    • INTERRELATIONS OF ARCTIC ICE WITH THE ATMOSPHERE AND THE OCEAN IN THE NORTH ATLANTIC—ARCTIC AND ADJACENT AREAS 

      Schell, Irving I. (American Meteorological Society, 1956)
      It is shown that the mean sea-ice limit in the Greenland and Barents Seas during the period April?August is a substantial measure of both the sea-surface temperature near the Faroes and the east coast of Iceland, and the ...
    • INITIAL ELECTRIFICATION PROCESSES IN THUNDERSTORMS 

      Gunn, Ross (American Meteorological Society, 1956)
      Thunderstorm-electrification processes that develop in clouds which are everywhere above the freezing temperature have been analyzed. Nearly equal numbers of highly electrified positive and negative raindrops are formed ...
    • NOTE ON HEMISPHERIC NUMERICAL INTEGRATION OF THE BAROTROPIC MODEL 

      Blackburn, Jacob F.; Gates, W. Lawrence (American Meteorological Society, 1956)
      The computational procedures employed for the numerical integration of the barotropic model for two-dimensional non-divergent flow on a finite-difference grid covering all longitudes of the northern hemisphere south to ...
    • A CONTINUOUSLY RECORDING WATER-CONTENT METER 

      aufm Kampe, H. J.; Weickmann, H. K.; Kelly, J. J. (American Meteorological Society, 1956)
      A simple airborne instrument is described which continuously measures the liquid-water content in ?warm? and supercooled clouds. It is largely temperature independent and has a half-value time of approximately 0.5 second.
    • PRESSURE-HEIGHT PREDICTABILITY AS A FUNCTION OF THE TYPE AND AMOUNT OF INITIAL DATA 

      White, Robert M. (American Meteorological Society, 1956)
      Multiple regression equations for the 24-hour prediction of the pressure-height distribution are examined for the predictability as a function of the number and type of independent variables entering such equations. ...
    • THE DIURNAL TEMPERATURE WAVE FOR BOUNDED EDDY CONDUCTIVITY 

      Staley, Deane O. (American Meteorological Society, 1956)
      Although the coefficient of eddy conductivity varies considerably with time, observations show that this variation cannot in all cases correctly be considered sinusoidal. Solutions for the diurnal temperature wave with the ...
    • MEASUREMENT OF WINDS AT ELEVATIONS OF 30 TO 80 KILOMETERS BY THE ROCKET-GRENADE EXPERIMENT 

      Weisner, Allan G. (American Meteorological Society, 1956)
      Thirty-two values of wind velocity between 30 and 80 kilometers have been obtained from six Aerobee rocket flights made at night at White Sands Proving Ground, New Mexico (32°N), between July 1950 and November 1951. The ...
    • RAINDROP ELECTRIFICATION BY THE ASSOCIATION OF RANDOMLY CHARGED CLOUD DROPLETS 

      Gunn, Ross (American Meteorological Society, 1955)
      Light ions generated in the atmosphere by cosmic rays and radioactivity normally diffuse onto cloud droplets and establish a nearly symmetrical Gaussian distribution of positively and negatively charged droplets. When the ...
    • WATER-VAPOR CONDENSATION AS A CLOUD-DROPLET CHARGING MECHANISM 

      Goyer, Guy G.; Handler, George S. (American Meteorological Society, 1955)
      No Abstract Available
    • ON THE STRUCTURE OF THE ATMOSPHERIC SURFACE LAYER 

      Businger, J. A. (American Meteorological Society, 1955)
      With Prandtl's theory of the mixing length as the point of beginning, a theory concerning the structure of the atmospheric surface layer is proposed on similar assumptions as were put forward by Lettau. The novel feature ...
    • AN INVESTIGATION OF THE STRUCTURE AND DYNAMICS OF AN INTENSE SURFACE FRONTAL ZONE 

      Sanders, Frederick (American Meteorological Society, 1955)
      Intensive analysis of a pronounced surface frontal zone indicates that the associated horizontal temperature gradient, horizontal wind shear and horizontal divergence are most extreme near the ground and become much more ...
    • QUANTITATIVE DETERMINATION OF LONG WAVES AND THEIR TIME VARIATIONS 

      Wolff, Paul M. (American Meteorological Society, 1955)
      A method of space averaging is presented for separating long and short waves in the 500-mb geostrophic flow. The long-wave features are further identified as perturbations. Some of the forecasting characteristics noted in ...
    • THE COMPUTATION OF INFRARED TRANSMISSION BY ATMOSPHERIC WATER VAPOR, PART II 

      Godson, W. L. (American Meteorological Society, 1955)
      The calculation of transmission for a model spectrum requires the adoption of a distribution function for line intensity. In the case of the infrared water-vapor spectrum (random model), a logarithmic ogive distribution ...
    • A DEMONSTRATION OF FRONTS AND FRONTAL WAVES IN ATMOSPHERIC MODELS 

      Faller, Alan J. (American Meteorological Society, 1956)
      The remarkable similarity between the motions in a heated rotating tank of water (dishpan experiments) and the large-scale motions of the atmosphere has raised the question of the similarity of the details of the motion. ...
    • MEASUREMENT OF TEMPERATURES AT ELEVATIONS OF 30 TO 80 KILOMETERS BY THE ROCKET-GRENADE EXPERIMENT 

      Ference, M.; Stroud, W. G.; Walsh, J. R.; Weisner, A. G. (American Meteorological Society, 1956)
      The temperatures in the region of the atmosphere between 30 and 80 kilometers have been determined from measurements of the velocity of sound in nearly vertical propagation. The sources of sound were grenades consecutively ...
    • FURTHER ACOUSTICAL STUDIES OF ATMOSPHERIC WINDS AND TEMPERATURES AT ELEVATIONS OF 30 TO 60 KILOMETERS 

      Kennedy, William B.; Brogan, Lee; Sible, Norman J. (American Meteorological Society, 1955)
      Work under this project was divided into three phases of field operations. The first and second phases of operation were performed in Colorado and were directed toward a study of the annual variations of winds and temperatures ...

    • A STUDY OF SEA-SALT PARTICLES OVER PUERTO RICO 

      Lodge, James P. (American Meteorological Society, 1955)
      A total of eleven flights was made between 12 December 1953 and 16 April 1954 by Air Force B-17's for the purpose of measuring chloride particle concentrations at various altitudes near Puerto Rico. Further, a number of ...
