A Portable, PC-Based System for Making Optical and Electromagnetic Measurements of Lightning
(American Meteorological Society, 2003)A digital video camcorder, a four-channel analog-to-digital (A/D) converter, and a GPS time/position receiver have been interfaced to a portable personal computer (PC) to provide a mobile data-collection platform for making ... -
Cloud Phase Determination Using Ground-Based AERI Observations at SHEBA
(American Meteorological Society, 2003)A new technique for ascertaining the thermodynamic cloud phase from high-spectral-resolution ground-based infrared measurements made by the Atmospheric Emitted Radiance Interferometer (AERI) is presented. This technique ... -
Relationship between the Monin–Obukhov Stability Parameter and the Bulk Richardson Number at Sea under Unstable Conditions, Derived From a Turbulence-Closure Model
(American Meteorological Society, 2003)Relationships between the Monin?Obukhov stability parameter and the bulk Richardson number are useful for explicit calculation of fluxes through the air?sea interface. The most straightforward method assumes simple ... -
An Evaluation of a Drop Distribution–Based Polarimetric Radar Rainfall Estimator
(American Meteorological Society, 2003)A method for estimating the governing parameters of gamma drop size distributions (DSDs) and associated rainfall rates from polarimetric radar measurements at the S band is examined. The technique uses radar reflectivity ... -

Evaluations of CALPUFF, HPAC, and VLSTRACK with Two Mesoscale Field Datasets
(American Meteorological Society, 2003)Results of evaluations of transport and dispersion models with field data are summarized. The California Puff (CALPUFF), Hazard Prediction and Assessment Capability (HPAC), and Chemical/Biological Agent Vapor, Liquid, and ... -
Detection of Important Atmospheric and Surface Features by Employing Principal Component Image Transformation of GOES Imagery
(American Meteorological Society, 2003)The detection of dust, fire hot spots, and smoke from the Geostationary Operational Environmental Satellite (GOES) is made easier by employing the principal component image (PCI) technique. PCIs are created by an eigenvector ... -
Aircraft-Produced Ice Particles (APIPs): Additional Results and Further Insights
(American Meteorological Society, 2003)This paper presents new results from studies of aircraft-produced ice particles (APIPs) in supercooled fog and clouds. Nine aircraft, including a Beech King Air 200T cloud physics aircraft, a Piper Aztec, a Cessna 421-C, ... -
Modeling of Convective–Stratiform Precipitation Processes: Sensitivity to Partitioning Methods
(American Meteorological Society, 2003)Six different convective?stratiform separation techniques are compared and evaluated using 2D numerical simulations of a tropical and a midlatitude continental squall line. The techniques used include a texture algorithm ... -
Measurement and Analysis of a Multiday Photochemical Smog Episode in the Pearl River Delta of China
(American Meteorological Society, 2003)Recent measurements of a photochemical episode in September of 2001 in the Pearl River delta (PRD) were analyzed to gain insight into the meteorological and chemical processes affecting ozone (O3) concentrations in the ... -
Numerical Simulation of Late Wintertime Local Flows in Kathmandu Valley, Nepal: Implication for Air Pollution Transport
(American Meteorological Society, 2003)Air pollution transport in the Kathmandu valley/basin has been investigated by numerical simulation of local flows and the observation of NO2 and SO2. The observation was performed at 22 sites with passive samplers from ... -
A Dynamic and Spatial Scaling Approach to Advection Forecasting
(American Meteorological Society, 2003)Quantitative nowcasts of rainfall are frequently based on the advection of rain fields observed by weather radar. Spectral Prognosis (S-PROG) is an advection-based nowcasting system that uses the observations that rain ... -
A Relationship Between Skin Thermal Conductivity and Gas Polytropic Index in an Open Atmospheric Balloon
