Question

Q. Which of the following conditions is not favourable for formation and intensification of tropical storms?

• A.
  Presence of the Coriolis Force
• B.
  Large sea surface with a temperature higher than 27 ‘C
• C.
  Pre-existing strong-high pressure area
• D.
  Variations in the vertical wind speed

Answer 1

The correct option is C

Pre-existing strong-high pressure area

Explanation:

Tropical cyclones originate and intensify over warm tropical oceans. The conditions favourable for the formation and intensification of tropical storms are Presence of the Coriolis Force, Large sea surface with a temperature higher than 27 ‘C, Pre-existing weak-low pressure area or low-level cyclonic circulation, Upper divergence above the sea level system and small variations in the vertical wind speed.
