    • Results of Meteorological Rocket Experiments at Thumba 

      Rao, M. S. V. (American Meteorological Society, 1967)
      A series of 23 successful meteorological rocket experiments were conducted at Thumba Equatorial Rocket Launching Station from July 1964 through July 1966. An analysis of the data collected shows the following pattern of ...

    • Real-Time Meteorological System for Firing of Unguided Rockets 

      Duncan, Louis D.; Rachele, Henry (American Meteorological Society, 1967)
      A real-time meteorological system which has been developed by the U.S. Army Electronics Command, Atmospheric Sciences Laboratory at White Sands Missile Range, is described. The system was designed for computation and ...

    • A Laser Radar for Atmospheric Studies 

      Clemesha, B. R.; Kent, G. S.; Wright, R. W. H. (American Meteorological Society, 1967)
      This paper describes equipment designed to observe variations in atmospheric density at heights up to 65 km by measuring the intensity of light back-scattered from a laser beam. The basic theory of the technique is briefly ...

    • The Accuracy of Thermistors in the Measurement of Upper Air Temperatures 

      Thompson, Donald C.; Keily, D. P. (American Meteorological Society, 1967)
      Preliminary results are presented of laboratory studies of the heat balance in rocketsonde semiconductor thermometers. The so-called dissipation constant of rocketsonde thermistors is a marked function of altitude above ...

    • A Stratospheric Air Tracer Experiment Using Zinc Sulfide 

      Droessler, Earl G.; Heffernan, K. J.; Bigg, E. K. (American Meteorological Society, 1967)
      The feasibility of using the fluorescent properties of zinc sulfide powder to study air motions in the vicinity of jet streams was studied by releasing 230 kg of the substance above the subtropical jet in central Australia ...

    • Some Notes on Forecasting of Winds Aloft by Statistical Methods 

      Reed, Jack W. (American Meteorological Society, 1967)
      Winds aloft statistics from Eniwetok were used to derive a linear regression forecast technique that verified satisfactorily in later application. Other studies showed that these principles were applicable throughout the ...

    • Probability Predictions of Geostrophic Winds 

      Gleeson, Thomas A. (American Meteorological Society, 1967)
      A network sampling theory developed previously is used to obtain limiting probabilities of geostrophic wind components predicted at 500 mb in several synoptic cases. Analogous probabilities are calculated for the kinetic ...

    • Hail Incidence in the Tropics 

      Frisby, E. M.; Sansom, H. W. (American Meteorological Society, 1967)
      This paper is a review and compilation of information concerning the incidence and frequency of hail fall in tropical areas. The authors have gathered the data over a period of years from literary sources and by extensive ...

    • Areal Hail Frequency 

      Carte, A. E. (American Meteorological Society, 1967)
      A dense network of hail observers has been established in the Pretoria-Johannesburg area of the Transvaal, South Africa, permitting an investigation of the relationship between hail frequency and observational area. Three ...

    • The Effect of Shock Waves on a Hailstone Model 

      Favreau, Roger F.; Goyer, Guy G. (American Meteorological Society, 1967)
      The effect of explosively generated shock waves on ice cubes has been investigated in the laboratory. Impact tests on cubes previously exposed to shock demonstrate that the action of the latter weakens the cubes, the effect ...

    • A Statistical Investigation of Persistence in the Israeli Artificial Rainfall Stimulation Experiment 

      Gabriel, K. R.; Avichai, Y.; Steinberg, Raya (American Meteorological Society, 1967)
      A number of tests of the data of the Israeli rainfall stimulation experiment have not shown any evidence of persistence of effects of cloud seeding, either from day to day, or within each season, or from season to season.

    • Silver-Iodide Seeding and Precipitation Initiation in Convective Clouds 

      Battan, Louis J. (American Meteorological Society, 1967)
      Convective clouds on seeded and not-seeded days were observed by means of radar and a pair of high quality, ground-based cameras. Stereographic analysis allowed calculation of cloud-top heights, bearing, and distance from ...

    • Summer Shower Distribution Over the Florida Peninsula as Deduced from Digitized Radar Data 

      Frank, Neil L.; Moore, Paul L.; Fisher, George E. (American Meteorological Society, 1967)
      Radar echoes over the Florida peninsula have been recorded manually every 3 hr on a 7.5 by 7.5 mi grid during the past three summers. This note summarizes the echo distribution for the period May through August 1963. The ...

    • Comparison of Estimated and Measured Long-Term I Concentrations from a Continuous Elevated Source 

      Smith, M. E.; Hull, A. P.; Nagle, C. M. (American Meteorological Society, 1967)
      The continuous release of very small, but detectable amounts of 131I from the Brookhaven Graphite Research Reactor has provided an unusual opportunity for verification of dispersion estimates based on meteorological ...

    • A Three-Layer Diffusion Model as Applied to Unstable Atmospheric Conditions 

      Jaffe, S. (American Meteorological Society, 1967)
      A three-layer numerical model, incorporating the ideas of forced, free, and windless convection, is constructed for use in the two-dimensional diffusion equation for steady state conditions. The eddy diffusivity of momentum ...

    • Surface Temperature Inversions in a Canyon 

      Thompson, Aylmer H. (American Meteorological Society, 1967)
