Computing the Vertical Ozone Distribution from Its Relationship with Total Ozone Amount
(American Meteorological Society, 1969)A method for computing vertical ozone profiles from known total ozone data based on about 8000 vertical ozone profiles taken by the Umkehr method at 30 stations around the world is presented. The computed correlation ... -
Lidar Observations of Airfield Approach Conditions:An Exploratory Study
(American Meteorological Society, 1969)Lidar (laser radar) data obtained at Hamilton AFB, Calif., under conditions of low ceiling and visibility, are analyzed by hand and by electronic computer to explore the operational utility of lidar in determining cloud ... -
The Meteorological Factors Associated with the Precipitation Effects of the Swiss Hail Suppression Project
(American Meteorological Society, 1969)During 1957-63 a randomized experiment to test the efficacy of cloud seeding to suppress hail in the southern Alps was conducted using ground-based silver iodide generators. While the results from the standpoint of hail ... -
Mass Transfer of Rough Hailstone Models in Flows of Various Turbulence Levels
(American Meteorological Society, 1969)The convective mass transfer of smooth and rough sphere test particles over a range of Reynolds numbers between 3 ? 103and 105 was studied by means of an electrochemical method at a Schmidt number of 2170. The experiments ... -
Terminal Velocity of Raindrops Aloft
(American Meteorological Society, 1969)The inadequacy of previous calculations of terminal velocities at other than sea level conditions is discussed. Attention is called to actual measurements of terminal velocities at different air densities, and empirical ... -
AgI-NaI Aerosols as Ice Nuclei
(American Meteorological Society, 1969)The ice-nucleating properties of cloud-seeding aerosols produced by burning a solution af AgI and NaI in acetone have been studied in a laboratory cloud chamber. The ice-forming ability of these mixed aerosols is not ... -
A Pilot Experiment Using Indium as Tracer in a Convective Storm
(American Meteorological Society, 1969)In an effort to determine whether it is feasible to use tracer techniques in the study of circulations and rain scavenging processes in severe convective storms, a pilot experiment using indium as tracer was conducted. A ... -
Detection of Indium as an Atmospheric Tracer by Neutron Activation
(American Meteorological Society, 1969)In a test of the use of indium as a particulate atmospheric tracer, both tagged and untagged rain showers were sampled at ground level in Oklahoma during May 1967. In 29 samples of untagged rain 6±3 nanograms of In per ... -
A Monte Carlo Technique for Designing Cloud Seeding Experiments
(American Meteorological Society, 1969)The desigu of a field experiment in rainfall augmentation requires prior estimates of the duration of the experiment and the density of raingages. A ?Monte Carlo? method was developed to generate synthetic climatological ... -
The Trade Wind Inversion at the Slopes of Mauna Loa, Hawaii
(American Meteorological Society, 1969)Measurments were taken along the east slopes Mauna Loa, Hawaii, to determine whether the normally present trade wind inversion reaches the mountain and whether its properties there are similar to those over the ocean. ... -
A Study of Several Approaches to Computing Surface Insolation over Tropical Oceans
(American Meteorological Society, 1969)The goals of this study were to investigate the potential of various meteorological factors for representing the more variable insolation reductions in the tropical atmosphere, and to develop curves and formulas for those ... -
A Simulation Model for Studying Possible Modification of Surface Temperature
(American Meteorological Society, 1969)A simulation model is presented which hopefully is consistent with known physical and statistical properties of atmospheric events, and consistent with criteria that might be applied in the management of actual experiments ... -
The Role of Initial Uncertainties in Predicion
(American Meteorological Society, 1969)When the initial values, or the parameters, of prognostic equations are not known with certainty, there must also be errors in the solution. The initial conditions may be represented by an ensemble, each member of which ... -
A Numerical Experiment in Predicting Stratus Clouds
(American Meteorological Society, 1969)This study is concerned with the nocturnal development of air mass stratus clouds in south-central Texas and the mechanism which may be responsible for their formation. For this purpose, use has been made of a two-dimensional ... -
