Statement I: Adiabatic parcels remain on isentropic surfaces.

Statement II: Diabatic heating moves a parcel to a higher isentropic surface.

In the light of the above statements, choose the correct answer.

  • A.Both Statement I and Statement II are correct
  • B.Both Statement I and Statement II are incorrect
  • C.Statement I is correct but Statement II is incorrect
  • D.Statement I is incorrect but Statement II is correct

Answer: A

Both statements are correct and together they define how isentropic analysis works and where it fails. Adiabatic motion is confined to a surface, so trajectories are two dimensional, and heating moves the parcel across surfaces, which is why trajectories through cloud must be computed diabatically. The two statements bound the applicability of the whole technique.
