Which of the following statements regarding tropical cyclones is/are correct ? 1. These storms develop during the summer and autumn in every tropical ocean except the South Atlantic and eastern South Pacific Oceans. 2. Tropical cyclones that occur in the North Atlantic and eastern North Pacific Oceans are known as typhoons. 3. Tropical cyclones that occur in the Indian and South Pacific Oceans are called cyclones. Select the answer using the code given below :
Explanation
The correct option is C (1 and 3 only) based on the following geographical facts:
- Statement 1 is correct: Tropical cyclones require warm sea surface temperatures (above 26.5°C) and low vertical wind shear. These conditions are rarely met in the South Atlantic and eastern South Pacific due to cooler waters and high wind shear, making cyclone formation extremely rare there.
- Statement 2 is incorrect: Tropical cyclones in the North Atlantic and eastern North Pacific are called Hurricanes. The term Typhoon is specifically used for storms in the Northwest Pacific Ocean (near East Asia).
- Statement 3 is correct: The term Cyclone is used for these storms in the Indian Ocean and the South Pacific Ocean (including the waters around Australia).
