风速达到每小时111英里至130英里(179公里至209公里)，三类风暴被认为超过临界值进入“热带气旋”状态。
With winds of 111 to 130 miles (179 kilometers to 209 kilometers) an hour, a Category 3 storm is considered to have crossed the threshold into "major hurricane" status.
冷涡云系的结构可归纳为单纯的冷涡结构和具有锢囚气旋结构两类。

按照强度的不同，热带气旋可以划分为三类：热带低压，热带风暴，以及更强的、在不同地区名字有所不同的一类风暴。
