Abstract:using conventional weather charts, typhoon track, satellite images and relative plot, etc, activity attribute of Typhoon Matsa was analyzed, No. 17 in 2005, the results showed that: Typhoon Matsa was the worst natural disasters in the near future, and created havoc, gale, rainstorm and high tide level for example. The pace would slacken when Matsa developed into typhoon, and it moves more slowly when Matsa developed into a strong typhoon, All of above characteristics show that The more developed Matsa was ,the more slowly it moved. The structure of the spiral cloud and the spiral rain band were the causes of gale and rainstorm. We must observe its movements and weather variations when typhoon arrival. We must grasp happens and development and strength and traverse route of typhoon, these are the important step of aviation meteorological observation and support.
