Answer. A tropical cyclone can be divided into five categories depending upon the intensity and its severity where the first category is a less destructive cyclone whereas the last one is the most severe category of cyclones. The first category causes negligible damage with winds of 90 to 125 kph and rests on 8 - 9 on Beaufort Scale whereas the second category cause minor to significant damage with  10 - 11 on a scale and the third one is severe with very destructive winds of 165 - 224 kph with 12 on scale whereas category four and five are also severe tropical cyclones with highest 12 on the scale and of 225 to 279 kph and 280 kph respectively and cause extreme destruction.
