RISAnalysis of Holding Force Limit and Provision against Dragging Anchor
Publisher: ASCE
Abstract: Analyses of the equilibrium conditions of an anchor and a cable of a ship at anchoring are presented. Three conditions are considered: (1) a part of the cable lies on the seafloor; (2) no part of the cable lies on the ...
A Numerical Experiment on Two-Dimensional Decaying Turbulence on a Rotating Sphere
Publisher: American Meteorological Society
Abstract: A series of numerical experiments on the decaying two dimensional turbulence is performed for a nondivergent barotropic fluid on a rotating sphere by using a high-resolution spectral model with a triangular truncation of ...
Control of Random Yield‐Strength for Mechanism‐Based Seismic Design
Publisher: American Society of Civil Engineers
Abstract: A weak‐beam‐strong‐column philosophy is generally recommended for the design of earthquake‐resistant multistory structures, because the associated overall collapse mechanism exhibits a high ductility against a strong ground ...
Effects of Vertical Wind Shear on the Cumulus Transport of Momentum: Observations and Parameterization
Publisher: American Meteorological Society
Abstract: Dynamical effects of organized cumulus convection on its environment with vertical wind shear are studied. Analyses of the wind field and momentum budget residual for mesoscale convective systems observed during SESAME and ...
Mixed Rossby–Gravity Waves Triggered by Lateral Forcing
Publisher: American Meteorological Society
Abstract: The mechanisms associated with the excitation of mixed Rossby-gravity waves (MRGWs) in the upper troposphere are studied using wind and outgoing longwave radiation (OLR) data from 1979 to 1991. The largest anomalies in ...
Upper Tropospheric Waves in the Tropics. Part I: Dynamical Analysis in the Wavenumber-Frequency Domain
Publisher: American Meteorological Society
Abstract: Space and time spectra of large-scale wave disturbances at the 200 mb level in the latitude belt 20°S to 40°N are studied based on wind data for the period June?August 1967. The kinetic energy of the transient waves shows ...
Mechanism of Heating and the Boundary Layer over the Tibetan Plateau
Publisher: American Meteorological Society
Abstract: The structure of the boundary layer and the mechanism of heating over the Tibetan Plateau are examined using the data obtained from the First GARP (Global Atmospheric Research Program) Global Experiment and the Chinese ...
Seasonal and Interannual Variability of Atmospheric Heat Sources and Moisture Sinks as Determined from NCEP–NCAR Reanalysis
Publisher: American Meteorological Society
Abstract: Using the National Centers for Environmental Predictions (NCEP)?National Center for Atmospheric Research (NCAR) reanalysis, distributions of the heat source Q1 and moisture sink Q2 between 50°N and 50°S are determined for ...
Overreflection of Rossby Waves
Publisher: American Meteorological Society
Abstract: The reflection of the Rossby wave by the shear zone of the basic flow with hyperbolic tangent profile is investigated by examining the eigenfunction of the disturbance equation. The reflection coefficient is evaluated for ...
The Onset and Interannual Variability of the Asian Summer Monsoon in Relation to Land–Sea Thermal Contrast
Publisher: American Meteorological Society
Abstract: The onset and interannual variability of the Asian summer monsoon in relation to land?sea thermal contrast and its contributing factors are studied using a 14-yr (1979?1992) dataset. The onset of the Asian summer monsoon ...
