Which self-regulating behaviour does the eddy transport produce?

  • A.The temperature gradient increases steadily until convection begins across the whole of the middle latitudes
  • B.No regulation occurs
  • C.The eddies grow without limit until the available potential energy of the atmosphere is entirely exhausted
  • D.The atmosphere is held near marginal baroclinic stability

Answer: D

Eddies reduce the gradient that created them, so the atmosphere is maintained close to a state of marginal stability in which growth and transport are in rough balance. This baroclinic adjustment idea explains why observed mid-latitude lapse rates and gradients vary so little. The regulation is not perfect, which is why individual storms and quiet spells still occur. The quantity that varies and the quantity that does not are worth naming before any substitution is attempted.
