Official UPSC Answer KeyUPSC Prelims 1999 • Geography

Correct Answer: Option (B) — B

Concept & Option Breakdown

Standard Reference Verified

In a vertical cross-section of a mature cyclone:

  • C represents the central 'Eye', characterized by subsiding air, calm winds, and clear skies.
  • B represents the 'Eye Wall' surrounding the central eye, where the strongest pressure gradient, maximum updraft velocity, and dense cumulonimbus towers occur. It produces the most severe weather, including torrential downpours and intense thunderstorms.
  • A and D represent outer spiral rainbands and peripheral subsidence zones with lighter, more intermittent precipitation.
Elimination Heuristic & Exam Approach

In any cyclone cross-section diagram, the region adjacent to the central eye (the eyewall, marked B) always represents maximum wind velocity and torrential precipitation.
