Match each stage with its energy conversion.

List I

A. Baroclinic growth

B. Barotropic decay

C. Mature stage

List II

P. eddy to mean kinetic energy

Q. available potential to eddy kinetic energy

R. little net conversion

Select the correct match.

  • A.A-P, B-Q, C-R
  • B.A-R, B-P, C-Q
  • C.A-Q, B-R, C-P
  • D.A-Q, B-P, C-R

Answer: D

Baroclinic growth converts available potential energy into eddy kinetic energy, barotropic decay returns eddy kinetic energy to the mean flow, and the mature stage between them shows little net conversion. Following the energy through the cycle, alongside the changing tilt of the disturbance, gives a complete and compact account of the life of a mid-latitude cyclone. Reading the definition literally, rather than recalling a formula, is the reliable route through questions of this shape.
