    • OBSERVATIONAL PROBABILITIES AND UNCERTAINTY RELATIONS FOR METEOROLOGY 

      Gleeson, Thomas A. (American Meteorological Society, 1959)
      The probability that an atmospheric feature of a given size will be observed in a region with a network of stations randomly distributed relative to the feature is shown to be a function of the feature and region sizes and ...
    • ON ICE-CRYSTAL PRODUCTION BY AEROSOL PARTICLES 

      Fletcher, N. H. (American Meteorological Society, 1959)
      A general theory of the action of small aerosol particles as ice-crystal nuclei is developed and its predictions compared with experiment. It is found possible to decide under what conditions a given particle will act as ...
    • THE ELECTRIC CHARGE ON CONDENSATE AND WATER DROPLETS 

      Magono, Choji; Takahashi, Tsutomu (American Meteorological Society, 1959)
      It was found that dew produced artificially on a thin wire was electrified negatively when the water temperature of the reservoir for supplying water vapor was lower than about 80C and positively when the temperature was ...
    • AN EXAMINATION OF THE VERTICAL WIND PROFILE IN THE LOWEST LAYERS OF THE ATMOSPHERE 

      Johnson, O. (American Meteorological Society, 1959)
      Wind-profile measurements from ½ to 16 m above ground over prairie grass and over a snow surface at the Suffield Experimental Station and from 2 to 16 m over short grass at O'Neill, Nebraska, have been analysed in order ...
    • RELATION OF LONG-PERIOD CIRCULATION ANOMALIES TO TROPICAL STORM FORMATION AND MOTION 

      Ballenzweig, Emanuel M. (American Meteorological Society, 1959)
      Tropical-cyclone frequency in the entire North Atlantic and in the preferred sites of tropical cyclogenesis in the Atlantic undergo fluctuations which composite charts show to be related to the form and position of the ...
    • THE STRATOSPHERIC WARMING OF JANUARY-FEBRUARY 1957 

      Craig, Richard A.; Hering, Wayne S. (American Meteorological Society, 1959)
      The stratospheric warming of January-February 1957 is discussed with reference to the temperature and circulation changes which occurred. We attempt to present a concise description, rather than an explanation, of the ...
    • THE MECHANICS OF INSTABILITY-LINE FORMATION 

      House, Donald C. (American Meteorological Society, 1959)
      It is proposed that under certain conditions of wind flow that temperature changes due to horizontal advection and vertical motion produce a trend towards the formation within a few hours of a line or narrow band of vertical ...
    • CORRIGENDUM 

      Unknown author (American Meteorological Society, 1959)
      Correction to Volume 15, Issue 3, Article 309.
    • EDDY SIZES AS DETERMINED BY THE TEMPERATURE FLUCTUATIONS AT O'NEILL, NEBRASKA, AUGUST AND SEPTEMBER 1953 

      Longley, Richmond W. (American Meteorological Society, 1959)
      Data obtained at O'Neill, Nebraska, during the summer of 1953, particularly data dealing with temperature fluctuations, have been examined to obtain information on eddy sizes. It was found that under conditions of lapse ...
    • GRAPHICAL PRESENTATION OF ENERGY-BUDGET MEASUREMENTS 

      Lowry, William P. (American Meteorological Society, 1959)
      No Abstract Available.
    • DIFFERENTIAL ADVECTION AS A FACTOR IN CLEAR-AIR TURBULENCE 

      Keitz, Edwin L. (American Meteorological Society, 1959)
      Clear-air turbulence observations made by accelerometer measurements have been correlated with six-hour forecasts of the change in vertical stability. The change in stability has been forecast by computing the six-hour ...
    • MEASUREMENT OF ATMOSPHERIC RADIATION BY A BLACK BALL 

      Moller, Fritz (American Meteorological Society, 1959)
      No Abstract Available.
    • A METEOROLOGICAL TRACER TECHNIQUE USING URANINE DYE 

      Robinson, Elmer; Macleod, J. A.; Lapple, C. E. (American Meteorological Society, 1959)
      A water-soluble fluorescent-dye aerosol has been used successfully as a meteorological tracer. Because of simple instrumental analysis of field samples and great sensitivity, the technique offers large savings in the cost ...
    • STUDY OF MESOSYSTEMS ASSOCIATED WITH STATIONARY RADAR ECHOES 

      Fujita, Tetsuya (American Meteorological Society, 1959)
      Mesosystems associated with stationary radar echoes were analyzed. Five of them occurred on 20 July 1956 over the area of the U. S. Weather Bureau's Severe Local Storms Network, and they grew to 300?400 mi in diameter. ...
    • ATMOSPHERIC CONTAMINANTS AT REMOTE CALIFORNIA COASTAL SITES 

      Holzworth, George C. (American Meteorological Society, 1959)
      The chemical analyses of particulate samples obtained by high-volume air-sampling instruments at remote sites near the California coast are shown to be related to trajectories of the sampled air. In particular, high-chloride ...
    • LAG CORRELATIONS OF UPPER WINDS 

      Charles, B. N. (American Meteorological Society, 1959)
      No Abstract Available.
    • THE CONVERSION OF SODIUM CHLORIDE TO HYDROGEN CHLORIDE IN THE ATMOSPHE 

      Robbins, R. C.; Cadle, R. D.; Eckhardt, D. L. (American Meteorological Society, 1959)
      A reaction route is suggested, based on experimental results, for the conversion of sodium chloride particles to gaseous hydrogen chloride in the atmosphere. The first step is the hydrolysis of nitrogen dioxide (NO2) to ...
    • AN EVALUATION OF 12–HR STATISTICAL FORECASTS OF THE 1000- TO 500-MB THICKNESS 

      Harris, Miles F. (American Meteorological Society, 1959)
      The usefulness of a number of variables as predictors of the 1000-500 mb thickness is explored. These predictors are utilized, in several combinations, to form multiple regression equations from which four series of 12-hour ...
    • THE PENETRATION OF ATMOSPHERIC INVERSIONS BY HOT PLUMES 

      Spurr, G. (American Meteorological Society, 1959)
      Power-station chimneys emit hot gases which may be sufficiently buoyant to penetrate inversions associated with periods of smog. Two notable instances of smog in Great Britain have been examined, applying formulae derived ...
    • METEROROLOGICAL “ANGEL” ECHOES 

      Atlas, David (American Meteorological Society, 1959)
      New observations of a variety of ?angel? echo phenomena were made during 1957. These may be grouped into four types: (1) echoes from thermal columns below cumulus clouds; (2) mantle-shaped echoes associated with the ...
