1. Which of the following correctly explains the role of the Inter-Tropical Convergence Zone (ITCZ) in the Indian monsoon?

A) It creates high-pressure zones over land.

B) Its southward movement triggers the northeast monsoon.

C) Its northward shift draws in southwest monsoon winds.

D) It blocks moisture-laden winds from the Bay of Bengal.

2. Which of the following best describes the Somali Jet’s role in the Indian monsoon?

A) It enhances convection over the Tibetan Plateau

B) It brings cold continental winds to the Himalayas

C) It transports moisture from the Arabian Sea to the Indian subcontinent

D) It suppresses monsoon by increasing upper-level divergence

3. The onset of the Indian monsoon is closely linked with:

A) Arrival of Western Disturbances

B) Northward migration of the Westerlies

C) Shift of subtropical jet stream north of the Himalayas

D) Rise in sea-level pressure over the Bay of Bengal

4. Which of the following locations receives rainfall from both southwest and northeast monsoons?

A) Rajasthan

B) Kerala

C) Tamil Nadu

D) Punjab

5. During an El Niño year, which of the following effects is most likely in India?

A) Above average rainfall across central India

B) Flooding in northwest India

C) Suppression of convection in the Indian Ocean

D) Strengthening of Somali Jet

1. D

Explanation: They are the same phenomena but are called typhoons in the NW Pacific and hurricanes in the Atlantic and NE Pacific.

2. B

Explanation: Due to the Coriolis effect, cyclones rotate anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

3. D

Explanation: High wind shear disrupts the cyclone’s structure and prevents its strengthening.

4. A

Explanation: Doppler radar detects wind patterns, rainfall intensity and rotation, helping track cyclones and tornadoes.

5. C

Explanation: Warm ocean water evaporates, and as this water vapour condenses, latent heat is released, powering the cyclone.
