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.

APW的地理分布与实际降水量分布相反,其最大区域却为降水量最小区,受西风带影响,新疆APW模态主要表现全疆一致变化,分布稳定,与降水模态分布差异性大有显著不同,且近40年来无显著变化趋势,表明决定新疆降水差异的根本原因不在于水汽的多少,而是由降水产生的动力条件、水汽辐合和其它因素差异决定的。
