Geography and climate

[edit]

Kaiyuan is situated in northeastern Liaoning in the southeastern part of Tieling City on the eastern bank of the middle reaches of the Liao River. It borders Dongfeng County and Qingyuan Manchu Autonomous County to the east, Tieling County to the south, Faku and Changtu counties to the west, and Lishu County (Jilin) to the north. Its administrative area reaches a maximal north–south extent of 86 km (53 mi) and east–west width of 89.4 km (55.6 mi). In the east, the land begins to transition to the foothills of the Changbai Mountains, while the west is marked by the Songliao Plain.

Kaiyuan has a monsoon-influenced humid continental climate (Köppen Dwa), characterised by hot, humid summers and long, cold and windy, but dry winters. The four seasons here are distinctive. A majority of the annual rainfall of 673 mm (26.5 in) occurs in July and August alone. The monthly 24-hour average temperature ranges from −13.4 °C (7.9 °F) in January to 23.9 °C (75.0 °F) in July, and the annual mean is 7.3 °C (45.1 °F).
