A Numerical Study of Inversion-Layer Breakup and the Effects of Topographic Shading in Idealized Valleys
(American Meteorological Society, 2003)Numerical simulations of inversion-layer breakup in idealized steep valleys are performed using the Advanced Regional Prediction System (ARPS) to investigate the effects of valley width and depth, and topographic shade. ... -
Relationship between Precipitation Rates at the Ground and Aloft—A Modeling Study
(American Meteorological Society, 2003)Two cloud-resolving mesoscale models, the Karlsruhe Atmospheric Mesoscale Model (KAMM) and the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (MM5), were used to ... -

Comments on “The Need to Represent Raindrop Size Spectra as Normalized Gamma Distributions for the Interpretation of Polarization Radar Observations”
(American Meteorological Society, 2003)tract -
Satellite-Based Insights into Precipitation Formation Processes in Continental and Maritime Convective Clouds at Nighttime
(American Meteorological Society, 2003)Nighttime microphysical retrievals can be obtained to a much lesser accuracy than those of the daytime, because of lack of the solar radiation. However, a proper treatment of the brightness temperature difference (BTD) ... -
A Night-Rain Delineation Algorithm for Infrared Satellite Data Based on Microphysical Considerations
(American Meteorological Society, 2003)Information about the microstructure and precipitation potential of cloud revealed by the brightness temperature difference between a thermal IR channel (11 ?m) and a mid-IR channel (3.7 ?m) at nighttime is implemented ... -
The Effect of Lake Temperatures and Emissions on Ozone Exposure in the Western Great Lakes Region
(American Meteorological Society, 2003)A meteorological?chemical model with a 12-km horizontal grid spacing was used to simulate the evolution of ozone over the western Great Lakes region during a 30-day period in the summer of 1999. Lake temperatures in the ... -
Diurnal Variation of Precipitable Water over a Mountainous Area of Sumatra Island
(American Meteorological Society, 2003)Diurnal variations in atmospheric water vapor at Koto Tabang, a mountainous area of Sumatra Island, Indonesia, are studied by analyzing the GPS-derived precipitable water, radiosonde data, and surface meteorological ... -
A Daily Soil Temperature Dataset and Soil Temperature Climatology of the Contiguous United States
(American Meteorological Society, 2003)Although affected by atmospheric circulations, variations in soil temperature result primarily from the radiation and sensible and latent heat exchanges at the surface and heat transfer in the soils of different thermal ... -
Dispersion of a Passive Tracer in Buoyancy- and Shear-Driven Boundary Layers
(American Meteorological Society, 2003)By means of finescale modeling [large-eddy simulation (LES)], the combined effect of thermal and mechanical forcing on the dispersion of a plume in a convective boundary layer is investigated. Dispersion of a passive tracer ... -
Analysis and Prediction of Cirrus-Top Altitude and Ice Water Path in a Mesoscale Area
(American Meteorological Society, 2003)Vertical distributions of clouds have been a focus of many studies, motivated by their importance in radiative transfer processes in climate models. This study examines the horizontal distribution of cirrus clouds by means ... -
Moderation of Cloud Reduction of UV in the Antarctic Due to High Surface Albedo
(American Meteorological Society, 2003)To gauge the impact of clouds on erythemal (sunburn causing) UV irradiances under different surface albedo conditions, UV measurements from two Antarctic sites (McMurdo and South Pole Stations) and a midlatitude site ... -
Modeling the Variability of Sydney Harbor Wind Measurements
(American Meteorological Society, 2003)The time-dependent behavior in the variability of wind measurements is investigated using bivariate generalized autoregressive conditional heteroscedastic models. These models express the current level of short-timescale ... -
Parameterization of Net All-Wave Radiation for Urban Areas
(American Meteorological Society, 2003)A simple scheme to estimate net all-wave radiation (Q*) is evaluated using annual datasets in three urban settings (Chicago, Illinois; Los Angeles, California; and ?ód?, Poland). Results are compared with a regression model ... -
Operational Retrieval of Atmospheric Temperature, Moisture, and Ozone from MODIS Infrared Radiances
(American Meteorological Society, 2003)The algorithm for operational retrieval of atmospheric temperature and moisture distribution, total column ozone, and surface skin temperature from the Moderate Resolution Imaging Spectroradiometer (MODIS) longwave infrared ... -
Multiple Time- and Space-Scale Comparisons of ATLAS Buoy Rain Gauge Measurements with TRMM Satellite Precipitation Measurements
(American Meteorological Society, 2003)This study compares the Tropical Rainfall Measuring Mission (TRMM) microwave imager (TMI) and precipitation radar (PR) rainfall measurements to self-siphoning rain gauge data from 14 open-ocean buoys located in heavy-rain ... -
The Angular Behavior of Emitted Thermal Infrared Radiation (8–12 μm) at a Semiarid Site

Eclipse Anomalies in Atmospheric Motion Vectors Derived from Meteosat Imagery and Their Implications on Data Assimilation
(American Meteorological Society, 2003)This study examines atmospheric motion vectors derived by tracking features in image sequences from Meteosat for anomalies during the second satellite eclipse period of 2001. During eclipse periods (March?April; ... -
Raindrop Size Distributions: Exponential or Gamma—Does the Difference Matter?
(American Meteorological Society, 2003)Gamma functions are widely used in an effort to represent characteristics of observed raindrop size distributions, especially at the small-particle end. However, available instruments do not agree about the character of ... -
