An Economic Analysis of Hail Suppression
(American Meteorological Society, 1978)The article summarizes an evaluation of the potential economic impacts of two levels of hail suppression technology on crop production in the United States in 1985 and 1995. Analyses are described which consider economic ... -

Drought in the Upper Midwest, 1931–1969
(American Meteorological Society, 1978)Monthly Palmer Drought Index values for the periods 1931?40, 1941?50, 1951?60 and 1961?69 were subjected to eigenvector analysis. Patterns and periods of variable moisture conditions resulted which fit well the patterns ... -
Estimation of Surface Temperature in Remote Pollution Measurement Experiments
(American Meteorological Society, 1978)A simple algorithm has been developed for estimating the actual surface temperature by applying corrections to the effective brightness temperature measured by radiometers mounted on remote sensing platforms. Corrections ... -
Experimental Evaluation of Diffusion Parameters on a Local Scale by Means of No-Lift Balloons
(American Meteorological Society, 1978)Lateral and vertical crosswind standard deviations of Lagrangian tracers at small scale (100?1000 m) have been evaluated during five experimental periods of 15 days at two different Italian sites-a flat country (Po Valley) ... -
Comparison of Reflectivity Measurements by Radar and by Disdrometer
(American Meteorological Society, 1978)Average reflectivities of the rain falling on a ship, measured with a shipborne radar by observing at close range and high elevation angle, are compared with values computed from drop size measurements on the ship. Agreement ... -
Comparison of Stratospheric Trends in Temperature, Ozone and Water Vapor in North Temperate Latitudes
(American Meteorological Society, 1978)Based on smoothed year-average data for the period 1964?76, there has been considerable similarity among the time trends in equatorial tropopause temperature, water vapor amount in the low stratosphere at Washington, DC, ... -
Note on the Aerodynamic Roughness Length for Complex Terrain
(American Meteorological Society, 1978)This note presents field data that demonstrate the application of a logarithmic wind speed profile over complex terrain. For neutral, high wind speed conditions a logarithmic profile with a large z0, on the order of 35 m, ... -
Geochemical Implications of Summer Monsoonal Rainwater Composition over India
(American Meteorological Society, 1978)Rainwater was sampled from ten coastal and inland stations over India during the entire monsoon period of 1975. Major sea salt constituents were analytically determined. Sea salt deposition values based on the sodium content ... -
Atmospheric Turbidity Over Canada
(American Meteorological Society, 1978)A method of evaluating the atmospheric turbidity coefficient from global solar radiation and diffuse sky radiation is formulated. By application of the present method, the turbidity coefficient is evaluated at urban ... -
On the Nature of Vertical Oscillations of Constant Volume Balloons
(American Meteorological Society, 1978)The neutral buoyant oscillation of a spherical balloon floating in the upper troposphere or lower stratosphere is predicted to be between 3 and 4 min for the simplest theoretical case. Variance spectra of balloonborne ... -
Visibility Reduction and Accompanying Aerosol Evolution Downwind of St. Louis
(American Meteorological Society, 1978)Under the auspices of Project METROMEX, studies of visibility deterioration downwind of St. Louis were conducted during August 1976. Estimates of horizontal visibility and aerosol measurements were acquired upwind, over ... -
Parameterization of Sulfate Removal by Precipitation
(American Meteorological Society, 1978)The concentration of sulfate in precipitation is predicted to be directly proportional to the sulfate concentration of the air ingested into the cloud and inversely proportional to cloud water concentration. In addition, ... -
On the Use of Ground Return Targets for Radar Reflectivity Factor Calibration Checks
(American Meteorological Society, 1978)In order to use radar quantitatively, each component of a radar system must be measured or calibrated correctly. This paper reports the results of investigations into the use of ground return signals for checks on the ... -
Correlations between Maximum Rate of Precipitation and Mesoscale Parameters
(American Meteorological Society, 1978)Daily 5, 10 and 30 min maxima of precipitation rate determined from a raingage network and radar were correlated with parcel convective energies, upper air humidity, height of parcel convection and maxima of surface ... -
The Relationship Between Radar Reflectivity Factor and Hail at the Ground for Northeast Colorado Thunderstorms
(American Meteorological Society, 1978)Data from the hailpad network of the National Hail Research Experiment were examined in relation to the equivalent radar reflectivity factors recorded in the lowest level sweeps of the radar beam over the pads during ... -
The Continuous-Impactor-Replicator for Laboratory Cloud Composition Analysis
(American Meteorological Society, 1978)The design and operation of a cloud-sampling device for laboratory applications is described. The cloud particles are collected in a continuous or sequential fashion by impaction, with volatile particle shape and size ... -
Randomized Cloud Seeding in the San Juan Mountains, Colorado
(American Meteorological Society, 1978)A five-year randomized cloud seeding program conducted in the San Juan Mountains of southwestern Colorado by the Bureau of Reclamation was completed in April 1975. The test design included randomization of the seeding by ... -
Doppler Velocity Extraction from Atmospheric Acoustic Echoes Using a Zero-Crossing Technique
(American Meteorological Society, 1978)The scattering of a narrow-band acoustic signal from atmospheric turbulence generates an echo of randomly varying amplitude and frequency. The mean frequency of the power spectrum of this echo is of interest, as it is ...
