Hailfall Data from a Fixed Network for the Evaluation of a Hail Modification Experiment
(American Meteorological Society, 1965)Haifall data collected from a fixed network in northeastern Colorado during three seasons (1960?62) included the estimated impact energy, duration of hailfall, most common stone size, maximum stone size, and number of ... -
Cloud Seeding at Medellin, Columbia, During the 1962–64 Dry Seasons
(American Meteorological Society, 1965)Rapid growth in demand, doubling about every 12 years, led in 1961 to stringent rationing of hydroelectric power and potable water in Medellin, Colombia. After a preliminary study had shown that dry season precipitation ... -
A Measure of Skill in Forecasting a Continuous Variable
(American Meteorological Society, 1965)To test the skill of a forecaster the rule for the score S, for the quantitative forecast of Temperature or a similar variable, becomes S = ?ln(1 ? P1P2 ? 1 where P1 is the cumulative climatic frequency of the forecast ... -
A Grid Method for Predicting the Displacement and Central Pressure of East Coast Cyclones
(American Meteorological Society, 1965)A prediction equation used in graphical prognosis is adapted to a grid for predicting the displacement of cyclones near the east coast of North America. The primary displacement, found using the mean 500-mb geostrophic ... -
The Significance of Mountain Lee Waves as Seen from Satellite Pictures
(American Meteorological Society, 1965)TIROS pictures of mountain lee waves produced by airflow over four different mountains are discussed. The wavelengths of the observed cloud patterns are compared to the mean wind in the troposphere as suggested by Corby ... -
Vertical Motion Calculations and Satellite Cloud Observations over the Western and Central United States
(American Meteorological Society, 1965)Vertical motions over the western and central United States during 19?21 August 1961 were computed by several methods. The resulting angles applicable, at 700 mb or 10,000 ft (600 mb for the Joint Numerical Weather Prediction ... -
The Objective Prediction of Clouds and Precipitation Using Vertically Integrated Moisture and Adiabatic Vertical Motions
(American Meteorological Society, 1965)This article describes and illustrates an objective technique of forecasting clouds, precipitation and precipitation amounts. The system is tailored to fit the specific operation of the National Meteorological Center in ... -

A Propellor-Type Vertical Anemometer
(American Meteorological Society, 1964)A vertical anemometer of the propeller type is described. The instrument is sensitive and economical and output is acceptable to most zero-center millivolt recorders. The voltage output reverses in polarity when the direction ... -
A Laser-Fog Disdrometer
(American Meteorological Society, 1964)An instrument is described for determining the size distribution of fog droplets 4 microns in diameter and larger. A film record of the fog droplets is obtained as they pass relatively undisturbed through the collimated ... -
Time Lag in Ice Crystal Nucleation by Silver Iodide
(American Meteorological Society, 1964)Measurements have been made of the time lag which silver iodide particles exhibit in the nucleation of ice crystals at temperatures between ?8C and ?16C. The time tag is approximately exponential, the decay constants being ... -
Statistical Estimates of Computed Water-Vapor Radiative Flux from Clear Skies at an Oceanic Location
(American Meteorological Society, 1964)Based upon four years of complete data spanning 1957 through 1960 at Ship P, ?clear-sky? multiple regression equations were obtained relating computed long-wave flux from water vapor over Ship P to shipboard measurements ... -
Turbulence Statistics at Douglas Point
(American Meteorological Society, 1964)The standard deviations of azimuth and elevation angle have been determined at Douglas Point, Ontario (at a height of 82 ft), and at Paisley, ten miles distant (at a height of 50 ft), on about 500 occasions during the early ... -
Prediction of Environmental Exposures from Sources near the Ground Based on Hanford Experimental Data
(American Meteorological Society, 1964)Values of peak exposure and standard deviations of exposure distributions downwind from a continuous point source are presented for 46 Hanford ground source diffusion experiments. Exposure data are found to order in terms ...
