Impact of Configurations of Rapid Intermittent Assimilation of WSR-88D Radar Data for the 8 May 2003 Oklahoma City Tornadic Thunderstorm Case
Publisher: American Meteorological Society
Abstract: Various configurations of the intermittent data assimilation procedure for Level-II Weather Surveillance Radar-1988 Doppler radar data are examined for the analysis and prediction of a tornadic thunderstorm that occurred ...
Simulations of Atmospheric Rivers, Their Variability and Response to GlobalWarming Using GFDL’s New High Resolution General Circulation Model
Publisher: American Meteorological Society
Abstract: A 50km resolution GFDL AM4 well captures many aspects of observed atmospheric river (AR) characteristics including the probability density functions of AR length, width, length-width ratio, geographical location, the ...
Analytical Solution to Ultimate Lateral Pressure on a Vertical Plate in Undrained Soil
Publisher: ASCE
Abstract: For a vertical plate emerging on the surface of undrained cohesive soil, the adhesion between the plate and soil considerably impacts the lateral soil pressure on it. However, very few closed-form solutions have been ...
An Analytic Study of the Baroclinic Adjustment in a Quasigeostrophic Two-Layer Channel Model
Publisher: American Meteorological Society
Abstract: This paper reports on a study of quasi-linear baroclinic adjustment in a quasigeostrophic two-layer model with a constant baroclinic shear and an Ekman damping that is equal at the upper and lower boundaries. An analytic ...
A Physical Interpretation for the Stability Property of a Localized Disturbance in a Deformation Flow
Publisher: American Meteorological Society
Abstract: The relationship between the local shape of an unstable disturbance and the basic deformation field has been put forward by Mak and Cai as a general condition for barotropic instability of a zonally varying nondivergent ...
Sliver Generation Reduction in Trimming of Aluminum Autobody Sheet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aluminum autobody sheets produce appreciable amounts of slivers during trimming operations when trimmed with dies conventionally designed for steel sheets. The slivers can be carried through ...
On the Formulation of Linear Instability and Forced Problems for a Zonally Varying Basic State in the Complex Domain
Publisher: American Meteorological Society
Abstract: It is shown that when the basic state has zonal variation, the linearized operator of an atmospheric spectral model acts on the perturbation spectral coefficients of both the nonnegative zonal indexes and their conjugates. ...
Noniterative Method of Solving the GPS Double-Differenced Pseudorange Equations
Publisher: American Society of Civil Engineers
Abstract: The global positioning system (GPS) is a constellation of 24 navigation satellites developed and deployed by the U.S. Department of Defense to provide worldwide real-time positioning capability to its numerous users around ...
High-Order Monotonic Numerical Diffusion and Smoothing
Publisher: American Meteorological Society
Abstract: High-order numerical diffusion is commonly used in numerical models to provide scale selective control over small-scale noise. Conventional high-order schemes have undesirable side effects, however: they can introduce noise ...
