      Haugen, D. A.; Kaimal, J. C.; Readings, C. J.; Rayment, R. (American Meteorological Society, 1975)
      An experiment comparing turbulence statistics measured from a tower and from probes attached to the tethering cable of a large balloon is described. The results indicate that some important parameters can be measured with ...

    • Variations of Stratospheric Zonal Winds, 20–65 km, 1961–1971 

      Belmont, A. D.; Dartt, D. G.; Nastrom, G. D. (American Meteorological Society, 1975)
      The observed variability patterns of monthly mean zonal winds over an 11-year period, from 80°N?70°S and from 20?65 km, are explained in terms of component patterns of a long-term mean, quasi-biennial, annual and semi-annual ...

    • The Position Stability of Large Water Drops Suspended in a Vertical Wind Tunnel 

      Woodward, M. C.; Stow, C. D. (American Meteorological Society, 1975)
      The behavior of water drops of diameter in excess of 3 mm suspended in a vertical wind tunnel is described and the vertical-position stability quantitatively and qualitatively assessed. The contribution to vertical instability ...

    • Antarctic Aerosols 

      Hogan, Austin W. (American Meteorological Society, 1975)
      Aerosol number concentrations were measured, using a photoelectric nucleus counter, at three locations in Antarctica. This nucleus counter was of high sensitivity and equipped with a diffusion battery to permit estimation ...

    • An Experimental Study of the Detection of Ice Nuclei on Membrane Filters and Other Substrata 

      Langer, Gerhard; Rodgers, James (American Meteorological Society, 1975)
      An experimental study was made of a membrane filter technique for the detection of ice nuclei in which air of controlled humidity flows across the cooled membrane as opposed to the usual static thermal diffusion procedure. ...

    • Steady-State Solution of the Semi-Empirical Diffusion Equation for Area Sources 

      Lebedeff, S. A.; Hameed, S. (American Meteorological Society, 1975)
      Turbulent transport of material emitted from a surface may be described by the steady-state, two-dimensional, semi-empirical diffusion equation. It is shown that, with wind velocity and eddy diffusivity expressed as power ...

    • Estimating Evaporation and Transpiration from Climatological Observations 

      Morton, F. I. (American Meteorological Society, 1975)
      Evaporation and transpiration are estimated from routine climatological observations using a conceptual model that requires no assumptions concerning the availability of water. The versatility of this unorthodox approach ...

    • Tropical Cyclone Movement Forecasts Based on Observations from Satellites 

      Fett, Robert W.; Brand, Samson (American Meteorological Society, 1975)
      A method to predict 24 h movement of tropical cyclones using consecutive daily satellite views is described. The method is based on the observation that changes in the location of major structural features of the storm are ...

    • An Investigation of the Predictive Ability of Several Evaporation Equations 

      Pierson, F. W.; Jackman, A. P. (American Meteorological Society, 1975)
      A number of integrated flux-gradient type evaporation equations have been tested using very accurate evaporation and meteorological data. The test compared the estimated evaporation with the measured evaporation. Most of ...

    • An Investigation of Extreme Low-Level Wind Shear at Selected Stations in the Conterminous United States 

      Grossman, Robert L.; Beran, Donald W. (American Meteorological Society, 1975)
      The occurrence of extreme low-level wind shear at 10 stations in the conterminous United States is investigated by applying a bivariate frequency-distribution analysis to rawinsonde and pibal data. Data for Denver, Colo., ...

    • Observing Cold-Night Temperatures of Agricultural Landscapes with an Airplane-Mounted Radiation Thermometer 

      Nixon, Paul R.; Hales, Thomas A. (American Meteorological Society, 1975)
      Surface temperatures of agricultural landscapes were measured during three nights of impending freeze with an airplane-mounted precision radiation thermometer (PRT) to determine the suitability of the instrument for this ...

    • Effect of Observation Time on Mean Temperature Estimation 

      Baker, Donald G. (American Meteorological Society, 1975)
      The increased interest and application of heating degree days (HDD) and growing degree days (GDD) prompted this study into the effect of different observation times upon the mean daily temperature. The study was based upon ...
