Numerical Simulations of the Wake of Kauai
(American Meteorological Society, 2006)This study uses a series of numerical simulations to examine the structure of the wake of the Hawaiian island of Kauai. The primary focus is on the conditions on 26 June 2003, which was the day of the demise of the Helios ... -
On “Field Significance” and the False Discovery Rate
(American Meteorological Society, 2006)The conventional approach to evaluating the joint statistical significance of multiple hypothesis tests (i.e., ?field,? or ?global,? significance) in meteorology and climatology is to count the number of individual (or ... -
The Synoptic Decomposition of Cool-Season Rainfall in the Southeastern Australian Cropping Region
(American Meteorological Society, 2006)Daily rainfall during the April?October growing season in a major cropping region of southeastern Australia has been related to particular types of synoptic weather systems over a period of 33 yr. The analysis reveals that ... -
An Extended Procedure for Implementing the Relative Operating Characteristic Graphical Method
(American Meteorological Society, 2006)The functional relationship between the relative operating characteristic (ROC) and the economic value (EV) graphical methods have been exploited to develop a hybrid procedure called the extended ROC (EROC) method. The ... -
Improvement in Determination of Ice Water Content from Two-Dimensional Particle Imagery. Part I: Image-to-Mass Relationships
(American Meteorological Society, 2006)Ice water content in natural clouds is an important but difficult quantity to measure. The goal of a number of past studies was to find average relationships between the masses and lengths of ice particles to determine ice ... -
Improvement in Determination of Ice Water Content from Two-Dimensional Particle Imagery. Part II: Applications to Collected Data
(American Meteorological Society, 2006)In Part I of this two-part series, a new relationship for ice particle mass M was derived based on an expanded dataset of photographed ice particles and melted drops. The new relationship resulted in a reduction of nearly ... -
Automatic Detection of Local Cloud Systems from MODIS Data
(American Meteorological Society, 2006)This paper describes an algorithm that is aimed at the identification of cloudy and clear pixels in Moderate-Resolution Imaging Spectroradiometer (MODIS) images to support earth science and nowcasting applications. The ... -
Temporal and Spatial Characteristics of Snowstorms in the Contiguous United States
(American Meteorological Society, 2006)A climatological analysis of snowstorms across the contiguous United States, based on data from 1222 weather stations with data during 1901?2001, defined the spatial and temporal features. The average annual incidence of ... -
Representing Sheared Convective Boundary Layer by Zeroth- and First-Order-Jump Mixed-Layer Models: Large-Eddy Simulation Verification
(American Meteorological Society, 2006)Dry convective boundary layers characterized by a significant wind shear on the surface and at the inversion are studied by means of the mixed-layer theory. Two different representations of the entrainment zone, each of ... -
Bayesian Retrieval of Complete Posterior PDFs of Oceanic Rain Rate from Microwave Observations
(American Meteorological Society, 2006)A new Bayesian algorithm for retrieving surface rain rate from Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) over the ocean is presented, along with validations against estimates from the TRMM Precipitation ... -
Orographic Enhancement of Precipitation over Low Mountain Ranges. Part II: Simulations of Heavy Precipitation Events over Southwest Germany
(American Meteorological Society, 2006)A diagnostic precipitation model that combines linear theory of hydrostatic flow with parameterized microphysics is applied to several stratiform heavy precipitation events over the low mountain ranges of southwestern ... -
Orographic Enhancement of Precipitation over Low Mountain Ranges. Part I: Model Formulation and Idealized Simulations
(American Meteorological Society, 2006)A diagnostic model for simulating orographic precipitation over low mountain ranges is presented. It is based on linear theory of hydrostatic flow over mountains and calculates condensation rates from vertical lifting at ... -
Virtual Towers Using Coherent Doppler Lidar during the Joint Urban 2003 Dispersion Experiment
(American Meteorological Society, 2006)During the Joint Urban 2003 (JU2003) atmospheric field experiment in Oklahoma City, Oklahoma, of July 2003, lidar teams from Arizona State University and the Army Research Laboratory collaborated to perform intersecting ... -
The Asymmetry Parameter of Cirrus Clouds Composed of Hollow Bullet Rosette–Shaped Ice Crystals from Ray-Tracing Calculations
(American Meteorological Society, 2006)Cirrus clouds in the midlatitude and Arctic regions are often composed of bullet rosette?shaped ice crystals. Bullet rosette?shaped ice crystals are composed of a number of bullets radiating from a central point. The bullets ... -
The Effect of Local Atmospheric Circulations on Daytime Carbon Dioxide Flux Measurements over a Pinus elliottii Canopy
(American Meteorological Society, 2006)The daytime net ecosystem exchange of CO2 (NEE) was measured in an even-aged slash pine plantation in northern Florida from 1999 to 2001 using the eddy covariance technique. In August 2000, two clear-cuts were formed ... -
Return Levels of Northern Great Plains Snow Water Equivalents
(American Meteorological Society, 2006)This paper estimates return levels of extreme snow water equivalents (SWE) in the northern Great Plains region, containing North and South Dakota, Iowa, Minnesota, and Nebraska. The return levels are estimated from ... -
Verification of a Mesoscale Data-Assimilation and Forecasting System for the Oklahoma City Area during the Joint Urban 2003 Field Project
(American Meteorological Society, 2006)The National Center for Atmospheric Research (NCAR) and the U.S. Army Test and Evaluation Command have developed a multiscale, rapid-cycling, real-time, four-dimensional data-assimilation and forecasting system that has ... -
Observations and Modeling of Heavy Particle Deposition in a Windbreak Flow
