The APW in summer is less than 25 mm which is the least limit value of monsoon areas.This means that Xinjiang is not affected by monsoon.The geographic distribution of APW is adverse with that of precipitation,videlicet,higherAPW values corresponding to lower precipitation values.With the effects of westerly winds,the APW mode presents as an uniform change within Xinjiang area and has a stable distribution.It is very different from Xinjiang rainfall mode which changes a lot spatially.As mentioned above,there is no obvious change during 1961～2000,this indicates that APW is not a dominant factor determining precipitation,it is the result of dynamic condition,water vapor convergence and other causes.
