RISOscillating Journal Bearings Under Steady Load: A Numerical Study of Limiting Cases
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This note provides a more extensive assessment of bearing performance for steadily loaded oscillating journal bearings using the mobility method of solution. Even with significantly large journal oscillation amplitudes, ...
The Synoptic Verisimilitude of a Mid-Latitude Cyclone Generated in a Southern Hemisphere General Circulation Model
Publisher: American Meteorological Society
Abstract: A detailed examination has been made of the synoptic and physical behavior of an initially diffluent, large-amplitude but representative trough that formed in a Southern Hemisphere general circulation model after approximately ...
Three- and Four-Dimensional Variational Assimilation with a General Circulation Model of the Tropical Pacific Ocean. Part I: Formulation, Internal Diagnostics, and Consistency Checks
Publisher: American Meteorological Society
Abstract: Three- and four-dimensional variational assimilation (3DVAR and 4DVAR) systems have been developed for the Océan Parallélisé (OPA) ocean general circulation model (OGCM) of the Laboratoire d'Océanographie Dynamique et de ...
Sea Level Assimilation Experiments in the Tropical Pacific
Publisher: American Meteorological Society
Abstract: Idealized twin experiments with the HOPE ocean model have been used to study the ability of sea level data assimilation to correct for errors in a model simulation of the tropical Pacific, using the Cooper and Haines method ...
Initialization and Data Assimilation in Models of the Indian Ocean
Publisher: American Meteorological Society
Abstract: Numerical experiments have been conducted to investigate the effect of updating models of the Indian Ocean using simulated temperature (mass) and velocity data. Two models are used: a linear reduced gravity model with one ...
A Remote Acoustic Wind Sensor for Airport Approaches
Publisher: American Meteorological Society
Abstract: A Doppler acoustic system was installed on the approach to the Los Angeles International Airport in a demonstration of its capability of remotely measuring wind and wind shear in a real airport environment. The instrument ...
Impact of Ocean Observation Systems on Ocean Analysis and Seasonal Forecasts
Publisher: American Meteorological Society
Abstract: The relative merits of the Tropical Atmosphere?Ocean (TAO)/Triangle Trans-Ocean Buoy Network (TAO/TRITON) and Pilot Research Moored Array in the Tropical Atlantic mooring networks, the Voluntary Observing Ship (VOS) ...
Toward the Use of Altimetry for Operational Seasonal Forecasting
Publisher: American Meteorological Society
Abstract: The TOPEX/Poseidon and ERS-1/2 satellites have now been observing sea level anomalies for a continuous time span of more than 6 yr. These sea level observations are first compared with tide gauge data and then assimilated ...
A Simulation of Variability of ENSO Forecast Skill
Publisher: American Meteorological Society
Abstract: In many prediction schemes, the skill of long-range forecasts of ENSO events depends on the time of year. Such variability could be directly due to seasonal changes in the basic ocean-atmosphere system or due to the state ...
Three- and Four-Dimensional Variational Assimilation with a General Circulation Model of the Tropical Pacific Ocean. Part II: Physical Validation
Publisher: American Meteorological Society
Abstract: Three- and four-dimensional variational assimilation (3DVAR and 4DVAR) systems have been developed for the Océan Parallélisé (OPA) ocean general circulation model of the Laboratoire d'Océanographie Dynamique et de Climatologie. ...
