Match each system with the precipitation structure it produces.
List I
A. Warm front
B. Cold front
C. Tropical cyclone
D. Sea breeze front
List II
1. spiral rainbands around an eye
2. widespread stratiform rain ahead of it
3. a line of shallow convection inland
4. a narrow band of convective showers

  • A.A-2, B-4, C-3, D-1
  • B.A-3, B-1, C-4, D-2
  • C.A-2, B-4, C-1, D-3
  • D.A-4, B-2, C-1, D-3

Answer: C

Correct answer: A-2, B-4, C-1, D-3

Each system’s precipitation reflects how steeply it lifts the air. A warm front has a gentle slope, so it lifts a deep layer slowly over a wide area and gives widespread stratiform rain ahead of it. A cold front lifts abruptly, giving a narrow band of convective showers along the boundary. A tropical cyclone organises its convection into spiral rainbands around the eye, and a sea breeze front produces a line of shallow convection where it penetrates inland.
