Statement 2 is correct. Only tropical cyclones, which are intense low-pressure systems, can develop a feature known as an ‘eye’. This eye is a relatively calm, clear region at the center of the storm. Not all cyclones, particularly weaker ones or extra-tropical cyclones, develop a clearly defined eye.
Statement 3 is incorrect. The eye of a tropical cyclone is characterized by subsiding air, which leads to warming. The temperature inside the eye is typically warmer than the surrounding eyewall, sometimes by several degrees Celsius, not lesser by 10°C.
