Numerical Simulation of a Widely Used Cloud Nucleus Counter
(American Meteorological Society, 1976)The performance of the conventional horizontal plate thermal diffusion chamber as a cloud nucleus counter was studied. Numerical calculations were performed in order to follow the simultaneous drop growth and sedimentation ... -
Comparison of First Radar Echoes in Seeded and Unseeded Convective Clouds in North Dakota
(American Meteorological Society, 1976)First radar echoes on a randomized cloud seeding project in North Dakota appeared closer to cloud base and at higher temperatures on seed days than on no-seed days. The average first echo temperature was near ?11°C on ... -
A Radiative Cooling Model in the Thermal Infrared for Application to Models of the General Circulation
(American Meteorological Society, 1976)The monochromatic ?exchange-between-layers? model of the infrared radiative heat exchanges of an atmosphere (Green, 1967) has been applied to the whole thermal infrared spectrum for model atmospheres as used in the ... -
Application of Least Squares to the Search for Periodicities
(American Meteorological Society, 1976)Recalling that the method of estimation by generalized least squares enables testing of hypotheses on the parameters under estimation, advantage is taken from the fact that the solution given by the classical harmonic ... -
Prediction of Meteorological Factors Related to Beach Erosion at New Jersey and Long Island, N. Y.
(American Meteorological Society, 1976)Prediction of meteorological factors related to storm-caused beach erosion are discussed. Composite sea level pressure maps are presented for beach erosion events that occurred on the New Jersey and Long Island, New York, ... -
On the Response of Superpressure Balloons to Displacements from Equilibrium Density Level
(American Meteorological Society, 1976)An approximate analytical solution of the vertical equation of motion for constant density superpressure balloons is obtained. It is shown how this solution can be used to filter out neutrally buoyant oscillations in balloon ... -

Fortaleza, Ceará, Brazil Rainfall
(American Meteorological Society, 1976)Reanlysis of the 121 years of annual rainfall data at Fortaleza, Ceará, Brazil, given in a note by Markham (1974) does not support the conclusion of periodicities or quasi-periodicities in the data. The hypotheses that the ... -
Weather Modification by Carbon Dust Absorption of Solar Energy
(American Meteorological Society, 1976)Growing global population pressures and predicted future food and energy shortages dictate that man fully explore his potential use of solar energy. This paper investigates the possibility of beneficial weather modification ... -
Height Determination from the Carrier Balloon Dropsonde
(American Meteorological Society, 1976)A procedure has been developed to determine the height of a dropsonde without the use of a pressure sensor. The constant drag characteristic of the dropsonde parachute and the constancy of the tropical atmosphere are used ... -
A Gated, Wideband Magnetic Direction Finder for Lightning Return Strokes
(American Meteorological Society, 1976)A magnetic direction finder has been developed which utilizes only the initial few microseconds of wide-band return stroke waveforms to provide accurate directions to the channel bases of lightning discharges to ground. ... -
Estimates of the Climatic Impact of Aerosols Produced by Space Shuttles, SST's, and other High Flying Aircraft
(American Meteorological Society, 1976)Aircraft and Space Shuttles flying through the stratosphere over the next several decades will add sulfuric acid and aluminum oxide particles, respectively, to this region of the atmosphere. To evaluate the effect of these ... -
Use of a Sailplane to Measure Microphysical Effects of Silver Iodide Seeding in Cumulus Clouds
(American Meteorological Society, 1976)Experiments have been conducted to determine the effects, within cumulus clouds, of seeding with silver iodide; such effects are determined by correlating the presence of ice particles with the presence of silver iodide. ... -
Polarization Diversity Lidar Returns from Virga and Precipitation: Anomalies and the Bright Band Analogy
(American Meteorological Society, 1976)Polarization measurements have been obtained with lidar from ice virga and precipitation. Linear depolarization ratios are characteristically near 0.5 for the ice phase, but can display significantly higher values under ... -
The Collection Efficiencies of Highly Charged Water Drops for Uncharged Cloud Droplets
(American Meteorological Society, 1976)Experiments have been conducted to investigate the collection efficiencies of highly charged drops with radii from 60 to 120 ?m for relatively uncharged droplets of about 20 ?m radius. The measurements indicate that, for ... -
A Numerical Simulation of Warm Fog Dissipation by Electrically Enhanced Coalescence: Part I. An Applied Electric Field
(American Meteorological Society, 1976)It has been suggested that the use of charged particles or electric fields be considered as a technique for dissipating warm fogs. The study presented here attempts to determine the degree of improvement one could expect ... -
A Field Observation of Atmospheric Free Convection
(American Meteorological Society, 1976)Measurements during periods of atmospheric free convection have been made using acoustic echo sounders and conventional wind sensors on a meteorological tower. Comparison of data from the two instrument systems shows good ... -
A Global Average Model of Atmospheric Aerosols for Radiative Transfer Calculations
(American Meteorological Society, 1976)A global average model of the size distribution, chemical composition and optical thickness of stratospheric and tropospheric aerosols is proposed. The uncertainties involved in making the model are emphasized, and some ... -
Evidence for a Reduction in Wind Speed on the Upwind Side of a Tower
(American Meteorological Society, 1976)Double-theodolite pilot balloon observations at the instrumented WKY television tower in Oklahoma City suggest that the anemometers located 3 m from the tower underestimate the mean wind speed by 0.8 m s?1 (?7%) when the ... -
