RISSpectral Properties of One-Dimensional Diffusive Systems Subject to Stochastic Forcing
Publisher: American Meteorological Society
Abstract: The vertical wavenumber and frequency spectra of horizontal wind and temperature in stochastically driven systems with diffusion, either due to uniform background eddy and molecular transport, or due to adjustment processes ...
The Impact of NORPEX Targeted Dropsondes on the Analysis and 2–3-Day Forecasts of a Landfalling Pacific Winter Storm Using NCEP 3DVAR and 4DVAR Systems
Publisher: American Meteorological Society
Abstract: During the North Pacific Experiment (NORPEX), both the Navy Operational Global Atmospheric Prediction System and the National Centers for Environmental Prediction (NCEP) operational forecast systems found a 48-h forecast ...
Erratum: “Response Sensitivity and Its Assessment of Nonlinear Vibration Using Lateral–Torsional Coupling Model of Vehicle Transmission System†[Journal of Vibration Acoustics, 2015, 137(3), p. 031013; DOI: 10.1115/1.4029416]
Publisher: The American Society of Mechanical Engineers (ASME)
Error Growth in a Whole Atmosphere Climate Model
Publisher: American Meteorological Society
Abstract: It has been well established that the atmosphere is chaotic by nature and thus has a finite limit of predictability. The chaotic divergence of initial conditions and the predictability are explored here in the context of ...
Enhancing the Weak Signal With Arbitrary High-Frequency by Vibrational Resonance in Fractional-Order Duffing Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When the traditional vibrational resonance (VR) occurs in a nonlinear system, a weak character signal is enhanced by an appropriate high-frequency auxiliary signal. Here, for the harmonic character signal case, the frequency ...
A Numerical Study of Gravity Wave Breaking and Impacts on Turbulence and Mean State
Publisher: American Meteorological Society
Abstract: A model system is established that includes three interactive components: a dynamics model, a turbulence model, and a chemistry model. The dynamics model solves the two-dimensional, nonlinear, nonhydrostatic, compressible, ...
Bifurcation Transition and Nonlinear Response in a Fractional Order System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We extend a typical system that possesses a transcritical bifurcation to a fractionalorder version. The bifurcation and the resonance phenomenon in the considered system are investigated by both analytical and numerical ...
A New Crack Healing Kinetic Model and Application of Crack Healing Diagram
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An internal crack is a common defect which can lead to failure of the material. There are few published studies which can quantitatively predict healed fractions under given conditions such as temperature, pressure and ...
Evidence for Gap Flows in the Birch Creek Valley, Idaho
Publisher: American Meteorological Society
Abstract: field study was conducted of flows in the Birch Creek Valley in eastern Idaho. There is a distinct topographic constriction in the Birch Creek Valley that creates two subbasins: an upper and lower valley. The data were ...
Project Sagebrush: Revisiting the Value of the Horizontal Plume Spread Parameter σy
Publisher: American Meteorological Society
Abstract: he first phase of an atmospheric tracer experiment program, designated Project Sagebrush, was conducted at the Idaho National Laboratory in October 2013. The purpose was to reevaluate the results of classical field experiments ...
