    • Electrical and Microphysical Measurements in Warm Cumulus Clouds Before and After Seeding 

      Murty, A. S. Ramachandra; Selvam, A. M.; Vijayakumar, R.; Paul, S. K.; Murty, Bh V. Ramana (American Meteorological Society, 1976)
      Electrical and microphysical measurements were made in warm maritime and inland cumulus clouds, before and after seeding, by repeated aircraft penetrations at a single level, a few hundred meters above cloud base. Such ...

    • A Solar Aureole Radiometer for Atmospheric Aerosol Studies 

      Platt, C. M. R. (American Meteorological Society, 1976)
      A method of minimizing the effects of direct solar scatter in aureole measurements is described. Experimental results for ?clear? and polluted conditions are illustrated. The effects of large particles on the shape of the ...

    • Comparison of Radiation Computations Using Observed and Estimated Precipitable Water 

      Atwater, Marshall A.; Ball, John T. (American Meteorological Society, 1976)
      Hourly values of total solar radiation are computed by two methods at 11 stations in all regions of the United States for a two-year period. In the first method, precipitable water is computed from radiosonde observations ...

    • Determination of the Cirrus Outflow Divergence as Seen by Satellite 

      Fraedrich, K.; Ruprecht, E.; Trunte, U. (American Meteorological Society, 1976)
      Certain methods are tested to estimate the divergence of the outflow anvil of tropical cloud clusters. These methods are based on the change of digitized brightness values given by a sequence of satellite pictures. From ...

    • Multimoment Doppler Display for Severe Storm Identification 

      Burgess, Donald W.; Hennington, Larry D.; Doviak, Richard J.; Ray, Peter S. (American Meteorological Society, 1976)
      A single-Doppler data display has been developed which allows simultaneous presentation of the principal moments of the Doppler spectrum while retaining ease of viewing and interpretation. Display severe storm signatures ...

    • Change in the Transmissivity Parameter with Atmospheric Path Length 

      Williams, John G. (American Meteorological Society, 1976)
      Calculations and measurements show that the transmissivity parameter t is an increasing function of the optical air mass m. An equation for estimating t for several model atmospheres is presented, and the direct beam flux ...

    • Comments on “Discussion of the Elsasser Formulation for Infrared Fluxes” 

      Charlock, T.; Herman, B. M.; Zdunkowski, W. G. (American Meteorological Society, 1976)
      Charlock and Herman (1976, hereafter CH) have criticized the formulation of the radiative flux equation of Zdunkowski et al. (ZBL), 1966. While Zdunkowski (Z) finds their paper very interesting, he does not agree with all ...

    • Eigenvector Analysis for Prediction of Time Series 

      Brier, Glenn W.; Meltesen, Gayle T. (American Meteorological Society, 1976)
      The theorem of singular value decomposition is used to represent a data matrix X as the product of a system with a response R to a forcing function F. Algebraically, R is the matrix of principal components and F the transpose ...

    • Comments on “Simulation of Weatherlike Doppler Spectra and Signals” 

      Thompson, Rory O. R. Y. (American Meteorological Society, 1976)
      tract

    • A Pseudospectral Model for Dispersion of Atmospheric Pollutants 

      Christensen, Ove; Prahm, Lars P. (American Meteorological Society, 1976)
      An Eulerian model, describing the dispersion of pollutants in gases and fluids, is developed. The model is based on numerical integration of the dispersion equation, including the effect of advection, diffusion, sinks and ...

    • Reply 

      Ryan, R. T. (American Meteorological Society, 1976)

    • Wind Sets from SMS Images: An Assessment of Quality for GATE 

      Suchman, David; Martin, David W. (American Meteorological Society, 1976)
      In this study we explore the accuracy, representativeness and reproducibility of tracer winds in the area of the 1974 GARP Atlantic Tropical Experiment (GATE). These winds were generated by tracking clouds in Synchronous ...

    • Numerical Simulation of the Orographically Induced Precipitation Distribution for Use in Hydrologic Analysis 

      Colton, Donald E. (American Meteorological Society, 1976)
      A fine-mesh mesoscale numerical model is used to simulate the orographic precipitation process for the purpose of improving estimates of the spatial distribution of precipitation in mountainous areas. Results from integrations ...

    • A Note on “The Behavior of Large, Low-Surface-Tension Water Drops Falling at Terminal Velocity in Air” 

      Green, A. W. (American Meteorological Society, 1976)
      A heuristic explanation of Ryan's (1976) observations of water drop breakup is given in terms of the Rayleigh-Taylor instability of two superposed fluids. The critical values for drop instability agree with the observations. ...

    • Climatology of Wind Direction Fluctuations at Risø 

      Kristensen, L.; Panofsky, H. A. (American Meteorological Society, 1976)
      Standard deviations of wind direction fluctuations at 76 m at Ris? for the first half year of 1975 have been analyzed as functions of wind speed and temperature lapse rate, either measured near the surface or near the level ...

    • Tropical Cyclone Motion and Surrounding Parameter Relationships 

      George, John E.; Gray, William M. (American Meteorological Society, 1976)
