RISThe Role of the Divergent Circulation for Large-Scale Eddy Momentum Transport in the Tropics. Part II: Dynamical Determinants of the Momentum Flux
Publisher: American Meteorological Society
Abstract: AbstractThis paper investigates the coupling between the rotational and divergent circulations aiming to explain the observations that show that the tropical eddy momentum flux is due to correlations between divergent eddy ...
The interannual variability of the tropical divergence tilt and its connection with the extratropical circulation
Publisher: American Meteorological Society
Abstract: Previous theoretical work has suggested that the strength of the divergent eddy momentum flux in the deep tropics, due to correlations between rotational zonal velocities and divergent meridional velocities, increases with ...
Coupled Interannual Variability of the Hadley and Ferrel Cells
Publisher: American Meteorological Society
Abstract: AbstractThis work investigates the covariability in the strength of the Hadley and Ferrel cells on interannual time scales using reanalysis data. A significant correlation is found in both hemispheres only during boreal ...
Modeling of Crack Propagation in Thin-Walled Structures Using a Cohesive Model for Shell Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A cohesive interface element is presented for the finite element analysis of crack growth in thin specimens. In this work, the traditional cohesive interface model is extended to handle cracks ...
On the Sensitivity of Zonal-Index Persistence to Friction
Publisher: American Meteorological Society
Abstract: riction is an important parameter in atmospheric modeling that may affect internal variability in a number of ways. It directly damps the annular-mode variability, but it also helps to maintain it through baroclinic ...
Maintenance and Repair Decision Making for Infrastructure Facilities without a Deterioration Model
Publisher: American Society of Civil Engineers
Abstract: In the existing approach to maintenance and repair decision making for infrastructure facilities, policy evaluation and policy selection are performed under the assumption that a perfect facility deterioration model is ...
Updraft/Downdraft Constraints for Moist Baroclinic Modes and Their Implications for the Short-Wave Cutoff and Maximum Growth Rate
Publisher: American Meteorological Society
Abstract: This paper examines the dynamics of moist baroclinic modes, based on the idealized model of moist baroclinic instability devised by Emanuel et al. These authors found that the finite static stability along the downdraft ...
The Relation between Baroclinic Adjustment and Turbulent Diffusion in the Two-Layer Model
Publisher: American Meteorological Society
Abstract: Baroclinic adjustment and turbulent diffusion are two popular paradigms used to describe the eddy?mean flow closure in the two-layer model, with very different implications for the criticality of the system. Baroclinic ...
Bridge Timber Piles Load Rating under Eccentric Loading Conditions
Publisher: American Society of Civil Engineers
Abstract: This study evaluates the load rating procedure that is currently used in rating timber piles supporting multiple-span simply supported bridges. For simplicity, these piles are often rated under concentric loads and the ...
Scaling Analysis for the Interaction between a Buoyant Coastal Current and the Continental Shelf: Experiments and Observations
Publisher: American Meteorological Society
Abstract: This paper addresses how the geometrical parameters (ambient ocean depth, H; bottom slope, α) of coastal bathymetry affect the evolution of buoyant coastal currents flowing over a sloping continental shelf. Scaling arguments ...
