Possible Urban Effects on Maximum Daily Rainfall at Paris, St. Louis and Chicago
(American Meteorological Society, 1976)The seasonal maximum daily rainfall values for the 1871?1970 period at these three large cities in different climates were studied to discern trends. Upward trends of 19?38% were found in the warm season values at all ... -
Comparison of Radiosonde and Acoustic Echo Sounder Measurements of Atmospheric Thermal Strata
(American Meteorological Society, 1976)The thermal structure of the atmosphere is observed through simultaneous use of the acoustic echo sounder and standard radiosonde. Radiosonde temperature data and graphic recordings from the acoustic sounder are compared ... -
Variance Estimates in Seasonal Climate Forecasting and Related Food Reserve Requirements
(American Meteorological Society, 1976)A general assessment of the potential reduction in variance of predicted climatological statistics was made on the supposition that long-term seasonal-to-annual climatic averages are causally predictable. The residual ... -
Comments on “Estimation of Long-Term Concentrations using a ‘Universal’ Wind Speed Distribution”
(American Meteorological Society, 1976)tract -
Calculations of Doppler Radar Velocity Spectrum Parameters for a Mixture of Rain and Hail
(American Meteorological Society, 1976)The radar reflectivity factors, the reflectivity-weighted mean terminal velocities (VT), and the standard deviations (σv) of the resulting Doppler spectra, were computed for specified size distributions of rain, dry and ... -
Measuring Atmospheric Turbulence with Airborne Hot-Film Anemometers
(American Meteorological Society, 1976)Extensive flight tests during GATE showed hot-film anemometry to be a useful tool for the airborne measurement of atmospheric turbulence in clear air and in subcloud rain, but not within clouds. Root-mean-square noise ... -
Results of a Comprehensive Atmospheric Aerosol-Radiation Experiment in the Southwestern United States. Part II: Radiation Flux Measurements and Theoretical Interpretation
(American Meteorological Society, 1976)The experimental results in Part I are used in the theoretical interpretation of the radiation flux measurements which were taken with an aircraft. The absorption term of the complex refractive index of aerosols is estimated ... -
A Theoretical Investigation of the Effect of Aerosol Pollutants on Shortwave Flux Divergence in the Lower Troposphere
(American Meteorological Society, 1976)This study is aimed at evaluating shortwave effects of aerosol pollutants in the lower troposphere (surface to 2 km). We have solved the radiative transfer equation for a plane-parallel atmosphere of infinite extent in the ... -
Some Observations on the Joss-Waldvogel Rainfall Disdrometer
(American Meteorological Society, 1976)Laboratory experiments showed that the response of the Joss-Waldvogel rainfall disdrometer, a device designed to measure raindrop size from drop impact, was influenced not only by the size and vertical velocity of the drop ... -
The Relation Between Visibility and the Size-Number Distribution of Airborne Soil Particles
(American Meteorological Society, 1976)Simultaneous visibility observations and size-number distribution measurements of airborne soil particles were made during incidents of soil erosion in west Texas. Visibilities were calculated by applying Mie scattering ... -
A Parameterization of Solar Absorption by Nitrogen Dioxide
(American Meteorological Society, 1976)An analytic expression for the specific heating rate due to solar absorption by nitrogen dioxide is derived by approximating the solar insolation and absorption cross section by simple functions of wavelength. The analytic ... -
In-situ Silver Iodide Coated Titanium Dioxide as an Ice Nucleant
(American Meteorological Society, 1976)It has been found possible to prepare a smoke from a conventional thermal AgI generator in which the particles consist of titanium dioxide coated with AgI. The process involves addition of tetra-butyl-ortho-titanate to the ... -
Observations of an Industrial Cumulus
(American Meteorological Society, 1976)Extensive aircraft observations of thermodynamical parameters, updrafts, condensation nuclei and turbulence were obtained of an isolated, non-precipitating, stationary cumulus cloud growing over a refinery complex. These ... -

Sounder Design Considerations in the Selection of Temperature Sensing Channels
(American Meteorological Society, 1976)Simulation studies on the performance of IR sounders under varying conditions of cloud cover and cloud heights are carried out for Nimbus 6. An analytic function is derived for calculating the relative response to cloud ... -
A Theoretical Study of the St. Louis Heat Island: The Wind and Temperature Distribution
(American Meteorological Society, 1976)A three-dimensional primitive equation model was used to study the St. Louis heat island. In this paper, the influence of synoptic wind speed and wind direction on the heat island is presented. With respect to the synoptic ... -
Results of a Comprehensive Atmospheric Aerosol-Radiation Experiment in the Southwestern United States Part I: Size Distribution, Extinction Optical Depth and Vertical Profiles of Aerosols Suspended in the Atmosphere
(American Meteorological Society, 1976)An exploratory field experiment was undertaken to determine the practicality of a method specifically designed to obtain the optical properties of aerosols as they relate to the earth's radiation balance. The method requires ... -
Test of the Principle of Operation of a Wideband Magnetic Direction Finder for Lightning Return Strokes
(American Meteorological Society, 1976)The principle of operation of a wideband crossed-loop magnetic-field direction finder is studied by comparing the bearing determined from the NS and EW magnetic fields at various times up to 155 ?s after return stroke ... -
