Assimilation of DMSP and TOVS Satellite Soundings in a Mesoscale Model
(American Meteorological Society, 2000)A modeling investigation explores the impacts of the assimilation of satellite-retrieved soundings on forecast error in the Fifth-Generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale ... -
Fuzzy Categorization of Weather Conditions for Thermal Mapping
(American Meteorological Society, 2000)Thermal mapping is a technique that uses a vehicle-mounted infrared radiometer to measure the variation of road surface temperature (RST). Conventionally, the technique is conducted under three qualitatively categorized ... -
Estimation of Surface and Top-of-Atmosphere Shortwave Irradiance in Biomass-Burning Regions during SCAR-B
(American Meteorological Society, 2000)Using in situ measurements of aerosol optical properties and ground-based measurements of aerosol optical thickness (τs) during the Smoke, Clouds and Radiation?Brazil (SCAR-B) experiment, a four-stream broadband radiative ... -
Cloud Particle Phase Determination with the AVHRR
(American Meteorological Society, 2000)An accurate determination of cloud particle phase is required for the retrieval of other cloud properties from satellite and for radiative flux calculations in climate models. The physical principles underlying phase ... -
The Estimation of Hydrometeor Profiles from Wideband Microwave Observations
(American Meteorological Society, 2000)Profiles of the microphysical properties of clouds and rain cells are essential in many areas of atmospheric research and operational meteorology. To enhance the understanding of the nonlinear and underconstrained relationships ... -
Modeling Surface Sensible Heat Flux Using Surface Radiative Temperatures in a Simple Urban Area
(American Meteorological Society, 2000)Sensible heat fluxes over a light industrial area in Vancouver, British Columbia, Canada, are analyzed from observed tower fluxes and modeled using a bulk heat transfer approach. The bulk transfer models are initialized ... -
Alongwind Dispersion—A Simple Similarity Formula Compared with Observations at 11 Field Sites and in One Wind Tunnel
(American Meteorological Society, 2000)Observations of alongwind dispersion of clouds were collected from 11 field sites and from one wind tunnel and were used to test simple similarity relations. Because most of the observations consist of concentration time ... -
Three Methods to Determine Profiles of Reflectivity from Volumetric Radar Data to Correct Precipitation Estimates
(American Meteorological Society, 2000)The vertical variability of radar reflectivity reduces the reliability of precipitation estimation by radar, especially in complex orography. This important source of error can, at least partially, be corrected for, if the ... -
On the Potential Impact of Irrigated Areas in North America on Summer Rainfall Caused by Large-Scale Systems
(American Meteorological Society, 1998)The potential impact of the increase in irrigated areas in North America during the past 100 years on summer rainfall associated with medium- to large-scale precipitation systems is evaluated conceptually and by several ... -
A Semianalytical Solution to a Diffusion–Deposition–Resuspension Model of Local Contamination
(American Meteorological Society, 1998)This note describes a semianalytical solution to a diffusion?deposition?resuspension model. Calculations of the fate of a point contaminant show that the model performs well in representing the individual effects of ... -
Inference of Marine Atmospheric Boundary Layer Moisture and Temperature Structure Using Airborne Lidar and Infrared Radiometer Data
(American Meteorological Society, 1998)A new technique for retrieving near-surface moisture and profiles of mixing ratio and potential temperature through the depth of the marine atmospheric boundary layer (MABL) using airborne lidar and multichannel infrared ... -
The Impact of Secondary Flow Systems on Air Pollution in the Area of São Paulo
(American Meteorological Society, 1998)The area between the Atlantic Ocean and S?o Paulo is highly polluted due to high emission rates at Cubat?o, a city situated 15 km inland at a steep slope. It was expected that secondary circulations would develop caused ... -
Remote Sounding of Multilayer Cirrus Cloud Systems Using AVHRR Data Collected during FIRE-II-IFO
(American Meteorological Society, 1998)Surface observations show that multilayer clouds frequently occur in frontal areas where cirrus clouds overlie boundary layer convective clouds or stratus clouds. In this paper, an algorithm is presented for the retrieval ... -
Spatial and Temporal Distributions of Lightning over Arizona from a Power Utility Perspective
(American Meteorological Society, 1997)This study was designed to determine whether a spatially significant and temporally persistent variation in cloud-to-ground lightning frequency exists across the Salt River Project (SRP) region of central Arizona. ... -
Variability of SO=4, Total Sulfate, NO−3, and Total Nitrate Scavenging Ratios for the Frontal Boundary Study
(American Meteorological Society, 1997)Precipitation and air concentration data collected during a U.S. Department of Energy?sponsored Frontal Boundary Study (FBS) were used to calculate scavenging ratios. The precipitation data were collected on a 100 km ? 100 ... -
Longwave Radiation on Snow-Covered Mountainous Surfaces
(American Meteorological Society, 1997)Longwave radiation in snow-covered alpine environments was investigated based on LOWTRAN7 calculations. The irradiance from the sky and from the surrounding topography were determined separately in order to detect the ... -
Validation of a Long-Range Trajectory Model Using Gas Balloon Tracks from the Gordon Bennett Cup 95

Meteorology and Forest Fires: Conditions for Ignition and Conditions for Development
(American Meteorological Society, 1997)Following the theoretical model proposed in previous papers in which four types of days and their associated fire risk (daily fire risk, DFR) were defined for each size of fire, the authors conclude that the meteorological ... -
