    • The Influence of Snowcover on the Atmospheric Circulation and Its Role in Climatic Change: An Analysis Based on Results from the NCAR Global Circulation Model 

      Williams, Jill (American Meteorological Society, 1975)
      The NCAR global circulation model has been used with boundary conditions representing those of a glacial period July, except that areas in North America, Europe, Asia and South America, which formerly were glaciated, have ...

    • An APT Signal Simulator 

      Knapp, Warren W.; Sanik, Paul S. (American Meteorological Society, 1975)
      An inexpensive device designed to simulate video signals produced by the scanning radiometer system used on current NOAA series satellites is described. The simulator features independent control of both visible and infrared ...

    • Experimental Results with a Rain Analyzer 

      Sander, Joerg (American Meteorological Society, 1975)
      The rain analyzer is an instrument with which the main part of the raindrop size spectrum can be determined. During measurements of the rain attenuation of millimeter waves, rainfall was recorded both with rain analyzers ...

    • Stationarity of Mesoscale Airflow in Mountainous Terrain 

      Wooldridge, Gene L.; Ellis, Ronan I. (American Meteorological Society, 1975)
      Criteria for stationarity of turbulent atmospheric flow are examined for the mesoscale in a mountain valley in northeastern Utah. Data from four sequences of superpressure balloon flights are used. The study shows that the ...

    • Chlorides in Natural and Artificial Hailstones 

      Prodi, Franco (American Meteorological Society, 1975)
      A membrane filter technique for precisely locating chlorides on any prepared ice surface has been tested on hailstone cross sections. Chloride patterns, different in intensity in the various growth stages of the hailstones, ...

    • A Method of Removing Lamb Waves from Initial Data for Primitive Equation Models 

      Washington, Warren M.; Baumhefner, David P. (American Meteorological Society, 1975)
      A simple method of reducing the amplitude of Lamb waves in primitive equation model forecasts has been proposed and tested. This method makes use of a Boussinesq-type approximation in which the vertical mean mass divergence ...

    • The Dependence of Bare Soil Albedo on Soil Water Content 

      Idso, S. B.; Jackson, R. D.; Reginato, R. J.; Kimball, B. A.; Nakayama, F. S. (American Meteorological Society, 1975)
      Simple albedo measurement may prove useful for sensing surface soil water content and as a research tool in the study of evaporation of water from soil. Intensive concurrent measurements of the albedo and soil water content ...

    • Hail and Raindrop Size Distributions from a Swiss Multicell Storm 

      Federer, B.; Waldvogel, A. (American Meteorological Society, 1975)
      Time-resolved hail and raindrop size distributions measured simultaneously during a multicellular hailstorm are presented. The time variation of the size distributions allowed a detailed analysis of the structure of the ...

    • Charged Droplet Collision Efficiency Measurements 

      Abbott, C. E. (American Meteorological Society, 1975)
      Experimental measurements are presented for collision efficiencies of highly charged droplets. The drop sizes studied range in radius from 10 to 25 ?m and carry charges of the order of 10?4 esu. Measured collision efficiencies ...

    • Condensation in Jets, Industrial Plumes and Cooling Tower Plumes 

      Wigley, T. M. L. (American Meteorological Society, 1975)
      The one-dimensional theory for the condensation of buoyant plumes is extended to include supersaturation as an extra variable. An additional equation describing the dynamics of droplet growth is used to make the system ...

    • Operational Applications of a Pure Acoustic Sounding System 

      Parry, H. Dean; Sanders, Melvin J.; Jensen, Hans P. (American Meteorological Society, 1975)
      A monostatic acoustic sounding system and its capabilities in providing information about the temperature structure of the lower atmosphere are described. By means of the sounder record the meteorologist can 1) detect ...

    • A Study of Eddy Fluxes Over a Forest 

      Hicks, B. B.; Hyson, P.; Moore, C. J. (American Meteorological Society, 1975)
      Eddy correlation instruments mounted above a plantation of Pinus radiato near Mt. Gambier, South Australia, have been operated during two periods of intensive effort, in May and October, 1972. Measurements of the Reynolds ...

    • Deposition of Particles in a Plant Canopy 

      Aylor, Donald E. (American Meteorological Society, 1975)
      Deposition of ragweed pollen released from a point above a corn crop was directly observed on foliage, and the number of particles deposited was related to the concentration of pollen in the air, the wind within the crop, ...

    • Calibration of the Pollak Counter with Monodisperse Aerosols 

      Liu, Benjamin Y. H.; Pui, David Y. H.; Hogan, Austin W.; Rich, Ted A. (American Meteorological Society, 1975)
      The photoelectric condensation nucleus counter of Pollak with convergent light beam has been compared with an electrical aerosol detector using monodisperse aerosols with particle diameters between 0.025 and 0.15 ?m, ...

    • A Portable Aerosol Detector of High Sensitivity 

      Hogan, A.; Winters, W.; Gardner, G. (American Meteorological Society, 1975)
      A portable photoelectric nucleus counter, with similar sensitivity to the Pollak photoelectric nucleus counter with convergent light beam, has been developed and calibrated. This instrument has been incorporated into a ...
