advection Usage Examples

Preposition: of

  • tracer: By considering the equation for advection of a passive tracer, explain why we generally take a time scale to be.
  • air: Here the spherical glyphs represent particle advection of heated air around a room.
  • vapor: References Blackburn, M. ( 1997 ) Advection of water vapor and the cold polar tropopause bias in Eulerian GCMs.
  • gradient: As an example of advection let us consider 1D advection of a constant gradient of some scalar.

Adjective modifier

  • chaotic: Chaotic advection has been used in the analysis of mixing.
  • horizontal: Thus in regions where there is strong horizontal advection our 1-d model can not hope to reproduce the patterns in biological activity.
  • thermal: Ascent occurs ahead of a surface warm anomaly warm advection ( Laplacian of the thermal advection ).
  • vertical: The vertical advection is performed by considering control volumes, which are remapped on to the original or levels.
  • cold: The process by which this cold, dry air moves horizontally into an area is known as cold air advection.

Modifies a noun

  • scheme: Some simple tests are made to quantify the dissipation inherent in the advection scheme.
  • fog: Advection fog occurs when warm air flows over a cool surface ( for example, over a cool ocean current ).
  • speed: But the velocity relative to the ground depends not only on the phase velocity of the disturbances but also on the advection speed.
  • process: A paper is in preparation on this work, and details of the water vapor advection processes involved are under investigation.
  • problem: The detailed study of a specific time integrator for numerical simulations of advection problems with small diffusion.

Noun used with modifier

  • contour: A contour advection run started on the 10th shows a very similar feature.
  • particle: Here the spherical glyphs represent particle advection of heated air around a room.
  • water: Another important practice in analyzing nonlinear water waves is to study the water particle advection in the history of a simulation.
  • vorticity: The process, positive vorticity advection, is usually abbreviated to PVA.
  • tracer: Tracer advection is a longstanding and notoriously difficult problem with numerical models, and a severe limitation on their validity.
  • heat: Update buoyancy after heat advection and freshwater inflow, if used.
