Given below are two statements
Statement-I: The energy to the tropical cyclone comes from the latent heat released by the cold air.
Statement-II: With the increase in distance from the sea, the force of the cyclone decreases.
The correct answer is
Show Hint
Tropical cyclones form over warm ocean water and are powered by the heat exchange between the sea and the atmosphere.
Concept: Tropical cyclones form over warm ocean water and are powered by the heat exchange between the sea and the atmosphere.
Step 1: Examine Statement-I. The energy of a tropical cyclone comes from the latent heat released when water vapour evaporated from the warm ocean condenses, not from cold air. So Statement-I is incorrect because it wrongly attributes the energy to cold air.
Step 2: Examine Statement-II. A cyclone is fed by moisture and heat from the sea. As it moves inland and the distance from the sea increases, it is cut off from this energy source, so its force (intensity) decreases. Statement-II is correct.
Answer: Option (2) — Only statement-II is correct.
