    • On the Graphical Computation of the Montgomery Streamfunction 

      Barber, David A. (American Meteorological Society, 1973)
      A thermodynamic diagram useful in the graphical computation of the Montgomery streamfunction is developed. Examples of the use of the diagram are shown together with an analysis of error for the graphical technique.

    • VHF Direction Finder for Lightning Location 

      Murty, R. C.; MacClement, W. D. (American Meteorological Society, 1973)
      A VHF direction finder based on the technique originally proposed by Oetzel and Pierce for the detection of sferics from lightning has been field tested. Cianos et al. reported a successful test of the same technique using ...

    • Automatic Cloud Cover Indicator System 

      Werner, Christian (American Meteorological Society, 1973)
      A method for developing and constructing a cloud cover indicator system is described. The method involves pointing an IR radiometer vertically downward to a movable mirror and measuring the reflected sky radiation by ...

    • Characteristics of a Laser System for Atmospheric Absorption and Air Pollution Experiments 

      Kucerovsky, Z.; Brannen, E.; Paulekat, K. C.; Rumbold, D. G. (American Meteorological Society, 1973)
      The design and performance of a double-beam laser transmitter and receiver system is described. The transmitter consists of two cw helium-neon lasers, one working at 0.6328 ?m (used as a guide beam), and the other at 3.392 ...

    • A Method of Measuring Low-Velocity Vertical Flow 

      Abbott, C. E. (American Meteorological Society, 1973)
      A method of measuring very low updraft velocities (<1 m sec?1) in vertical wind tunnels is presented. It consists of observing the collision and coalescence of two equal radii droplets. The fall velocity of the resultant ...

    • Supersaturation Development in a Vertical-Flow Thermal Diffusion Chamber 

      Mahata, P. C.; Alofs, D. J.; Sinnarwalla, A. M. (American Meteorological Society, 1973)
      Analytical expressions are derived for temperature and vapor pressure profiles in a vertical-plate, steady-flow, thermal diffusion chamber designed to count cloud condensation nuclei. The influence of longitudinal diffusion ...

    • Ozone and Water Vapor Injected into the Stratosphere from Two Isolated Thunderstorms 

      Shlanta, A.; Kuhn, P. M. (American Meteorological Society, 1973)
      The local ozone concentration and water vapor overburden were measured from a WB-57F aircraft near thunderstorms that reached or penetrated the tropopause. Two storms were studied extensively: one that penetrated 800 m ...

    • Dropsonde Measurements of Vertical Winds in the Colorado Thunderstorm of 22 July 1972 

      Bushnell, R. H. (American Meteorological Society, 1973)
      In connection with the National Hail Research Experiment vertical winds were measured in a thunderstorm by 10 special dropsondes dropped side-by-side over a distance of 4 km. The measurements, made at the northern edge of ...

    • Analysis of Data from T-28 Aircraft Penetrations of a Colorado Hailstorm 

      Musil, D. J.; Sand, W. R.; Schleusener, R. A. (American Meteorological Society, 1973)
      This paper describes results of two penetrations of a moderate intensity storm made by an armored T-28 aircraft on 22 July 1972 as a participant in the National Hail Research Experiment. The penetrations showed multiple ...

    • Precipitation Characteristics of a Sheared, Moderate Intensity, Supercell-Type Colorado Thunderstorm 

      Phillips, Byron B. (American Meteorological Society, 1973)
      A dense 450-station network of hail and rain gages in 2025 km2 of northeastern Colorado has provided surface precipitation data from a moderate intensity thunderstorm that crossed the network on 22 July 1972. The storm, ...

    • Airflow and Moisture Budget Beneath a Northeast Colorado Hailstorm 

      Foote, G. B.; Fankhauser, J. C. (American Meteorological Society, 1973)
      A case study is presented of a persistent thunderstorm of moderate intensity which occurred in northeast Colorado, and which produced a light hailfall at the ground. The storm was intensively monitored by aircraft, radar, ...

    • A Cloud Model to Parameterize Convection 

      Barker, A. A.; Kininmonth, W. R. (American Meteorological Society, 1973)
      This paper describes a parameterization of convection developed for use with a multi-level primitive equation model of the atmosphere. This parameterization is similar in form to that of Kuo, who postulates that boundary ...

    • The Design and Evaluation of an Airborne Optical Ice Particle Counter 

      Turner, F. M.; Radke, L. F. (American Meteorological Society, 1973)
      An airborne instrument which provides real-time measurements of the concentrations of ice particles in excess of a certain size has been developed. The instrument utilizes a beam of polarized light and the birefringent ...
