Evaluation of Advanced Microwave Sounding Unit Tropical-Cyclone Intensity and Size Estimation Algorithms
(American Meteorological Society, 2004)Advanced Microwave Sounding Unit (AMSU) data are used to provide objective estimates of 1-min maximum sustained surface winds, minimum sea level pressure, and the radii of 34-, 50-, and 64-kt (1 kt ≡ 0.5144 m s?1) winds ... -
A Multiple-Case Analysis of Nocturnal Radiation-Fog Development in the Central Valley of California Utilizing the GOES Nighttime Fog Product
(American Meteorological Society, 2004)Radiation fog in the Central Valley of California has received very little attention in terms of climatological research. This study uses the Geostationary Operational Environmental Satellite (GOES) nighttime fog product ... -
A General Approach to Double-Moment Normalization of Drop Size Distributions
(American Meteorological Society, 2004)Normalization of drop size distributions (DSDs) is reexamined here. First, an extension of the scaling normalization that uses one moment of the DSD as a scaling parameter to a more general scaling normalization that uses ... -
Initial Cloud Detection Using the EOF Components of High-Spectral-Resolution Infrared Sounder Data
(American Meteorological Society, 2004)Measured cloud spectral signatures in high-resolution infrared interferometer data have been separated from the clear-air signatures using singular value decomposition. Sets of empirical orthogonal functions (EOFs) have ... -
The Kain–Fritsch Convective Parameterization: An Update
(American Meteorological Society, 2004)Numerous modifications to the Kain?Fritsch convective parameterization have been implemented over the last decade. These modifications are described, and the motivating factors for the changes are discussed. Most changes ... -
Diurnal Cycles of Surface Winds and Temperatures as Simulated by Five Boundary Layer Parameterizations
(American Meteorological Society, 2004)Although most of the planetary boundary layer (PBL) parameterizations have demonstrated the capability to reproduce many meteorological phenomena in the lowest few kilometers, little attention has been paid to the prediction ... -
The Impact of High-Frequency Surface Weather Observations on Short-Term Probabilistic Forecasts of Ceiling and Visibility
(American Meteorological Society, 2004)The skill of an automated statistical forecasting system that uses only hourly (top of the hour) surface observations is compared with a system that utilizes hourly and high-frequency (interhour) surface observations to ... -
A Large-Droplet Mode and Prognostic Number Concentration of Cloud Droplets in the Colorado State University Regional Atmospheric Modeling System (RAMS). Part I: Module Descriptions and Supercell Test Simulations
(American Meteorological Society, 2004)The microphysics module of the version of the Regional Atmospheric Modeling System (RAMS) maintained at Colorado State University has undergone a series of improvements, including the addition of a large-cloud-droplet mode ... -
Local Circulations Developed in the Vicinity of Both Coastal and Inland Urban Areas. Part II: Effects of Urban and Mountain Areas on Moisture Transport
(American Meteorological Society, 2004)The moisture distribution near the ground surface in and around the Japanese cities of Osaka and Kyoto was investigated. From the analysis of observed data, the atmosphere over the suburban areas between coastal Osaka and ... -
A Climatological Measure of Extreme Snowdrift Loading on Building Roofs
(American Meteorological Society, 2004)A physical model of snow transport and deposition is used in combination with historical climatological data to derive a climatological measure of extreme snowdrift loads on building roofs. The snowdrift metric used relies ... -
An Experimental Study of Small-Scale Variability of Radar Reflectivity Using Disdrometer Observations
(American Meteorological Society, 2004)Analysis of data collected by four disdrometers deployed in a 1-km2 area is presented with the intent of quantifying the spatial variability of radar reflectivity at small spatial scales. Spatial variability of radar ... -
Raindrop Size Distribution and Radar Parameters at Cape Verde
(American Meteorological Society, 2004)Precipitation measurement using passive or active microwaves from space- or ground-based radar involves hypotheses about the raindrop size distribution (DSD). A universal knowledge of DSD characteristics is needed. A 4-yr ... -
Error Uncertainty Analysis of GPCP Monthly Rainfall Products: A Data-Based Simulation Study
(American Meteorological Society, 2003)This paper focuses on estimating the error uncertainty of the monthly 2.5° ? 2.5° rainfall products of the Global Precipitation Climatology Project (GPCP) using rain gauge observations. Two kinds of GPCP products are ... -
Analysis and Modeling of an Extremely Dense Fog Event in Southern Ontario
(American Meteorological Society, 2004)In this study, a dense fog episode that occurred near Windsor, Ontario, Canada, on 3 September 1999 is investigated. The fog patch, with a spatial scale of several kilometers, reduced visibility on a major highway to a few ... -
