Abstract:[Objective] The change characteristics of wind speed and sunshine duration in Bosten Lake Basin of Xinjiang Uygur Autonomous Region were illustrated to provide scientific evidences for the industrial and agricultural production, ecological environment construction of this river basin.[Methods] Using conventional statistics, Mann-Kendall mutation analysis and wavelet analysis methods, we analyzed the average diurnal variations of wind speed and sunshine duration of the Bosten Lake Basin, based on 4 weather stations data recorded from 1961 to 2013.[Results] In the past 53 years, the average wind speed obviously decreased in Bosten Lake Basin, with an average decrease rate approximately 0.092[(m·s)/10 a]. In spring, summer and autumn, the variation amplitudes of the plain surrounding the lake and the basin area were greater than that of the north part and the northwest mountain area. However, in winter, the spatial variation was opposite. The average diurnal variation of sunshine duration also showed distinct decrease, with a rate of approximate 59.11 h/10 a. The decrease trend got the peak in the years of 1985 to 1986. The spatial change in the north subarea was big, and small in the south part.[Conclusion] Wind speed and sunshine duration correlated in the study area well.
