Generation of Ensemble Mean Precipitation Forecasts from Convection-Allowing Ensembles
Publisher: American Meteorological Society
Abstract: AbstractMethods for generating ensemble mean precipitation forecasts from convection-allowing model (CAM) ensembles based on a simple average of all members at each grid point can have limited utility because of amplitude ...
Mechanical Characterization of a Dynamic and Tunable Methacrylated Hyaluronic Acid Hydrogel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hyaluronic acid (HA) is a commonly used natural polymer for cell scaffolding. Modification by methacrylate allows it to be polymerized by free radicals via addition of an initiator, e.g., lightsensitive Irgacure, to form ...
An Analytic Scaling Law for the Depositional Growth of Snow in Thin Mixed-Phase Layer Clouds
Publisher: American Meteorological Society
Abstract: In various practical problems, such as assessing the threat of aircraft icing or calculating radiative transfer, it is important to know whether mixed-phase clouds contain significant liquid water content. Some mixed-phase ...
An Examination of a Model's Components during Tropical Cyclone Recurvature
Publisher: American Meteorological Society
Abstract: The main goal of this study is to investigate the relative contributions from the components of dynamics and physics of a forecast model, toward the understanding of the recurvature dynamics of hurricanes. A number of ...
Outlier Detection in Multivariate Hydrologic Data
Publisher: American Society of Civil Engineers
Abstract: The existence of extreme events in data sets can distort the accuracy of computed statistics. Some favor censoring outliers while others oppose censoring measured values. Detection methods are available for use in the ...
Structural Behavior of Thin-Walled Metal Silos Subject to Different Flow Channel Sizes under Eccentric Discharge Pressures
Publisher: American Society of Civil Engineers
Abstract: The condition of eccentric discharge is known to be one of the most critical for the design of thin-walled cylindrical metal silos. Significant progress has been made in recent years in devising a relatively realistic set ...
The Effects of Fuel Characteristics on Stoichiometric Spark-Assisted HCCI
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characteristics of fuel lean homogeneous charge compression ignition (HCCI) operation using a variety of fuels are well known and have been demonstrated using different engine concepts in ...
NAM Model Forecasts of Warm-Season Quasi-Stationary Frontal Environments in the Central United States
Publisher: American Meteorological Society
Abstract: Using a composite procedure, North American Mesoscale Model (NAM) forecast and observed environments associated with zonally oriented, quasi-stationary surface fronts for 64 cases during July?August 2006?08 were examined ...
Stress Concentration Solution for a 2D Dent in an Internally Pressurized Cylinder
Publisher: American Society of Civil Engineers
Abstract: Dent imperfections in internally pressurized shells have a stress concentration effect. In cylindrical shells under internal pressure, such as pipelines, stress concentrations associated with dent imperfections can degrade ...
Biomechanical Inferences about the Origins of Bipedal Locomotion from Ancient African Femora
Publisher: American Society of Civil Engineers
Abstract: Reported here are the diaphyseal cross-sectional geometrical properties of two fossilized femora from Kenya dated at
