A New Parameterization Scheme for Shortwave Radiative Properties of Water Clouds
(American Meteorological Society, 1995)A new parameterization scheme for the shortwave radiative properties of water clouds is presented, using versatile cloud drop size distributions ( DSDs). As for single-scattering properties, a new parameterization for cloud ... -
Development and Testing of a Surface Flux and Planetary Boundary Layer Model for Application in Mesoscale Models
(American Meteorological Society, 1995)Although the development of soil, vegetation, and atmosphere interaction models has been driven primarily by the need for accurate simulations of long-term energy and moisture budgets in global climate models, the importance ... -
Lidar-Derived Distribution of Cloud Vertical Location and Extent
(American Meteorological Society, 1995)This paper summarizes the results of a statistical analysis of lidar-determined cloud geometrical properties measured during the 1989 and 1991 campaigns of the Experimental Cloud Lidar Pilot Study. Useful lidar descriptors ... -
Assessment of Seeding Effects in Snowpack Augmentation Programs: Ice Nucleation and Scavenging of Seeding Aerosols
(American Meteorological Society, 1995)Trace chemical analysis techniques have been used in a series of cloud-seeding experiments in the central Sierra Nevada with the ultimate purpose of distinguishing whether the submicron-sized aerosol particles used for ... -
Numerical Simulation of a Rain Shower Affected by Waste Energy Released from a Cooling Tower Complex in a Calm Environment
(American Meteorological Society, 1995)An axisymmetric cloud model is used to investigate the evolution of convective cells and associated rain showers that develop due to the sensible and latent heat released into a calm atmosphere from an industrial cooling ... -
Effect of Topology of Water-Ice Mixture on Radar Backscattering by Hailstones
(American Meteorological Society, 1991)The radar backscattering cross sections of spongy hailstones are considerably influenced by the topological structure of the water-ice mixture. Observational evidence suggests that such an inhomogeneous composite medium ... -
Comparison of Ice-Phase Microphysical Parameterization Schemes Using Numerical Simulations of Tropical Convection
(American Meteorological Society, 1991)A numerical cloud model is used to evaluate the performance of several ice parameterizations. Results from simulations using these schemes are contrasted with each other, with an ice-free control simulation, and with ... -
Microwave Simulations of a Tropical Rainfall System with a Three-Dimensional Cloud Model
(American Meteorological Society, 1991)A three-dimensional cloud model-microwave radiative transfer model combination is used to study the relations among the precipitation and other microphysical characteristics of a tropical oceanic squall line and the upwelling ... -
Comment on “Tropical Cyclone-Upper-Atmospheric Interaction as Inferred from Satellite Total Ozone Observations”
(American Meteorological Society, 1991)No abstract available. -
Information Content of AVHRR Channels 4 and 5 with Respect to the Effective Radius of Cirrus Cloud Particles
(American Meteorological Society, 1991)This paper investigates the important difference in the relationship between brightness temperatures between the 11-?m and the 12-?n AVHRR data and the microphysical properties of the semitransparent cirrus clouds. In the ... -

Accuracy of Satellite Land Surface Reflectance Determination
(American Meteorological Society, 1991)An accuracy budget of the surface reflectance determination from Meteosat geostationary satellite data is performed. Error analysis allows identification of three main problems: calibration uncertainty of the Meteosat ... -
The Effect of Drop-Size Distribution Variability on Radiometric Estimates of Rainfall Rates for Frequencies from 3 to 10 GHz
(American Meteorological Society, 1991)The substantial upwelling microwave radiation emitted by rain, as well as the relative simplicity of radiometers, guarantees their continuing important role in measuring rain from space. However, for frequencies greater ... -
Comparison of Simultaneous Airborne and Radiometric Measurements of Supercooled Liquid Water
(American Meteorological Society, 1991)Simultaneous measurements of supercooled liquid water by an instrumented aircraft and a dual-frequency microwave radiometer were made at Lake Ontario, New York, during wintertime. The geographic location and typical ... -
Sky-Cover Correlation within a Sky Dome
(American Meteorological Society, 1991)A new utility for the use of whole-sky photographs has been developed through an effort to discern the structural pattern of correlations of cloud cover within an observer's sky dome. The photographs were taken from the ... -
The Numerical Simulation of Airflow and Dispersion in Three-Dimensional Atmospheric Recirculation Zones
(American Meteorological Society, 1991)A three-dimensional, nonhydrostatic numerical code using the two-equation turbulence closure was developed to model the atmospheric transport and diffusion of pollutants over buildings and a three-dimensional hill. The ... -

Comment on “Persistence and Recurrence Probabilities of Cloud-Free and Cloudy Lines of Sight through the Atmosphere”
(American Meteorological Society, 1991)Although published some time ago, the subject paper represents a well-known resource for modeling and assessing cloud impacts on land-based and air-based electro-optical systems. The Lund dataset, derived from whole-sky ... -
Dual-Doppler Radar Coverage Area as a Function of Measurement Accuracy and Spatial Resolution
(American Meteorological Society, 1979)The area effectively covered by dual-Doppler radars is presented as a function of spatioal resolution and accuracy of horizontal velocity measurement. Implications of this relationship for the spacing of a dual-Doppler ... -
Comparison of Predicted and Observed Solar Radiation in an Urban Area
(American Meteorological Society, 1977)Measurements of the downward solar radiant flux in the St. Louis, Mo., area are compared with predictionsfrom an approximate solution to the radiative transfer equation. The atmospheric aerosols were assumedto have a power ...
