History

Shanwu,[1] south of present-day Youyuxian, was the seat of Yanmen Commandery during the Qin and Western Han.[2] The post moved to Yinguan southeast of present-day Shuozhou under the Eastern Han and further south to Daixian under the Kingdom of Wei.[1]

Geography

Elevations are generally higher in the south of the county, in which flows the Cangtou River (苍头河); Youyu reaches a north-south extent of 67.7 km (42.1 mi) and east-west width of 45.7 km (28.4 mi). The Great Wall demarcates the northwestern border with Inner Mongolia's Liangcheng and Horinger counties; within the province, Youyu borders Zuoyun County to the east, Shanyin County and Pinglu District to the south.

Climate

Youyu has a monsoon-influenced, humid continental climate (Köppen Dwb), with cold and very dry winters, and warm, humid summers. The monthly 24-hour average temperature ranges from −14.4 °C (6.1 °F) in January to 19.5 °C (67.1 °F) in July, and the annual mean is 3.93 °C (39.1 °F). June thru September accounts for over three-fourths of the 410 millimetres (16 in) of annual precipitation. Due to the high elevation and dry climate, the diurnal temperature variation averages 16 °C (29 °F) annually.
