Explanation:

1. The statement is incorrect: Jet streams occur in both the Northern Hemisphere and the Southern Hemisphere. They are strong, narrow air currents that flow in the upper levels of the atmosphere.

2. The statement is correct: Only some cyclones develop an eye, which is a region of calm and relatively low pressure at the center of the storm. Not all cyclones have an eye.

3. The statement is incorrect: The temperature inside the eye of a cyclone is generally warmer than the surroundings, not cooler. The eye is characterized by clear skies and relatively calm conditions.
