An Observational Study of the Boundary-Layer Winds in the Exit Region of a Mountain Gap
(American Meteorological Society, 1979)An observational study was undertaken at selected sites in and around a mountain gap to understand the downwind increase of winds transiting the gap. Observations indicate that there is a fanning out of surface winds ... -
Monitoring of the Atmospheric Stability above an Urban and Suburban Site Using Sodar and Radon Measurements
(American Meteorological Society, 1979)This study presents a method of obtaining the quantitative intensity of vertical diffusion during periods of atmospheric stability. This method associates the continuous measurement of radon concentration at ground level ... -
Comparison of Ocean and Island Rainfall in the Tropical North Pacific
(American Meteorological Society, 1979)Recent estimates of oceanic rainfall were compared with measured amounts at 35 islands in the central and western North Pacific. A group of stations on small atolls in a region of convective rainfall had amounts that were ... -
The Potential for Remote Sensing of a Tornado Vortex
(American Meteorological Society, 1979)Plasma has a unique characteristic that can be detected remotely. If there is such a plasma at the interior of the tornado's vortex, then there exists a new method of tornado detection. -
Humidity Fluctuations over a Vegetated Surface Measured with a Lyman-Alpha Hygrometer and a Fine-Wire Thermocouple Psychrometer
(American Meteorological Society, 1979)Simultaneous measurements of humidity fluctuations over a crop made with a specially modified Lyman-alpha hygrometer and a fine-wire thermocouple psychrometer are compared. Standard deviations of the two sets of data are ... -
Formation of Sulfate Particles in the Plume of the Four Corners Power Plant
(American Meteorological Society, 1979)On 6 June 1978, the Four Corners coal-fired power plant plume near Farmington, New Mexico, was sampled with an instrumented twin-engine Aero-commander 680E, up to 90 km downwind from the source. Measurements consisted of ... -
The Use of the Weibull Three-Parameter Model for Estimating Mean Wind Power Densities
(American Meteorological Society, 1979)The Weibull three-parameter model is discussed for estimation of mean wind power densities. This probability density function is a generalization of a number of more conventional density functions. Using wind speed ... -
Aerosol Extinction Coefficient Variations with Altitude at 3.75 μm in a Coastal Marine Environment
(American Meteorological Society, 1979)Aerosol size distributions and meteorological parameters measured with altitude in a marine environment off the Southern California coast are presented. Extinction coefficients for a wavelength of 3.75 ?m are calculated ... -
Analytical Initialization for Three-Dimensional Numerical Models
(American Meteorological Society, 1979)A technique for generating analytical initial conditions for three-dimensional numerical models is presented. The technique combines trigonometric and other mathematical functions with meteorological constraints to construct ... -
Wind Velocity and Convergence Measurements at the Boulder Atmospheric Observatory Using Path-Averaged Optical Wind Sensors
(American Meteorological Society, 1979)In a cooperative field study of the planetary boundary layer, three optical wind sensors were placed around a 300 m meteorological tower in a 450 m equilateral triangle 3?4 m above the terrain. It was found that the ... -
Suburban Energy Balance Estimates for Vancouver, B.C., Using the Bowen Ratio-Energy Balance Approach
(American Meteorological Society, 1979)The energy balance of a suburban site in Vancouver, B.C. in late summer is presented. The balance is obtained from direct measurements of net radiation, parameterized heat storage and turbulent fluxes determined according ... -
Spectral Variation of Optical Depth at Tucson, Arizona between August 1975 and December 1977
(American Meteorological Society, 1979)A multi-wavelength solar radiometer has been used to monitor the directly transmitted solar radiation at discrete wavelengths spaced through the visible and near-infrared wavelength regions. The relative irradiance of the ... -
Errors in Hailpad Data Reduction
(American Meteorological Society, 1979)A study of the hailfall parameter estimates determined by 11 persons (readers) measuring the hailstone dents on the same aluminum-covered styrofoam hailpads has shown significant differences among many of the readers. The ... -
A Test of a Lapse Rate/Wind Speed Model for Estimating Heat Island Magnitude in an Urban Airshed
(American Meteorological Society, 1979)In the winter of 1975/76 a helicopter was used to obtain temperature profiles across the city of Calgary. This operation was supported by airborne measurements of wind speed and lapse rate at the edge of the city, upwind. ... -
Carrier Balloon Trajectories in the Stratosphere
(American Meteorological Society, 1979)The need for atmospheric sounding data between the surface and 30 mb for the Global Weather Experiment prompted the development of the Carrier Balloon System. During the development period, 23 constant-level balloon flights ... -
Scavenging of Aerosol Particles by Precipitation
(American Meteorological Society, 1979)Airborne measurements have been made of aerosol particle size distributions (>0.01 ?m) in aged air masses, in the plumes from several coal power plants and a large Kraft paper mill, and in the emissions from a volcano, ... -
Comments on “Run Duration Analysis of Surface Wind Speeds for Wind Energy Applications”
(American Meteorological Society, 1979)No abstract available. -
A Theoretical Study of the St. Louis Heat Island: Comparisons Between Observed Data and Simulation Results on the Urban Heat Island Circulation
(American Meteorological Society, 1979)A three-dimensional primitive model was used to predict the early afternoon wind velocity field over St. Louis, Missouri. Four case studies were then performed where model results at various levels were compared with ... -
The Disposition of Silver Released from Soviet Oblako Rockets in Precipitation during the Hall Suppression Experiment Grossversuch IV. Part I: Measurements of Background and a Preliminary Seeding Test
