It was mentioned that typhoons are large-scale weather systems. They can be easily recognized by their eyes, provided that they are intense enough. But what factors decide the size of eyes are still unclear. For example, Typhoon Jelawat in 2000 had an unusually huge round eye which appeared as a 100 km-hole in satellite images. It swept towards the SE China where the eye eventually collapsed. |

Fig. - Typhoon Jelawat had a round and huge eye. As Jelawat travelled westward, its eye became more irregular, but the size remained unusually large. |

Despite the great damage and loss caused by typhoons, it is sometimes enjoyable just to look at how clouds circulate around the eye. Take a look at Typhoon Winnie in 1997. The special eye feature is called double-eye or concentric eye wall. The phenomenon is not quite rare, though. Typhoon Kirogi in 2000 also showed a similar feature. |
 Fig. - Typhoon Winnie possessed a double-eye, cool! |
 Fig. - A closer look at the structure of double-eye depicts the presence of inner and outer eyewalls. |
 Fig. - Typhoon Kirogi also had a double-eye - not as significant as its fellow Winnie. |
