Some Developments in the Use of Empirical Orthogonal Functions for Mapping Meteorological Fields
(American Meteorological Society, 1986)Some current uses of empirical orthogonal functions (EOF) are briefly summarized, together with some relations with spectral and principal component analyses. Considered as a mean square estimation technique of unknown ... -
Simulated and Observed Influence of the Nocturnal Urban Heat Island on the Local Wind Field
(American Meteorological Society, 1986)A three-dimensional primative equation model was used to simulate the low-level wind field, given the urban heat island as the lower temperature boundary condition. The specification of the average heat island bypassed the ... -
Comments on “Surface Temperature Changes Following the Six Major Volcanic Episodes between 1780 and 1980”
(American Meteorological Society, 1986)No abstract available. -
Microphysics of Clouds Initiated from a 1000 MW Dry Heat Source in Comparison with Environmental Clods—A Statistical Study
(American Meteorological Society, 1986)To evaluate potential atmospheric impacts of wate heat released by dry cooling towers, studies have been made of an oil burning system (the ?Météotron?), which emits sensible heat at a rate of ? 1000 MW and large quantities ... -
Overwater Atmospheric Diffusion: Measurements and Parameterization
(American Meteorological Society, 1986)A series of ten atmospheric tracer experiments provided 62 hours of overwater atmospheric dispersion data. Sulfur hexafluoride (SF6) was released as the tracer gas at a height of 13 m from a ship positioned about 7 km off ... -
Analysis of Concentration Fluctuations from Lidar Observations of Atmospheric Plumes
(American Meteorological Society, 1986)A series of nearly instantaneous vertical cross sections of power-plant plume concentrations obtained by both airborne and ground-based lidar systems for the Electric Power Research Institute (EPRI) Plume Model Validation ... -
Angular Distributions of Downward Longwave Radiance and Their Meteorological Applications
(American Meteorological Society, 1986)Measured thermal radiances (? > 3 ?m) from clear and cloudy skies are averaged over azimuth angles to obtain average sky radiances at various zenith angles. The observed variation of sky emissivity with zenith angle can ... -
Attenuation of Microwaves by Spherical Hail
(American Meteorological Society, 1986)Calculations have been made of the radar backscattering and attenuation cross sections of dry and spongy ice spheres. One set of calculations was the cross sections of spheres with diameters exponentially distributed. As ... -
Evaluation of the Accuracy with Which Dry Deposition Can Be Measured with Current Micrometeorological Techniques
(American Meteorological Society, 1986)By reviewing the physics of the processes leading to dry deposition in the atmospheric surface layer, a number of corrections and possible errors in the determination of the dry deposition fluxes are identified. The concept ... -

Exploratory Data Analysis of 1951–82 Summer Rainfall around Nelspruit, Transvaal, and Possible Effects of 1972–81 Cloud Seeding
(American Meteorological Society, 1986)Eastern Transvaal summer rainfall from 1951 to 1982 is examined for possible changes coincident with the operational hail suppression program, which ran from 1972 to 1981. Rough exploratory methods are used initially and ... -
Subsidence in the Nocturnal Boundary Layer
(American Meteorological Society, 1986)Nights with clear skies and strong radiative cooling that favor the formation of statically stable nocturnal boundary layers (NBL) are also those nights most likely to have subsidence, because of the presence of synoptic ... -
An Investigation of the Transition from Multicell to Supercell Storms
(American Meteorological Society, 1986)Nearly 2½ hours of dual-Doppler radar data with high temporal and spatial resolution are used to examine the evolution and morphology of a thunderstorm that evolved from a complex of small cells into a supercell storm. ... -
Downward Longwave Surface Radiation from Sun-Synchronous Satellite Data: Validation of Methodology
(American Meteorological Society, 1986)An extensive study has been carried out to validate a satellite technique for estimating downward longwave radiation at the surface. The technique, mostly developed earlier, uses operational sun-synchronous satellite data ... -
A Structural-Stochastic Model for the Analysis and Synthesis of Cloud Images
(American Meteorological Society, 1986)A structural-stochastic image model is developed for the analysis and synthesis of cloud images. The ability of the model to characterize the visual appearance of cloud fields observed by satellite with a limited number ... -
Radar Hall Profiles in Switzerland
(American Meteorological Society, 1986)Radar reflectivity profiles of 154 hail cells have been investigated. An average profile (the hail profile) has been derived. A global method has been used since the hail profile is designed to be applied to global hail ... -
Microphysical Characteristics of a Well-Developed Weak Echo Region in a High Plains Supercell Thunderstorm
(American Meteorological Society, 1986)Microphysical measurements in and near the weak echo region of a supercell thunderstorm are discussed. The observations were made in southeastern Montana with an armored T-28 aircraft, which has the capability to measure ... -
Raindrop Size Distribution
(American Meteorological Society, 1986)This paper reviews some of the published results relating to raindrop-size distributions and couples this with some of the authors' results in order to show that the mathematical description of the distribution can be ... -
Lidar Measurements of Wind in the Planetary Boundary Layer: The Method, Accuracy and Results from Joint Measurements with Radiosonde and Kytoon
(American Meteorological Society, 1986)During the Central Illinois Rainfall Chemistry Experiment (CIRCE), the University of Wisconsin lidar measured wind and turbulence profiles through the planetary boundary layer for a 32-h period in conjunction with surface ...
