Station observation data is fundamental to data processing and climate analysis. Wind is the horizontal movement of air relative to the ground, and is the main item of ground meteorological observation. Based on wind recording observation data files of more than 2400 stations and hourly wind speed data of automatic stations which started from 2001, integration resulted in the formation of the hourly wind speed series. According to the information characteristics of wind speed data, the quality control is developed based on the hourly wind speed data in China. In 1950s, only a small part of the ground observation stations carried on wind observations, mainly distributed in Northeast China, North China, south of the Yangtze River and so on. The number of wind station increased rapidly after 1970s, gradually close to that of the ground observation station. After 2004, all ground stations realized the hourly observation of wind. By the analysis, the missing measure rate of 76.3% stations was less than 7% in China. Since the beginning of the automatic observation in 2005, the correct rate was higher than 95%. Suspicious rate was highest in 1969 and 1970, respectively, 0.21% and 0.18%. The error rate was higher in 1991, 1998, 1997 and 2004, which were 0.013%, 0.005%, 0.001% and 0.001%, respectively. By using the hourly wind speed dataset, the diurnal variation of wind speed in the Qinghai-Tibetan Plateau was analyzed, the result shows that the maximum wind speed and the average hourly wind speed in spring is higher than the other three seasons. The maximum hourly wind speed in the western Qinghai-Tibetan Plateau is 2 hours earlier than that in the eastern region, and the hourly wind speed in the eastern region is larger than that in the western region. In the eastern (western) part of the Qinghai-Tibetan Plateau, the maximum velocity reaches on local time of 16:00 (14:00), and the minimum wind speed on local time of 06:00 (06:00). In the eastern region, the wind speed on local time of 16:00 is significantly greater than that in the western region on 14:00, the wind speed is 3.75 m·s-1 and 2.90 m·s-1, respectively. In the spring of 1995-2015, both the eastern peak wind and the average wind speed series show significant trends of decreasing (pass the test of significance of 0.01), but there is no significant trend of peak wind speed and mean wind speed series in Western Qinghai-Tibetan Plateau.
