Implications of Small-Scale Flow Features to Modeling Dispersion over Complex Terrain
(American Meteorological Society, 1996)Small-scale, topographically forced wind systems often have a strong influence on flow over complex terrain. A problem is that these systems are very difficult to measure, because of their limited spatial and temporal ... -
Multiple-Parameter Radar Observations of Isolated Florida Thunderstorms during the Onset of Electrification
(American Meteorological Society, 1996)A prime objective of the Convection and Precipitation/Electrification experiment was to Study the electrification of Florida thunderstorms in greater depth using the National Aeronautics and Space Administration/United ... -
Evidence from Tropical Raindrop Spectra of the Origin of Rain from Stratiform versus Convective Clouds
(American Meteorological Society, 1996)An analysis of temporal variations in gamma parameters of raindrop spectra is presented utilizing surface-based observations from the Tropical Ocean Global Atmosphere Couple Ocean-Atmosphere Experiment. An observed dramatic ... -
A Possible Origin of Linear Depolarization Observed at Vertical Incidence in Rain
(American Meteorological Society, 1996)Recent observations by two different nadir-pointing airborne radars with some polarization capabilities have defected surprisingly large linear depolarization ratios at times in convective tropical rain. This depolarization ... -
Evaluation of a Mesoscale Atmospheric Dispersion Modeling System with Observations from the 1980 Great Plains Mesoscale Tracer Field Experiment. Part I: Datasets and Meteorological Simulations
(American Meteorological Society, 1996)The Colorado State University mesoscale atmospheric dispersion (MAD) numerical modeling system, which consists of a prognostic mesoscale meteorological model coupled to a mesoscale Lagrangian particle dispersion model, has ... -
Stochastic Filtering of Rain Profiles Using Radar, Surface-Referenced Radar, or Combined Radar Radiometer Measurements
(American Meteorological Society, 1996)This paper describes a computationally efficient nearly optimal Bayesian algorithm to estimate rain (and drop size distribution) profiles, given a radar reflectivity profile at a single attenuating wavelength. In addition ... -
Simulation of Surface Fluxes and Boundary Layer Development over the Pine Forest in HAPEX-MOBILHY
(American Meteorological Society, 1996)The interaction of the atmospheric boundary layer with the heterogeneous pine forest in HAPEX-MOBILHY on a scale of order 10 km is studied. A state-of-the-art, coupled atmosphere-soil-vegetation model is used and is run ... -
Coherent Observation Operators for Surface Data Assimilation with Application to Snow Depth
(American Meteorological Society, 1996)A method to derive observation operators for surface data assimilation is presented. It is based on a statistical modeling of the physical processes behavior near the surface. It provides a general framework to design such ... -
Biases Due to Gravity Waves in Wind Profiler Measurements of Winds
(American Meteorological Society, 1996)Radar reflectivity for Bragg scattering is proportional to the atmospheric static stability. In vertically propagating gravity waves the perturbations to the static stability and to the winds occur either in phase or out ... -
Optimal Estimation of Rain-Rate Profiles from Single-Frequency Radar Echoes
(American Meteorological Society, 1996)The significant ambiguities inherent in the determination of a particular vertical rain intensity profile from a given time profile of radar echo powers measured by a downward-looking (spaceborne or airborne) radar at a ... -
Detection of Multilayer Cirrus Cloud Systems Using AVHRR Data: Verification Based on FIRE II IFO Composite Measurements
(American Meteorological Society, 1996)A numerical scheme has been developed to identify multilayer cirrus cloud systems using Advanced Very Higher Resolution Radiometer (AVHRR) data. It is based on the physical properties of the AVHRR channels 1?2 reflectance ... -
Comparison of Modeled to Observed Global Irradiance
(American Meteorological Society, 1996)The accuracy of a spectral, clear-sky model to predict hourly global irradiance was investigated using radiation and meteorological observations collected at the Seattle-Tacoma airport between 1 January 1988 and 31 October ... -
Seasonal Variation in Radiative and Turbulent Exchange at a Deciduous Forest in Central Massachusetts
(American Meteorological Society, 1996)Temperate deciduous forests exhibit dramatic seasonal changes in surface exchange properties following on the seasonal changes in leaf area index. Nearly continuous measurements of turbulent and radiative fluxes above and ... -
