an Aerosol Particle as a Function of Its Dry Size and Composition and the Ambient Relative Humidity
(American Meteorological Society, 1975)Approximations to the exact equations describing the variation with relative humidity of the equilibrium size of aqueous solution droplets are developed. For relative humidities between 81 and 99.5%, and for droplets formed ... -
Application of Soil Dust Optical Properties in Analytical Models of Climate Change
(American Meteorological Society, 1975)Several analytical models of the radiative effects of aerosol layers on global climate provide the common result that the critical value (?c) of the ratio (?) of aerosol layer absorption to hemispheric backscattering is ... -
Flow Across an Urban Area Determined from Double-Theodolite Pilot Balloon Observations
(American Meteorological Society, 1975)Double-theodolite pilot balloon observations at 6 min intervals at two stations upwind and two stations downwind of Oklahoma City provide new information concerning the influence, at heights up to 700 m, of an isolated ... -
A Numerical Experiment on the Effects of Regional Atmospheric Pollution on Global Climate
(American Meteorological Society, 1975)The 1973 Rand version of the Mintz-Arakawa model of the general circulation of the atmosphere was used to study the consequences of high concentrations of hygroscopic aerosols in a limited geographic region. The experiment ... -
Studies of Atmospheric Diffusion from a Nearshore Oceanic Site
(American Meteorological Society, 1975)A research program is in progress at Brookhaven National Laboratory to determine the nature of atmospheric diffusion from a representative oceanic site, to relate observed diffusion patterns to meteorological and oceanographic ... -
Southern Hemisphere Forecast Experiments with a One-Level Spectral Model
(American Meteorological Society, 1975)A one-level primitive equation spectral model has been initialized with hemispheric 500 mb geopotential height and vorticity fields using the Southern Hemisphere GARP data sets for the period 3?12 November 1969 inclusive. ... -
Thermal Changes Induced by Urbanization and Pollutants
(American Meteorological Society, 1975)A numerical model of the planetary boundary layer, based on the Eulerian conservation equation, is used for two- and three-dimensional simulations of wind, temperature, specific humidity and pollutant concentration within ... -
Selected Cases of Convective Precipitation Caused by the Metropolitan Area of Washington, D.C.
(American Meteorological Society, 1975)The release of isolated summer showers in the Washington D.C. area, as related to the urban heat island, was studied for nine propitious synoptic situations in 1968, 1972 and 1973. Parcel theory, using urban surface ... -
Potential of Precipitation Modification in Moderate to Severe Droughts
(American Meteorological Society, 1975)Assuming that successful precipitation modification could be achieved under atmospheric conditions favorable for the development of natural precipitation, a three-phase study was made to acquire information on the potential ... -
Convenient Beta Distribution Likelihood Techniques for Describing and Comparing Meteorological Data
(American Meteorological Society, 1975)A simple reparameterization of the beta distribution is presented. This reparameterization provides a more intuitive description of the beta distribution than the usual version. As a consequence, easily interpreted beta ... -
Numerical Comparison of Five Mean Frequency Estimators
(American Meteorological Society, 1975)Five techniques of estimating power spectrum mean frequency are examined. Performance is given in terms of estimate bias, accuracy, and noise immunity. Techniques examined are: 1) fast Fourier transform, 2) covariance ... -
Bayesian and Classical Statistical Methods Applied to Randomized Weather Modification Experiments
(American Meteorological Society, 1975)Statistical procedures for analyzing the results of randomized weather modification experiments are presented in a format designed to emphasize their underlying assumptions. A parallel development of Bayesian and classical ... -
Evaluation by Monte Carlo Tests of Effects of Cloud Seeding on Growing Season Rainfall in North Dakota
(American Meteorological Society, 1975)Rainfall data collected at 67 gages in a 2750 mi2 target area during a four-year randomized cloud seeding experiment in North Dakota have been stratified in a variety of ways and subjected to several kinds of statistical ... -

On the Design and Evaluation of Cumulus Modification Experiments
(American Meteorological Society, 1975)Combination of numerical simulation, many simultaneous measurements, and a large assortment of statistical tools, employed at all stages, have been found useful in design and evaluation of modification experiments on cumulus ... -
The Effect of Persistence of AgI on Randomized Weather Modification Experiments
(American Meteorological Society, 1975)The hypothesis was tested that AgI may persist for long periods of time and contaminate control experimental days when these control days immediately follow a seeded day. When the first 6 h periods of all such potentially ... -
On Interpolation and Evaluation of Derivatives from a Finite Number of Equally-Spaced Data Points
(American Meteorological Society, 1975)Analytic fields, with several spectral variance power laws, are prescribed and evaluated at a finite number of equally-spaced points. For a given accuracy of interpolation, an unaliased truncated Fourier series is found ...
