    • FACE Rainfall Results: Seeding Effect or Natural Variability? 

      Nickerson, E. C. (American Meteorological Society, 1979)
      An examination of hourly rainfall within areas designated small outside (SO) and large outside (LO) reveals that prior to the introduction of a new seeding device (NEI) in 1975, average peninsular rainfall on seed (S) days ...
    • Gill Propeller Anemometer Frequency Response over the Sea 

      Francey, R. J.; Sahashi, K. (American Meteorological Society, 1979)
      A Gill propeller anemometer transfer function of the form 1 + (2πLv/?)P is used to describe the difference in spectra of vertical wind velocity fluctuations over sea as measured by Gill propeller and sonic anemometers. ...
    • Comments on “Frequency Distribution of Wind Speed near the Surface” 

      Mage, David T. (American Meteorological Society, 1979)

    • Sensitivity of a Cloud Microphysical Model to an Urban Environment 

      Ochs, Harry T.; Semonin, Richard G. (American Meteorological Society, 1979)
      Observations showed increased concentrations of cloud condensation nuclei (CCN) in air samples collected over and downwind of St. Louis when compared to upwind samples. Aircraft observations of urban clouds showed corresponding ...

    • Secular Trend in Extreme Rainfalls? 

      Hershfield, David M. (American Meteorological Society, 1979)
      Increasing attention has recently been given to many facets of climate change. This study focuses on a possible trend in extreme rainfalls in the past two decades based on the records of 135 National Weather Service stations ...

    • Nucleation Experiments with Monodisperse NaCl Aerosols 

      Alofs, D. J.; Trueblood, M. B.; White, D. R.; Behr, V. L. (American Meteorological Society, 1979)
      Nucleation experiments with monodisperse NaCl aerosols showed good agreement with the Köhler theory relating the critical super-saturation Sc to the dry size. Aerosols produced by condensing NaCl showed the same Sc as those ...
    • Silver Concentration in Rainwater from Seeded and Nonseeded Florida Cumuli: 1973–1975 Results 

      Wisniewski, Joe; Sax, Robert I. (American Meteorological Society, 1979)
      The main objective of the Florida Area Cumulus Experiments was to seed groups of supercooled tropical cumulus clouds to convert enough water to ice so that sufficient heat could be released to enhance cloud growth and ...
    • Some Legal Implications of Potholes 

      Hannah, Harold W. (American Meteorological Society, 1979)
      This article is based on case law involving suits by highway users against various highway and street authorities. The article was prompted by damage occurring to Illinois highways during the severe winters of 1976?77, ...
    • Large Particles in Supercooled Regions of Northern Canadian Cumulus Clouds 

      Isaac, G. A.; Schemenauer, R. S. (American Meteorological Society, 1979)
      Measurements have been made of the concentration and phase of large particles (>70 ?m) within the supercooled regions of northern Canadian cumulus clouds. During June and July, for the years 1975 and 1976, a total of 58 ...
    • A Numerical Cloud Model for the Support of Laboratory Experimentation 

      Hagen, Donald E. (American Meteorological Society, 1979)
      A numerical cloud model is presented which can describe the evolution of a cloud starting from moist aerosol-laden air through the diffusional growth regime. The model is designed for the direct support of cloud chamber ...
    • Relationship between Hurricane Surface Winds and L-Band Radar Backscatter from the Sea Surface 

      Weissman, David E.; King, David B.; Thompson, Thomas W. (American Meteorological Society, 1979)
      High-altitude, airborne, L-band synthetic aperture radar (SAR) data were collected in Hurricane Gloria on 28 and 30 September 1976. The backscattered power levels (proportional to the surface scattering coefficient) averaged ...
    • Radiometric Measurements of In-Cloud Temperature Fluctuations 

      Albrecht, Bruce A.; Cox, Stephen K.; Schubert, Wayne H. (American Meteorological Society, 1979)
      The feasibility of measuring in-cloud temperature fluctuations with an infrared radiometer is demonstrated. The results obtained from aircraft measurements in a stratocumulus cloud deck indicate that a radiometer may easily ...
    • Lanczos Filtering in One and Two Dimensions 

      Duchon, Claude E. (American Meteorological Society, 1979)
      A Fourier method of filtering digital data called Lanczos filtering is described. Its principal feature is the use of ?sigma factors? which significantly reduce the amplitude of the Gibbs oscillation. A pair of graphs is ...
    • Monitoring Stratospheric Winds with Concorde-Generated Infrasound 

      Donn, William L.; Rind, David (American Meteorological Society, 1979)
      The relatively low frequency of the sonic boom generated by the Concorde SST permits propagation in the form of infrasound to long range with small attenuation. Signal characteristics at long range are a function of ...
    • Total Droplet Concentrations and Average Droplet Sizes from Simultaneous Liquid Water Content and Extinction Measurements 

      King, W. D.; Handsworth, R. J. (American Meteorological Society, 1979)
      It is shown that when liquid water contents are measured with the CSIRO hot-wire element, and cloud transmission measured in the UV with a simple optical system, then the two measurements can be combined to yield total ...
    • Probability Models of Weather Conditions Occupying a Line or an Area 

      Gringorten, Irving I. (American Meteorological Society, 1979)
      Single-station climatic probability of a meteorological condition can be estimated from a set of observations taken at the station. The probability, however, of the same condition prevailing along a line of sight or line ...
