Explanation:

• Jet Streams occur in the Northern Hemisphere only.

  • Incorrect: Jet streams are fast-flowing, narrow air currents found in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). They occur both in the Northern and the Southern Hemispheres.

• Only Some cyclones develop an eye.

  • Correct: Not all cyclones develop a clear and well-defined eye. The eye of a cyclone is typically formed when the cyclone reaches a certain strength. Weaker cyclonic systems may not have a distinct eye.

• The temperature inside the eye of a cyclone is nearly 10°C lesser than that of the surroundings.

  • Incorrect: Contrary to this statement, the temperature inside the eye of a cyclone is typically warmer than the surrounding areas. The eye is relatively calm and clear compared to the stormy and turbulent regions surrounding it, which are known as the eyewall. only 1 out of the 3 statements is correct.
