AMSU-A Land Surface Emissivity Estimation for Numerical Weather Prediction Assimilation Schemes
(American Meteorological Society, 2005)This study describes the work performed at the European Centre for Medium-Range Weather Forecasts (ECMWF) to estimate the microwave land surface emissivities at Advanced Microwave Sounding Unit (AMSU)-A frequencies within ... -
Flow around a Complex Building: Experimental and Large-Eddy Simulation Comparisons
(American Meteorological Society, 2005)A field program to study atmospheric releases around a complex building was performed in the summers of 1999 and 2000. The focus of this paper is to compare field data with a large-eddy simulation (LES) code to assess the ... -
Variability of Drop Size Distributions: Noise and Noise Filtering in Disdrometric Data
(American Meteorological Society, 2005)Disdrometric measurements are affected by the spurious variability due to drop sorting, small sampling volume, and instrumental noise. As a result, analysis methods that use least squares regression to derive rainfall ... -
Simulation of Crop Yields Using ERA-40: Limits to Skill and Nonstationarity in Weather–Yield Relationships
(American Meteorological Society, 2005)Reanalysis data provide an excellent test bed for impacts prediction systems, because they represent an upper limit on the skill of climate models. Indian groundnut (Arachis hypogaea L.) yields have been simulated using ... -
Rainfall Estimation with a Polarimetric Prototype of WSR-88D
(American Meteorological Society, 2005)As part of the Joint Polarization Experiment (JPOLE), the National Severe Storms Laboratory conducted an operational demonstration of the polarimetric utility of the Norman, Oklahoma (KOUN), Weather Surveillance Radar-1988 ... -
Deducing Ground-to-Air Emissions from Observed Trace Gas Concentrations: A Field Trial with Wind Disturbance
(American Meteorological Society, 2005)Inverse-dispersion techniques allow inference of a gas emission rate Q from measured air concentration. In ?ideal surface layer problems,? where Monin?Obukhov similarity theory (MOST) describes the winds transporting the ... -
Historical Droughts in Central Mexico and Their Relation with El Niño
(American Meteorological Society, 2005)A catalog containing an unprecedented amount of historical data in central Mexico, covering almost six centuries (1450?1900), is used. This is a catalog of agricultural disasters that includes events associated with ... -
Total Surface Area Estimates for Individual Ice Particles and Particle Populations
(American Meteorological Society, 2005)Representations for the surface area of ice particles in terms of the projected area have been developed using two different methods. The first method uses ice particles that are imaged in situ and geometric calculations ... -

A Bulk Microphysics Parameterization with Multiple Ice Precipitation Categories
(American Meteorological Society, 2005)A single-moment bulk microphysics scheme with multiple ice precipitation categories is described. It has 2 liquid hydrometeor categories (cloud droplets and rain) and 10 ice categories that are characterized by habit, size, ... -
Comments on “Estimating Soil Water Contents from Soil Temperature Measurements by Using an Adaptive Kalman Filter”
(American Meteorological Society, 2005)A scheme was proposed by Zhang et al. to estimate soil water content from soil temperature measurements by using an adaptive Kalman filter. Their scheme is based on the fact that soil heat capacity and thermal conductivity ... -
A Case of Rapid Cooling near the Tropopause, near a Line of Tall Thunderstorms
(American Meteorological Society, 1966)Five serial soundings at Ft. Worth, Tex., measured rapid cooling (5?7C in 1½?2 hr) just above the tropopause, near 150 mb, during and then again after the passage of a line of tall thunderstorms. The individual thunderstorm ... -
Physical Characterization of Tropical Oceanic Convection Observed in KWAJEX
(American Meteorological Society, 2005)The Tropical Rainfall Measuring Mission (TRMM) Kwajalein Experiment (KWAJEX) was designed to obtain an empirical physical characterization of precipitating convective clouds over the tropical ocean. Coordinated datasets ... -
A Numerical Study on the Interpretation of Data from Open Atmospheric Balloon Soundings
(American Meteorological Society, 2005)Wrong information may be extracted from balloon soundings if neither appropriate interpretation and processing nor evaluations of certain inevitable distortions or artifacts on atmospheric measurements are performed. A ... -
Use of Salt Lake City URBAN 2000 Field Data to Evaluate the Urban Hazard Prediction Assessment Capability (HPAC) Dispersion Model
(American Meteorological Society, 2005)After the terrorist incidents on 11 September 2001, there is a greatly heightened concern about the potential impacts of acts of terrorism involving the atmospheric release of chemical, biological, radiological, and nuclear ... -
Arctic Mixed-Phase Cloud Properties from AERI Lidar Observations: Algorithm and Results from SHEBA
(American Meteorological Society, 2005)A new approach to retrieve microphysical properties from mixed-phase Arctic clouds is presented. This mixed-phase cloud property retrieval algorithm (MIXCRA) retrieves cloud optical depth, ice fraction, and the effective ... -
A Modified Logarithmic Law for Neutrally Stratified Flow over Low-Sloped Hills
(American Meteorological Society, 2005)The study of the atmospheric boundary layer flow over two-dimensional low-sloped hills under a neutral atmosphere finds numerous applications in meteorology and engineering, such as the development of large-scale atmospheric ... -
Radar Refractivity Retrieval: Validation and Application to Short-Term Forecasting
(American Meteorological Society, 2005)This study will validate the S-band dual-polarization Doppler radar (S-Pol) radar refractivity retrieval using measurements from the International H2O Project conducted in the southern Great Plains in May?June 2002. The ... -
Mesoscale Temperature Variability Below 60,000 Feet
(American Meteorological Society, 1966)Temperature measurements within 200 mi of the airport, and for altitudes up to 60,000 ft, will be necessary for calculating the fuel requirements of supersonic transports. In order to determine an adequate time and space ... -
