RISOn the Equilibrium-State Roll Vortices and Their Effects in the Hurricane Boundary Layer
Publisher: American Meteorological Society
Abstract: n this study, the authors numerically simulate roll vortices (rolls) generated by the inflection-point instability in the hurricane boundary layer (HBL). The approach is based on embedding a two-dimensional high-resolution ...
On the Generation of Roll Vortices due to the Inflection Point Instability of the Hurricane Boundary Layer Flow
Publisher: American Meteorological Society
Abstract: orizontal roll vortices, or rolls, are frequently observed in the hurricane boundary layer (HBL). Previous studies suggest that these rolls can be generated by the inflection point instability of the HBL flow. In this study ...
On the Characteristics of Linear-Phase Roll Vortices under a Moving Hurricane Boundary Layer
Publisher: American Meteorological Society
Abstract: AbstractPrevious theoretical and numerical studies only focused on the formation of roll vortices (rolls) under a stationary and axisymmetric hurricane. The effect of the asymmetric wind structure induced by the storm ...
Assimilation of DMSP and TOVS Satellite Soundings in a Mesoscale Model
Publisher: American Meteorological Society
Abstract: A modeling investigation explores the impacts of the assimilation of satellite-retrieved soundings on forecast error in the Fifth-Generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale ...
Numerical Simulation of an Intense Squall Line during 10–11 June 1985 PRE-STORM. Part II: Rear Inflow, Surface Pressure Perturbations and Stratiform Precipitation
Publisher: American Meteorological Society
Abstract: An intense rear-inflow jet, surface pressure perturbations, and stratiform precipitation associated with a squall line during 10?11 June 1985 are examined using a three-dimensional mesoscale nested-grid model. It is found ...
Numerical Simulation of an Intense Squall Line during 10–11 June 1985 PRE-STORM. Part I: Model Verification
Publisher: American Meteorological Society
Abstract: A 24-h nested-grid simulation of an intense squall line during the 1985 PRE-STORM experiment is presented using an improved version of the Pennsylvania State University/National Center for Atmospheric Research three-dimensional ...
On the Sensitivity of Hurricane Intensity and Structure to Horizontal Tracer Advection Schemes in FV3
Publisher: American Meteorological Society
Heterogeneity in Valuation of Travel Time Reliability and In-Vehicle Crowding for Mode Choices in Multimodal Networks
Publisher: American Society of Civil Engineers
Abstract: To support scientific planning and management of transportation systems, this paper carries out comprehensive stated preference (SP) surveys to investigate commuters’ mode choice behavior in multimodal networks. Efficient ...
Evaluation of Meteorological Analyses, Simulations, and Long-Range Transport Calculations Using ANATEX Surface Tracer Data
Publisher: American Meteorological Society
Abstract: Perfluorocarbon tracer data collected during the Across North America Tracer Experiment (ANATEX) are used to evaluate different meteorological analysis, simulations, and long-range transport calculations. Three basic types ...
Fatigue Damage of Aluminum Alloy Spot-Welded Joint Based on Defects Reconstruction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional (3D) reconstruction and finite element method are combined to study the damage behavior of aluminum alloy resistance spot-welded joints. Fatigue damage of spot-welded joints under different cyclic loading ...
