Based on the precipitation,temperature,sunshine duration,mean wind speed,average relative humidity,and average vapor pressure data at 13meteorological stations in the Western Route of South-to-North Water Diversion Project and adjacent regions over the past 60years,the Mann-Kendall test,Hurst coefficient method,and wavelet method were used to perform the trend,continuity,and periodicity analysis on these meteorological factors.The results indicated that(1)the temperature at each station increases significantly,especially in the winter;(2)annual precipitation at 92%of total stations has an insignificant increasing trend,but precipitation has a significant increasing trend in the spring;and(3)annual sunshine duration at 64%of total stations shows a decreasing trend.Stations that have apparent variation trends of meteorological factors often belong to headwater catchment.Hurst coefficients of meteorological factors are were all greater than 0.5,which indicated a positive long-term continuity and that the variation trend in future is similar to that in the past.Morover,each meteorological factor sequence had an obvious cycle of 6to 18years.
