    • THE MEASUREMENT OF WIND VELOCITY BY SONIC MEANS 

      Schotland, R. M. (American Meteorological Society, 1955)
      The theory of the measurement of wind velocity by sonic meansis presented. Two methods are discussed for determination of the rectangular components of the wind vector by use of the sonic principle. The response characteristics ...
    • ON THE CHEMICAL COMPOSITION OF FOG AND CLOUD WATER 

      Houghton, Henry G. (American Meteorological Society, 1955)
      The partial chemical analysis of some ninety samples of fog and cloud water is reported. The fog samples were collected at four locations along the northeast coast of North America, and the cloud samples were obtained on ...
    • PRESSURE-CHANGE THEORY AND THE DAILY BAROMETRIC WAVE 

      Harris, Miles F. (American Meteorological Society, 1955)
      It is proposed that both the semi-diurnal and the diurnal components of the daily pressure wave are the result of horizontal divergence associated with the daily temperature variation. A combined theoretical-empirical ...

    • ON THE FORMATION AND STRUCTURE OF DOWNDRAFTS IN CUMULUS CLOUDS 

      Starr Malkus, Joanne (American Meteorological Society, 1955)
      With use of the model of the steady-state entraining cumulus draft, it is possible to describe the formation and structure of the downdraft observed at the down-shear edge of an oceanic trade-cumulus cloud. The observations ...

    • THE DECAY OF ICE-NUCLEATING PROPERTIES OF SILVER IODIDE IN THE ATMOSPHERE 

      Smith, E. J.; Heffernan, K. J.; Seely, B. K. (American Meteorological Society, 1955)
      Finely divided zinc sulfide and freezing nuclei in the form of silver-iodide smoke were released from separate generators at the same time from the same position on the ground. Both were detected simultaneously at distances ...
    • A NOTE ON THE ANNUAL STA,\IDARD DEVIATION OF DAILY PRESSURE 

      Charles, B. N. (American Meteorological Society, 1955)
      No Abstract Available
    • A NOTE ON CERTAIN INTERESTING AGEOSTROPHIC MOTIONS IN A ROTATING HEMISPHERICAL SHELL 

      Fultz, D.; Frenzen, P. (American Meteorological Society, 1955)
      Certain aspects of Long's experiments (and some later extensions) with fluid motions around obstacles in a rotating hemispherical shell are discussed. For westerly currents, Long demonstrated that Rossby-Haurwitz waves ...
    • THE EFFECT OF WIND SHEAR ON FALLING PRECIPITATION 

      Gunn, K. L. S.; Marshall, J. S. (American Meteorological Society, 1955)
      Precipitation particles which fall from a source aloft through a wind shear are sorted as to size, the largest particles reaching the ground closest to the generating source, the smaller particles further from it. If ...
    • CORRIGENDUM 

      Unknown author (American Meteorological Society, 1955)
      Correction to Volume 12, Issue 1, Article 36.
    • ZONAL DISTRIBUTION OF BAROCLINITY FOR THREE PACIFIC STORMS 

      McClain, E. Paul; Danielsen, Edwin F. (American Meteorological Society, 1955)
      The thermal structure of the troposphere and lower stratosphere during the movement eastward of several Pacific troughs is examined primarily from the standpoint of the distribution of baroclinity within a vertical plane ...
    • ON THE GENERATION OF PRESSURE-JUMP LINES BY THE IMPULSIVE ADDITION OF MOMENTUM TO SIMPLE CURRENT SYSTEMS 

      Tepper, Morris (American Meteorological Society, 1955)
      The problem of the impulsive addition of momentum to a simple current system, discussed previously by Rossby and Cahn, is reexamined and the basic equations are solved by a numerical-graphical technique. The equations ...
    • AN EMPIRICAL STUDY OF PLANETARY WAVES BY MEANS OF HARMONIC ANALYSIS 

      Graham, Roderick D. (American Meteorological Society, 1955)
      The first twelve harmonics of the observed flow pattern of the upper-level westerlies for the 31 days of January 1952 have been computed and are presented in tabular form. It is shown that the sum of the first three harmonics ...
    • THE ROLE OF ADSORPTION IN HETEROGENEOUS NUCLEATION, I: ADSORPTION OF WATER VAPOR ON SILVER IODIDE AND LEAD IODIDE 

      Birstsin, Seymour J. (American Meteorological Society, 1955)
      The adsorption of water vapor on silver iodide and lead iodide was measured, to determine whether a relationship exists between the ability of a particle to take up water vapor on its surface and its nucleating ability. ...
    • FURTHER IMPROVEMENTS IN THE ELECTRONIC DEW-POINT HYGROMETER 

      Barrett, Earl W.; Slater, Robert L.; Newton, Kenneth E. (American Meteorological Society, 1955)
      The electronic dew-point hygrometer described by Barrett and Herndon in 1951 has been improved in three distinct areas: the servo-amplifier system, the optical system in the sensing head, and the operating-adjustment system. ...
    • A STUDY OF A CHARACTERISTIC TPYE OF UPPER-LEVEL FRONTOGENESIS 

      Reed, Richard J. (American Meteorological Society, 1955)
      The potential vorticity on isentropic surfaces is used to study a characteristic type of upper-level frontogenesis ? the development of a sloping stable layer marked by strong vertical wind shear and rapid upward decrease ...
    • THE COMPUTATION OF INFRARED TRANSMISSION BY ATMOSPHERIC WATER VAPOR 

      Godson, Warren L. (American Meteorological Society, 1955)
      A basic problem in atmospheric radiation is the computation of flux transmission (hemispheric radiation) for a narrow interval of the water-vapor spectrum. Individual lines are spaced more or less at random and have widely ...
