Comments on “Atmospheric Liquid Water Content Derived from Parameterization of Nimbus 6 Scanning Microwave Spectrometer Data”
(American Meteorological Society, 1979)No abstract available. -
The Structures of Summer Convective Clouds in Eastern Montana. I: Natural Clouds
(American Meteorological Society, 1979)The microstructures and precipitation-producing mechanisms in 93 clouds in the vicinity of Miles City, Montana have been explored through airborne measurements. Small cumulus and cumulus complexes contained high cloud ... -
The Structures of Summer Convective Clouds in Eastern Montana. II: Effects of Artificial Seeding
(American Meteorological Society, 1979)The seeding of clouds in Miles City, Montana with AgI pyrotechnics at cloud tops generally produced large increases in ice particle concentrations, decreases in liquid water contents, and increases in precipitation particles ... -
Ice Nucleus Concentrations Measured During the 1975 Florida Area Cumulus Experiment (FACE)
(American Meteorological Society, 1979)Ice nuclei measurements were made aboard a cloud-base aircraft during the 1975 Florida Area Cumulus Experiment. Two techniques were used to obtain the ice nuclei concentrations; membranes were collected and analyzed using ... -
Note on Spectral Diffusivity Theory
(American Meteorological Society, 1979)The diffusion equation with a wavenumber-dependent diffusivity is derived as an approximation to the statistical theory of plume dispersion from a continuous point source. The travel time explicitly appearing in the ... -

A Model for Calculating Desert Aerosol Turbidity over the Oceans from Geostationary Satellite Data
(American Meteorological Society, 1979)A technique has been developed to infer the optical thickness of Saharan dust from Synchronous Meteorological Satellite (SMS) brightness measurements at visible wavelengths. The scattering model consists of an air layer, ... -
A Comparison of Objective and Subjective Means of Weather Typing: An Example from West Texas
(American Meteorological Society, 1979)An objective weather typing scheme first proposed by Christensen and Bryson (1966) was applied to surface and upper air variables for the period April?September of 1973?76 at Midland, Texas. Principal components analysis ... -
Rain-Related Impacts on Selected Transportation Activities and Utility Services in the Chicago Area
(American Meteorological Society, 1979)An intensive meteorological study of summer precipitation in the Chicago area during 1976?78 furnished detailed data needed to perform a study of the impacts of rain on selected transportation-related activities and on ... -
Lidar Measurement of Wind Velocity Profiles in the Boundary Layer
(American Meteorological Society, 1979)A lidar technique for measuring wind in the atmospheric boundary is presented. Inhomogeneities in ambient aerosol content are used as tracers of the wind. This technique yields both horizontal components of the wind and ... -
On Lateral Dispersion Coefficients as Functions of Averaging Time
(American Meteorological Society, 1979)Plume dispersion coefficients are discussed in terms of single-particle and relative diffusion, and are investigated as functions of averaging time. To demonstrate the effects of averaging time on the relative importance ... -
The Energy Balance Microclimate of a Suburban Lawn
(American Meteorological Society, 1979)A suburban lawn was instrumented in order to study its energy balance components during summer conditions. Results indicate that substantial latent heat fluxes can be experienced with values exceeding net radiation during ... -
Observations of Two Colorado Thunderstorms by Means of a Zenith-Pointing Doppler Radar
(American Meteorological Society, 1979)A description is given of the distributions of radar reflectivity, mean Doppler velocity, vertical air velocity and Doppler-velocity variance in two thunderstorms over eastern Colorado. A zenith-pointing Doppler radar was ... -
Comparison of Results Obtained with the VIDIAZ Spectropluviometer and the Joss-Waldvogel Rainfall Disdrometer in a “Rain of a Thundery Type”
(American Meteorological Society, 1979)In this paper the mean values of the raindrop size distribution n(D), rainfall rate R, liquid water content W and radar reflectivity Z obtained by two different instruments are compared: a spectropluviometer which measures ... -
Refractive Index Structure Parameters: Time-Dependent Calculations Using a Numerical Boundary-Layer Model
(American Meteorological Society, 1979)A second-moment turbulence closure model is used to investigate the make-up of the refractive structure parameter Cn2 for acoustic, optical and microwave radiation. For these different forms of radiation, Wesely (1976) ... -
Comparison of Cloud Liquid Content Measured by Two Independent Ground-Based Systems
(American Meteorological Society, 1979)We report on observations of liquid water in clouds made by two independent ground-based microwave instruments. One system is a dual-frequency (20.6, 31.65 GHz) microwave radiometer designed to measure emission from the ... -
Meteorological and Air Pollution Modeling for an Urban Airport
(American Meteorological Society, 1979)Preliminary results are presented for numerical experiments modeling meteorology, multiple pollutant sources and nonlinear photochemical reactions for the case of an airport in a large urban area with complex terrain. The ... -
Measurements of Lagrangian Atmospheric Dispersion Statistics over Open Water
(American Meteorological Society, 1979)Atmospheric dispersion statistics in the Lagrangian frame have been evaluated over open water by using a double-theodolite system to track neutrally buoyant balloons released a few kilometers off-shore during onshore winds. ... -
Comparison of Aerosol at Four Baseline Atmospheric Monitoring Stations
(American Meteorological Society, 1979)Particles were captured by electrostatic precipitators or impactors at atmospheric monitoring bases in Alaska, Hawaii, Tasmania and Antarctica, and examined by electron microscopy. Particle number and mass distributions ... -
Aerosol Particle Size Distribution (0.1–1.0 μm) during the Chinooks of 1979 over Calgary, Canada
(American Meteorological Society, 1979)During the winter months of 1979, an Active Scattering Aerosol Spectrometer was operated in down-town Calgary to measure the effect of chinooks on the aerosol particle size distribution in the range 0.1?1.0 ?m. An Aerovironment ...
