Which of the following correctly defines the 'eye' of a cyclone?
It is an area of low pressure
The centre or eye of a tropical cyclone is the area of low pressure and is characterized by little or no wind. In severe cyclones, the eye usually shows up as a circular hole in the central cloud mass. The eye is usually about 40 km in diameter, but can vary from less than 10 km to more than 100 km.
