Comparison of Gage and Radar Methods of Convective Rain Measurement
(American Meteorological Society, 1975)Gage and radar methods of convective rain measurement are compared in the context of the continuing multiple cloud seeding experiment of the Experimental Meteorology Laboratory. An optimal system, combining the best features ... -
A Numerical Model of Precipitation from Seeded and Unseeded Cold Orographic Clouds
(American Meteorological Society, 1975)This paper describes a numerical model of ice-phase precipitation from orographic clouds which includes the effects of seeding with artificial ice nuclei. The model describes the events which take place when a layer of ... -
An Explanation for the Unusual Nucleating Ability of Aerosols Produced from the AgI-NH4I-Acetone System
(American Meteorological Society, 1975)The exceptional ice nucleating ability of aersols obtained from combustion of AgI-NH4I-acetone solution is now well known. The high nucleating ability has been determined to come from the existence of a complex compound ... -
Analysis of Radar Observations of a Randomized Cloud Seeding Experiment
(American Meteorological Society, 1975)Magnetic tape records for radar observations of 80 moving one-hour test cases in a three-way randomized (no-seed, salt, silver iodide) cloud seeding experiment have been analyzed in terms of echoing areas and radar-estimated ... -
On the Effect of Natural Rainfall Variability and Measurement Errors in the Detection of Seeding Effect
(American Meteorological Society, 1975)Natural rain variability and measurement errors are obstacles to the determination of the seeding effect in convective cloud seeding experiments. The relative importance of these problems in Florida is evaluated in this ... -
Modeling of Cumulus Initiation in METROMEX
(American Meteorological Society, 1975)A numerical cloud modeling project has been initiated as part of METROMEX. A two-dimensional time-dependent model of a vertical slice of the atmosphere has been applied to investigations of cumulus initiation in the St. ... -
Testing of Cloud Seeding Materials at the Cloud Simulation and Aerosol Laboratory, 1971–1973
(American Meteorological Society, 1975)Developments in instrumentation at the Cloud Simulation and Aerosol Laboratory at Colorado State University since the Second International Workshop on Condensation and Ice Nuclei are outlined. Emphasis is given to improvements ... -
Fog Effects Resulting from Power Plant Cooling Lakes
(American Meteorological Society, 1975)A study was made of the potential effects of the waste heat discharge from cooling lakes associated with large power plants in the Midwest upon the distribution of fog, icing and clouds in their vicinity. Emphasis was ... -
The Nature of Winter Clouds and Precipitation in the Cascade Mountains and their Modification by Artificial Seeding. Part III: Case Studies of the Effects of Seeding
(American Meteorological Society, 1975)Three case studies are described in which detailed airborne and ground observations were made in order to evaluate the effects of artificial seeding from the air on cloud structure and snowfall on the ground in a small ... -
The Nature of Winter Clouds and Precipitation in the Cascade Mountains and their Modification by Artificial Seeding. Part II: Techniques for the Physical Evaluation of Seeding
(American Meteorological Society, 1975)Airborne, ground and radar techniques used for evaluating the effects of artificial seeding on winter clouds and precipitation over the Cascade Mountains are described. The clouds were seeded for 1 or 2 h with silver iodide ... -
Design of a Hall Suppression Project for Illinois
(American Meteorological Society, 1975)A description is given of a broad program to Design and Experiment to Suppress Hail (DESH) in Illinois. This program draws on results acquired during 17 years of extensive hail research in Illinois. There are two principal ... -
The Nature of Winter Clouds and Precipitation in the Cascade Mountains and their Modification by Artificial Seeding. Part I: Natural Conditions
(American Meteorological Society, 1975)This is the first of three papers describing field investigations, carried out from 1969 to 1974, of winter clouds and precipitation in the Cascade Mountains of Washington State, and physical evaluations of their modification ... -
Hail Suppression Data from Western North Dakota, 1969–1972
(American Meteorological Society, 1975)Four seasons of hail data were gathered on a randomized cloud seeding project aimed at reducing hail damage and increasing rainfall in western North Dakota. Hail on seed days was generally less severe than on no-seed days. ... -
Small-Scale Variability of Hail and its Significance for Hail Prevention Experiments
(American Meteorological Society, 1975)Studies of small-scale variability of hailfall parameters are being pursued using fine-scale networks of passive hail sensors of various designs. These studies have revealed the great variability which exists in objective ... -
Formation of Graupel
(American Meteorological Society, 1975)Measurements were made of the sizes and concentrations of graupel and snow crystals occurring in seeded and untreated winter storms of the Sierra Nevada. The amounts of rime on individual snow crystals were also determined. ... -
On the Variability of “Dynamic Seedability” as a Function of Time and Location over South Florida: Part I. Spatial Variability
(American Meteorological Society, 1975)Using the one-dimensional cumulus model developed by Cotton, predictions of the effects of seeding cumulus clouds were performed during the month of July 1973 as a part of the Experimental Meteorology Laboratory FACE 1973 ... -
A Detailed Microphysical Simulation of Hygroscopic Seeding on the Warm Rain Process
(American Meteorological Society, 1975)The Wisner one-dimensional time-dependent model has been modified to allow the condensed water forms to be represented by 52 logarithmically spaced size categories covering a range of just under 2 ?m radius to slightly ... -
Florida Area Cumulus Experiments 1970–1973 Rainfall Results
(American Meteorological Society, 1975)After four summer periods of randomized experimentation with dynamic cumulus seeding in a 1.3 ? 104km2 target area in south Florida, 14 seed and 23 control cases are available, with increased documentation of radar measurement ... -
Weather Modification Decision Making: State Law and Public Response
(American Meteorological Society, 1975)A three-year sociological study has focused on a comparison of public response and decision-making processes with reference to weather modification projects in a number of states. Weather modification is currently subject ... -
Weather Modification and Public Opinion in South Dakota, 1972 and 1973
(American Meteorological Society, 1975)Public response to South Dakota's operational cloud seeding program (SDWMP) has been traced since before its implementation. Data are presented from interviews conducted at the end of each of the program's first two ...
