Which residual circulation is used alongside that diagnostic?

  • A.The Lagrangian circulation
  • B.The Stokes drift, which is the net displacement of a parcel over a complete cycle of the wave motion
  • C.The transformed Eulerian mean circulation
  • D.The Eulerian mean circulation, in which the eddy fluxes and the mean advection largely cancel one another

Answer: C

The transformed Eulerian mean circulation approximates the mean Lagrangian motion of air parcels by combining the Eulerian mean with the eddy induced Stokes drift. In the conventional Eulerian mean the eddy fluxes and the mean advection largely cancel, obscuring the net transport. The transformed framework makes the Brewer-Dobson circulation visible as a single meridional cell. The shared properties explain why these belong to one family, and the differences explain why more than one exists.
