cyclone
- Definição1
- A severe weather system with low central pressure. In the fully matured stage, it develops an eye at the center where there is no weather. The eye is surrounded by an inner circle of intense winds and rotating cloud mass. Around the inner circle is the outer circle, which has less fierce weather. The diameter of a cyclone can extend up to 320 miles (500 km).
