    • Statistical Forecasts of 24, 48 and 72 h Typhoon and Tropical Storm Intensity Changes 

      Elsberry, Russell L.; Coltrane, Glenn G.; Krueger, Paul L. (American Meteorological Society, 1975)
      A 10 year (1960?69) sample of observations in western North Pacific tropical cyclones over open ocean was used to derive statistical regression equations to forecast the maximum wind speed for 24, 48 and 72 h periods. ...

    • The Life Cycle of Valley Fog. Part I: Micrometeorological Characteristics 

      Pilié, R. J.; Mack, E. J.; Kocmond, W. C.; Rogers, C. W.; Eadie, W. J. (American Meteorological Society, 1975)
      Extensive measurements were made of micrometeorological variables associated with eleven fogs in the Chemung River Valley near Elmira, N.Y. Temperature was measured at five levels on a 17 m tower, dew point at three levels, ...

    • Relating Rainfall Rate to the Slope of Raindrop Size Spectra 

      Merceret, Francis J. (American Meteorological Society, 1975)
      tract

    • The Effect of Solar Radiation Absorption in the Tropical Troposphere 

      Reynolds, David W.; Vonder Haar, Thomas H.; Cox, Stephen K. (American Meteorological Society, 1975)
      Data from an experiment to measure the upward and downward components of solar radiation from aircraft during the Barbados Oceanographic and Meteorological Experiment (BOMEX) have been analyzed in the present study. Two ...

    • Prediction and Measurement of the Accelerated Motion of Water Drops in Air 

      Sartor, J. D.; Abbott, C. E. (American Meteorological Society, 1975)
      The lack of detailed information of the drag forces of cloud droplets during accelerated motion has made it necessary to assume that steady-state drag forces can be used to predict their motion at all times. This assumption ...

    • Effective Cloudiness Derived from Ocean Buoy Data 

      Huang, J. C. K.; Park, J. M. (American Meteorological Society, 1975)
      There is a need in the study of the dynamic aspects of radiation balance at the sea surface for cloud cover information on a finer scale than is presently available, especially for analyses of historic data. Although cloud ...

    • Dual Doppler Radar Coordination Using Nomograms 

      Heymsfield, Gerald M. (American Meteorological Society, 1975)
      A simple nomogram technique to facilitate dual Doppler radar data collection is presented. Equations and nomograms are developed for relating the position of a given target relative to two radars. The results are general, ...

    • An All-Sky Camera for Time-Resolved Lightning Photography 

      Krider, E. Philip (American Meteorological Society, 1975)
      tract

    • The Use of a Vertically Pointing Pulsed Doppler Radar in Cloud Physics and Weather Modification Studies 

      Weiss, Richard R.; Hobbs, Peter V. (American Meteorological Society, 1975)
      It is shown that Doppler radar measurements of the changes with height of the average fallspeeds of solid precipitation particles can be used together with radiosonde data to distinguish between growth of ice particles by ...

    • Broadband Antenna Systems for Lightning Magnetic Fields 

      Krider, E. Philip; Noggle, R. Carl (American Meteorological Society, 1975)
      Broadband magnetic field antenna systems which can resolve submicrosecond structure in lightning waveforms are described. Correlated data on the magnetic and electric fields produced by distant lightning are presented and ...

    • Summer Ice Crystal Precipitation at the South Pole 

      Hogan, Austin W. (American Meteorological Society, 1975)
      Ice crystal precipitation was observed and the crystals replicated, at the South Pole during January and February 1974. The crystals were of columnar form. These columns were hollow or prismatic, and sometimes were in the ...

    • Background Silver Concentrations in Illinois Precipitation and River Water 

      Gatz, Donald F. (American Meteorological Society, 1975)
      This work was undertaken to measure background silver in Illinois precipitation in the absence of any known seeding operations in on near Illinois. The rainfall-weighted mean concentration in samples from several stations ...

    • The Urban Plume as Seen at 80 and 120 km by Five Different Sensors 

      Breeding, R. J.; Haagenson, P. L.; Anderson, J. A.; Lodge, J. P.; Stampfer, J. F. (American Meteorological Society, 1975)
      The records from pollutant sensors abroad two aircraft are compared. The aircraft flew along arcs of either 80 or 120 km radius from the Gateway Arch in St. Louis. One aircraft contained a light-scattering instrument which ...

    • A Variational Technique for Mesoscale Objective Analysis of Air Pollution 

      Heimbach, James A.; Sasaki, Yoshikazu (American Meteorological Society, 1975)
      A technique for the objective analysis of air pollution based on the calculus of variations is described. Rather than find a system of diffusion coefficients which best fit a source inventory and receptor sampling, a series ...

    • Calculated Effects of Aerosols on Sunlight 

      Shotkin, Louis M.; Ludewig, Hans; Thompson, John F. (American Meteorological Society, 1975)
      Solar fluxes have been calculated in a 57-level plane-parallel atmosphere, defined by Elterman's cross sections, using a two-stream approximation to multiple scattering. In this technique, only the integrals of the scattering ...

    • Forecast of Precipitation Probability Based on a Pattern Recognition Algorithm 

      Paegle, Julia N.; Wright, Robert P. (American Meteorological Society, 1975)

    • Frequencies of Short-Period Rainfall Rates Along Lines 

      Sims, Arthur L.; Jones, Douglas M. A. (American Meteorological Society, 1975)
