Mesoscale Meteorological Conditions in Dronning Maud Land, Antarctica, during Summer: A Qualitative Analysis of Forcing Mechanisms
(American Meteorological Society, 2000)Detailed concurrent summer observations of surface meteorological variables, high-resolution boundary layer profiles, and upper-air profiles were carried in the intermediate region between the high plateau and the coast ... -
Freezing Rain Simulations for Fixed, Unheated Conductor Samples
(American Meteorological Society, 2000)The present paper reports on extensive experiments performed on short, fixed, unheated conductor samples in an outdoor freezing rain simulator. Their purpose is to relate the weight of ice (or, alternatively, the equivalent ... -
Estimate of Precipitation from the Dual-Beam Airborne Radars in TOGA COARE. Part II: Precipitation Efficiency in the 9 February 1993 MCS
(American Meteorological Society, 2000)Dual-beam airborne Doppler radars are commonly used in convection experiments for their ability to describe the dynamical structure of weather systems. However, instrumental limitations impose the use of wavelengths such ... -
Moisture Advection Using Relative Humidity
(American Meteorological Society, 2000)This study introduces a moisture advection formulation that contains relative humidity. In the sigma coordinate system, rewriting the mixing ratio conservation equation in terms of relative humidity leads to an equation ... -
Passive Microwave Precipitation Retrievals Using TMI during the Baiu Period of 1998. Part I: Algorithm Description and Validation
(American Meteorological Society, 2000)The Baiu front is a subtropical convergence zone that is formed over east Asia in early summer (hereinafter referred to as the Baiu period). In this study, an overocean precipitation retrieval algorithm is developed to ... -
A New Normalized Difference Cloud Retrieval Technique Applied to Landsat Radiances over the Oklahoma ARM Site
(American Meteorological Society, 2000)The authors propose a new cloud property retrieval technique that accounts for cloud side illumination and shadowing effects present at high solar zenith angles. The technique uses the normalized difference of nadir ... -
The Response of 36- and 89-GHz Microwave Channels to Convective Snow Clouds over Ocean: Observation and Modeling
(American Meteorological Society, 2000)The first study in both observing and modeling radiative properties of snow clouds in the microwave frequencies is described in this paper. Snow clouds over ocean were observed simultaneously using an airborne microwave ... -
Secondary Forecast Models—The ENSO Example
(American Meteorological Society, 2000)In this note, a procedure to construct predictors is suggested that could take advantage of the increasing predictive skill of ENSO models. These so-called secondary forecast models (SFM) attempt to produce a forecast for ... -
Trajectory Models for Heavy Particles in Atmospheric Turbulence: Comparison with Observations
(American Meteorological Society, 2000)The simplest ?random flight? models for the paths of heavy particles in turbulence have been tested against previous observations of the deposition of glass beads from an elevated source in the atmospheric surface layer. ... -
An Integral Formulation for the Dispersion Parameters in a Shear–Buoyancy-Driven Planetary Boundary Layer for Use in a Gaussian Model for Tall Stacks
(American Meteorological Society, 2000)An integral parameterization of the dispersion coefficients σy and σz in a shear?buoyancy-driven atmospheric boundary layer is developed by using a model for the frequency spectrum of eddy energy. The formulation relies ... -
Reflectivity, Rain Rate, and Kinetic Energy Flux Relationships Based on Raindrop Spectra
(American Meteorological Society, 2000)The relationships between radar reflectivity factor Z, rainfall rate R, and rainfall kinetic energy flux E were analyzed based on a multiyear raindrop spectra dataset recorded by a Joss?Waldvogel disdrometer in the Goodwin ... -
Conditional Bias in Radar Rainfall Estimation
(American Meteorological Society, 2000)The goal of this study is to improve understanding of the optimization criteria for radar rainfall (RR) products. Conditional bias (CB) is formally defined and discussed. The CB is defined as the difference between a given ... -
Solar Radiation Absorption due to Water Vapor: Advanced Broadband Parameterizations
(American Meteorological Society, 2000)Accurate parameterizations for calculating solar radiation absorption in the atmospheric column due to water vapor lines and continuum are proposed for use in broadband shortwave radiative transfer codes. The error in the ... -
Surface Wind Speed over Land: A Global View
(American Meteorological Society, 2000)This paper provides a global analysis of surface wind speed (SWS) based on data from 1506 weather stations. It is found that the local variation in monthly normal SWS can generally be captured as a sine function of calendar ... -

Numerical Simulations of Stratus Clouds and Their Sensitivity to Radiation—A RACE Case Study
(American Meteorological Society, 2000)The three-dimensional Canadian Mesoscale Compressible Community model has been run at high resolution (?x = 2 km, ?z = 50 m) to simulate stratus clouds observed on 1 September 1995 during the Radiation, Aerosol and Cloud ... -
Parallels between Statistical Issues in Medical and Meteorological Experimentation
(American Meteorological Society, 2000)The methodology of experimentation, randomization, and statistical analysis in weather modification has many parallels in clinical trials, such as the need for randomization, and the question of inclusion or exclusion of ... -
A Calorimetric Jet Engine Technique for Estimating the Condensed Water Mixing Ratio in Cumulus Clouds for Cloud Physical and Weather Modification Research
(American Meteorological Society, 2000)A technique has been developed for deriving estimates of condensed water mixing ratio in cumulus clouds from measurements of potential temperature in the air in the compressor of a jet engine. Condensate that enters the ... -
Numerical Simulation of Nocturnal Drainage Flows in Idealized Valley–Tributary Systems
(American Meteorological Society, 2000)Numerical simulations of nocturnal drainage flow and transport in idealized valley?tributary systems are compared with the Atmospheric Science in Complex Terrain (ASCOT) meteorological field data and tracer studies from ... -
Automated Monitoring of Snow Cover over North America with Multispectral Satellite Data
(American Meteorological Society, 2000)Current National Oceanic and Atmospheric Administration (NOAA) operational global- and continental-scale snow cover maps are produced interactively by visual analysis of satellite imagery. This snow product is subjective, ...
