    • THE ARCTIC STRATOSPHERIC JET STREAM DURING THE WINTER OF 1955–1956 

      Lee, Roy; Godson, Warren L. (American Meteorological Society, 1957)
      The existence of an Arctic stratospheric jet stream in winter, hitherto largely inferred from mean geostrophic wind sections, is considered on the basis of actual winds for the Canadian Arctic area during the winter of ...

    • VARIATIONS IN THE HIGH TROPOSPHERIC MEAN FLOW OVER AUSTRALIA AND NEW ZEALAND 

      Radok, Uwe; Grant, Alison M. (American Meteorological Society, 1957)
      As first step in an investigation of changes in the high-level circulation of the southern hemisphere, more than 18,000 radiosonde flights have been used to construct a three-year series of monthly mean cross-sections for ...

    • AIRBORNE MEASUREMENTS OF ATOMIC DEBRIS 

      Machta, L.; Hamilton, H. L.; Hubert, L. F.; List, R. J.; Nagler, K. M. (American Meteorological Society, 1957)
      The primary purpose of this article is the documentation of radioactivity data collected by airborne equipment during the first of the Nevada atomic tests. While absolute magnitudes of activity are not available, the ...

    • BUDGET OF ANGULAR MOMENTUM AND ENERGY IN TROPICAL CYCLONES 

      Palmén, E.; Riehl, Herbert (American Meteorological Society, 1957)
      The surface stress in tropical storms is computed as a function of the radius, from mean wind data in the troposphere. If only the symmetrical part of the circulation is considered, the stress ranges from 1 dyne per square ...

    • POWER SPECTRUM OF HORIZONTAL WIND SPEED IN THE FREQUENCY RANGE FROM 0.0007 TO 900 CYCLES PER HOUR 

      Van der Hoven, Isaac (American Meteorological Society, 1957)
      A power-spectrum analysis of horizontal wind speed is made over a wide range of frequencies by piecing together various portions of the spectrum. There appear to be two major eddy-energy peaks in the spectrum ; one peak ...

    • A NOTE ON THE STABILITY OF BAROCLINIC WAVES 

      Spar, Jerome (American Meteorological Society, 1957)
      The stability characteristics of waves in a thermotropic atmosphere are computed for several velocity profiles. It is shown that the critical wavelength for any wind shear varies considerably with the shape of the velocity ...

    • RAIN SCAVENGING OF RADIOACTIVE PARTICULATE MATTER FROM THE ATMOSPHERE 

      Greenfield, S. M. (American Meteorological Society, 1957)
      On the basis of Langmuir's theory of collection efficiencies, a model is derived to explain the removal of radioactive particulate matter from the atmosphere by rain. In this connection, Langmuir's collection efficiencies ...

    • UPPER-AIR WIND MEASUREMENTS WITH SMALL ROCKETS 

      aufm Kampe, H. J. (American Meteorological Society, 1956)

    • ATMOSPHERIC TURBULENT DIFFUSION FROM INFINITE LINE SOURCES: AN ELECTRIC ANALOG SOLUTION 

      Karplus, Walter J.; Allder, James R. (American Meteorological Society, 1956)
      The steady-state distribution of particles emitted by an infinite line source in the presence of winds and atmospheric turbulence is determined by means of an electric analog approach. A logarithmic wind profile and a ...

    • CLIMATIC CHANGE AS REVEALED BY THE BLOOMING DATES OF THE CHERRY BLOSSOMS AT KYOTO 

      Arakawa, H. (American Meteorological Society, 1956)
      No Abstract Available

    • A STUDY OF CONVECTIVE PRECIPITATION BASED ON CLOUD AND RADAR OBSERVATIONS 

      Battan, Louis J.; Braham, Roscoe R. (American Meteorological Society, 1956)
      Observations of precipitation and cloud-top height in the central United States and in the Caribbean area, obtained from radar-equipped airplanes, have been analyzed in terms of the fraction of clouds of a given height ...

    • COMMENTS ON "EXTENSION OF THE LAWS OF THERMO-DYNAMICS TO TURBULENT SYSTEMS" 

      Arakawa, H. (American Meteorological Society, 1956)
      No Abstract Available

    • COMPUTATION OF STREAMLINES FROM THE PRESSURE FIELD 

      Bundgaard, Robert C. (American Meteorological Society, 1956)
      Although it is simpler to find the pressure field corresponding to a known wind field, practical considerations nevertheless lead us to seek by approximations the wind fields corresponding to a given pressure field. ...

    • ON THE NATURE AND ORIGIN OF THE SOUTHERN OSCILLATION 

      Shell, Irving I. (American Meteorological Society, 1956)
      A physical explanation is given of the nature and origin of the June?August Southern Oscillation and of its relationships with the contemporary, and following September?November and December?February, air and sea temperatures. ...

    • THE EVAPORATION AND REHYDRATION OF AQUEOUS SOLUTIONS 

      Crider, Walter L.; Milburn, Richard H.; Morton, Stephen D. (American Meteorological Society, 1956)
      An experiment is described in which a quartz-fiber microbalance is used to measure the course of rehydration of NaCl particles at various humidities. A comprehensive theory is presented for the rehydration and evaporation ...

    • THE PLAN PATTERN OF SNOW ECHOES AT THE GENERATING LEVEL 

      Langleben, M. P. (American Meteorological Society, 1956)
      The snow-generating elements associated with most snow storms have been observed in previous radar studies only in vertical section. Constant-altitude upper-level maps, composed from a series of plan-position-indicator ...

    • VORTICITY DISTRIBUTION AND ADVECTION IN THE LOWER AND MIDDLE TROPOSPHERE 

      Landers, Holbrook (American Meteorological Society, 1956)
      The three-dimensional distribution of relative vorticity in the lower 25,000 feet of the atmosphere, and over a three-day period of time, is presented and discussed. Absolute-vorticity centers are advected at seven levels ...

    • FORCED AND FREE AXIALLY-SYMMETRIC CONVECTION PRODUCED BY DIFFERENTIAL HEATING IN A ROTATING FLUID 

      Kuo, H-L. (American Meteorological Society, 1956)
      When heat is applied to the outer portion and removed from the inner portion of a rotating fluid, a forced direct symmetric convection is set up. The intensity of this motion is directly proportional to the rate of heating ...

      Kuo, H-L. (American Meteorological Society, 1956)
      The meridional variation of the sum of the non-adiabatic heating and the eddy transfer of heat, and the vertical variation of the sum of the frictional dissipation and eddy transports of zonal momentum, are shown to act ...
