This paper has discussed some problems of typhoon “Chebi”， including its track and structure. Influenced by the orographic depression first and tropical cloud cluster later，typhoon “Chebi” turned to right and left before its landfall. The typhoon had the characters of small scale,strong intensity and elliptic eye. It is elliptic eye that could be used to explain why the atmospheric pressure of the coastal sampling stations rose obviously in 3 to 9 hours before the typhoon passing. The rough weather took place in the region nearby and right to the eye. The strong gust and the storm surge caused the most of disaster.
