The Oblateness of Large Hailstones
(American Meteorological Society, 1967)Ninety large oblate hailstones have been photographed to display thin sections containing their minor and major axes. The ratios of their minor to major axes have been determined throughout their growth from the shapes of ... -
Insoluble Particles in Hail and Rain
(American Meteorological Society, 1967)Varying concentrations of different sized, solid, water-insoluble particles in rainwater and hailstones collected during thunderstorms indicate the existence of several scavenging mechanisms of micron-size particles. It ... -
A Possible Role of Ice-Forming Nuclei in Rain Formation
(American Meteorological Society, 1967)Population of cloud droplets in a cloud may be decreased under some circumstances by their removal (along with other particles) by an ice crystal growing on an ice-forming nucleus. Further condensation of water vapor should ... -
Survival of Cirrus Crystals in Clear Air
(American Meteorological Society, 1967)During the summer of 1966 from Bemidji, Minn., aircraft collections of cirrus crystals were made with a continuous particle replicator. Actual samples show that cirrus crystal trails with a concentrations of 105?106 m?3 ... -
Visibility and Aerosol Size Frequency Distribution
(American Meteorological Society, 1967)The visual quality of the atmosphere in terms of the meteorological range has become a frequently used working standard in aviation and air pollution. Calculations of the meteorological range based on measured size frequency ... -
Mixing Depths, Wind Speeds and Air Pollution Potential for Selected Locations in the United States
(American Meteorological Society, 1967)Daily estimates of morning and afternoon mixing depths and average wind speeds through the mixing layers were calculated and summarized for seven locations in several climatic regions of the contiguous United States. Mixing ... -
Steadiness of the Wind
(American Meteorological Society, 1967)In many atmospheric diffusion problems, a description of the steadiness of the wind direction is desired. For intervals of approximately an hour the mean wind direction is usually well defined and constant, but for longer ... -
On the Direct Determination of the Turbulent Heat Flux Near the Ground
(American Meteorological Society, 1967)The results of a heat flux comparison experiment carried out at Hay, New South Wales, Australia, during May 1966 using a sonic anemometer thermometer (SAT), Fluxatron and Evapotron are reported. The instruments agree with ... -
Specification of Monthly Frequency of Snow Cover Based on Macroscale Parameters
(American Meteorological Society, 1967)The most likely number of days with snow on the ground during an individual month is expressed empirically as a function of the mean temperature and total precipitation for that month, as well as the presence or absence ... -
The Probability of Clear Lines of Sight Through a Cloudy Atmosphere
(American Meteorological Society, 1967)A statistical model has been developed which predicts the probability of observing a clear line of sight through a cloud scene. The basic model is P(?) = P(0) exp(1 + k2 tan2?)½,where ? is the viewing angle measured ... -
A Note on Probability Forecasts and “Hedging”
(American Meteorological Society, 1967)The consideration of a maxim and a statement, both of which are concerned with ?hedging? on the part of meteorologists who prepare probability forecasts, leads to the identification of a property which all proper scoring ... -
A Numerical Procedure for Computing Fields of Stream Function and Velocity Potential
(American Meteorological Society, 1967)A numerical procedure is described for computing a stream-function field from the vorticity of the horizontal wind field. The method was developed for use in meteorological studies which require analyses based solely on ... -
Weather and Solar Radiation Reception in the Equatorial Trough
(American Meteorological Society, 1967)Canton Island (2°49?S, 171°41?W) was selected to study equatorial trough weather conditions and their effects on incoming solar radiation. The chosen study period, July 1957?June 1958, was quite appropriate since the mean ... -
Development, Distribution and Movement of Cyclones and Anticyclones in the Southern Hemisphere During the IGY
(American Meteorological Society, 1967)Charts showing the seasonal frequency distribution of anticyclones, cyclones and cyclogeneses (centers of cyclogenesis) in the Southern Hemisphere south of 15S during the International Geophysical Year are presented. ... -
