Nontraditional approximation in geophysical fluid dynamics
… dynamics, only the horizontal components of the Coriolis force due to horizontal motions of the fluid are taken into account. All the other components of the Coriolis force, which are called the non-traditional (NT) terms, are considered to be small second order quantities and are usually …

Mass wasting and the Coriolis effect on asteroid Vesta
This work investigates the influence of the Coriolis force on mass motion related to the Rheasilvia impact basin on asteroid (4) Vesta's southern hemisphere. The giant basin is 500km in diameter, with a centre which nearly coincides with the rotation axis of Vesta. The Rheasilvia basin partially …

Stability and transition of three-dimensional rotating boundary layers
… I), type II modes, which arise from a viscous-Coriolis force balance, and neutral modes for a slender cone. The influence of the cone half-angle (ψ) and axial flow strength (s or Ts) on the number and orientation of the spiral vortices is examined, with comparisons made with previous …

The Nocturnal Low-Level Jet in Tropical West Africa: Generation and Representation in Various Data Archives
… rarely gets especially stable at night, (b) the Coriolis force is extremely weak, and (c) the pressure gradient force has a particularly large diurnal cycle (due to the formation of a heat low to the north of the region). In this study, the nocturnal low-level jet is examined using radiosonde and …

An intensive study of the currents and general hydrology of an anomalous upwelling area off South West Africa
… a short relaxation time for pressure gradient forces and the existence of different Velocity layers within the water column. Diurnal sea breezes and landbreezes controlled the currents at 2 and 5m depth with a response time of a few hours but the deeper currents were not directly affected by …

A Study of Immersed Boundary Method in a Ribbed Duct for the Internal Cooling of Turbine Blades
… Ro=0.2; and a negative rotation case at Ro=-0.2. Coriolis force effects are included in the calculation to evaluate the wall model under the influence of these effects which are known to affect shear layer turbulence production on the leading and trailing sides of the duct. Wall model LES …

SIMULATION OF POLLUTANT TRANSPORT RESPONSES TO LOADING AND WEATHER VARIATIONS IN LAKE ST. CLAIR AND THE CONNECTING CHANNELS.
… which includes wind stress, bottom friction, Coriolis force, inflow, outflow and the bottom topography of the lake was developed and verified with field data. The overall root mean square differences between predicted and measured current magnitudes and directions were 1.3 cm.s('-1) and …

Rotating, hydromagnetic laboratory experiment modelling planetary cores
… bulk oscillations of the fluid restored by the Coriolis force. Over-reflection at a shear layer is one mechanism capable of exciting such modes, and we have developed predictions of both onset boundaries and mode selection from over-reflection theory which are consistent with our observations. …

Upwelling dynamics off Monterey Bay : heat flux and temperature variability, and their sensitivities
… occurs when strong alongshore winds and the Coriolis force combine to displace warmer surface waters offshore, leading to upward motions of deeper cooler, nutrient-dense waters to replace these surface waters. Using the models of the MIT Multidisciplinary Simulation, Estimation, and …

Tidal Dissipation in Extrasolar Planets
… explain this, a possible solution is resonantly forced internal oscillation. If the frequency of the tidal forcing happens to land on that of an internal eigenmode, this mode can be resonantly excited to a very large amplitude. The damping of such a mode inside the planet may explain the observed …

Vertical transport at curved ocean fronts
… the front and in geostrophic balance, with the Coriolis force balancing the cross-front pressure gradient. Since geostrophic flow is horizontally nondivergent, vertical motion relies on the ageostrophic component of the flow. Current theories of frontal vertical velocity are based on …

A model of the equatorial deep jets and the role of the horizontal Coriolis parameter
… to the study of the role of the horizontal Coriolis parameter. Most existing analytical models interpret the equatorial deep jets as either low frequency, long Rossby waves or stationary,long Kelvin waves generated at or near the ocean surface. These models are unable to answer the question …

The Role of Kelvin Waves on the Circulation and Salt Transport Variability in the Coastal Bay of Bengal
… internal ocean waves that balance the Earth's Coriolis force against a wave boundary such as a coastline or the equator. In the Indian Ocean, Kelvin waves originate from Wyrtki jets off the east African coast and propagate along the equatorial wave guide until reaching Sumatra, where they …

F-region winds over the central polar cap
… the contributions of the pressure gradient force and Coriolis force to the dayside neutral flow are apparent in addition to ion drag. The nightside flow is mainly controlled by the pressure gradient force.

The effect of gas on multi-stage mixed-flow centrifugal pumps
… gas-liquid conditions. This model based on the forces acting on a single spherical gas bubble, was implemented with a simplified, parametric representation of the flow field in a mixed-flow impeller. In the meridional direction, the Coriolis force opposes the centrifugal force and the adverse …

An experimental study of the spread of buoyant water into a rotating environment
… scale that the dynamics are affected by the Coriolis force arising from the rotation of the earth. This causes the formation of a large outflow gyre near to the source which feeds into a propagating gravity current that is confined to the coast. Previous experimental work in this field has …

Mixing and circulation of meltwater outflow plumes in polar fjords
… from observations, it was conjectured that the Coriolis force has an effect on the circulation in the fjord. Data collected parallel to the glaciers in the fjord supported this conjecture. The field data used as comparisons comprised of a set from a fjord in the southern hemisphere, with a …
