Exempel på hur man kan använda GEOSTROPHIC i en mening

• The barotropic vorticity equation assumes the atmosphere is nearly barotropic, which means that the direction and speed of the geostrophic wind are independent of height.
• As the air accelerated, the deflection would increase until the Coriolis force's strength and direction balanced the pressure gradient force, a state called geostrophic balance.
• Although the stationary front's position may not move, there is air motion as warm air rises up and over the cold air, responsive to the geostrophic induced by frontogenesis.
• Above the PBL is the "free atmosphere", where the wind is approximately geostrophic (parallel to the isobars), while within the PBL the wind is affected by surface drag and turns across the isobars (see Ekman layer for more detail).
• Otherwise, if geostrophic wind blows from warm air to cold air (warm advection) the wind will turn clockwise with height, also known as wind veering.
• Such isobaric surfaces will also be isothermal surfaces, hence (from the thermal wind equation) the geostrophic wind will not vary with depth.
• The concept of colder, dense air "wedging" under the less dense warmer air is too simplistic, as the upward motion is really part of a maintenance process for geostrophic balance on the rotating Earth in response to frontogenesis.
• While the SECC is geostrophic in nature, the physical mechanism for its appearance is less clear than with the NECC; that is, Sverdrup theory does not obviously explain its existence.
• Ekman transport causes water to flow toward the center of the gyre, creating a sloped sea-surface, and initiating geostrophic flow.
• A barotropic model tries to solve a simplified form of atmospheric dynamics based on the assumption that the atmosphere is in geostrophic balance; that is, that the Rossby number of the air in the atmosphere is small.
• Ekman transport causes water to flow toward the center of the gyre in all locations, creating a sloped sea-surface, and initiating geostrophic flow (Colling p 65).
• Vilhelm Bjerknes generalized Helmholtz's vorticity equation (1858) and Kelvin's circulation theorem (1869) to inviscid, geostrophic, and baroclinic fluids, i.
• The principle of geostrophy or geostrophic balance is useful to oceanographers because it allows them to infer ocean currents from measurements of the sea surface height (by combined satellite altimetry and gravimetry) or from vertical profiles of seawater density taken by ships or autonomous buoys.
• Like in geostrophic balance, the flow is frictionless and, for steady-state motion, the trajectories follow the isobars.
• The potential for CSI to enhance the descent of sting jets is quantified by downdraught slantwise convective available potential energy (DSCAPE), which measures the theoretical maximum kinetic energy that a descending air parcel may attain while remaining saturated and conserving geostrophic absolute momentum.
• Strictly speaking, QG theory approximates both the advected momentum and the advecting velocity as given by the geostrophic wind.
• Ageostrophy or (ageostrophic flow) is the difference between the actual wind or current and the geostrophic wind or geostrophic current.
• The climate of Panamá is largely affected by the position of a low atmospheric pressure zone known as the Intertropical Convergence Zone (ITCZ) which also affects seasonal evolution of geostrophic currents in the Panamá Bight.
• The basin-wide MOC strength and vertical structure are estimated via Ekman transports by satellite scatterometer measurements and the geostrophic and direct current observations.
• Once the surface forcing decreases, the vertical heat transfer due to convection abates, leading to horizontal transfer associated with eddying on geostrophic scale.
