Consider the following statements:

  1. 1.Jet streams occur in the Northern Hemisphere only.
  2. 2.Only some cyclones develop an eye.
  3. 3.The temperature inside the eye of a cyclone is nearly 10°C less than that of the surroundings.

Which of the statements given above is/are correct?

  1. A.1 only
  2. B.2 and 3 only
  3. C.2 only
  4. D.1 and 3 only
▶ Answer & Explanation

Correct answer: C. 2 only

Jet streams are high-altitude air currents that can occur in both the Northern and Southern Hemispheres, influencing weather patterns. Not all tropical cyclones form a distinct eye; this feature is characteristic of mature and intense storms. The eye of a cyclone is an area of calm, clear weather, and the air within it is warmer than the surrounding eyewall due to descending air.
