Climatic conditions of Xiate ancient road

The total length of Xiate Ancient Road is120km, which spans two climatic zones in the north and south of Tianshan Mountain. Zhaosu and Xiate hot springs are located on the northern slope of Tianshan Mountain, with humid climate and rainy summer. However, Baicheng County and Nanmu Salter Valley, located on the southern slope of Tianshan Mountain, have a dry climate and high temperature in summer, which leads to the rapid melting of Muzaler Glacier and flash floods. The climate of the ancient road is coldest in January, and the monthly average temperature near Daban is-16 ~-25℃. The highest temperature is in July, and the monthly average temperature is 10- 12℃. A large amount of precipitation in summer is concentrated in July and August, accounting for two-thirds of the annual precipitation. The snow-covered period is 65438 10 from late October to the end of May of the following year, and the snow thickness can reach 65cm, so it is not suitable for crossing. The high temperature in midsummer caused the glaciers to melt rapidly, and the Tehe River in Mouzard surged, cutting off the ancient road and making it impassable for people and animals. The best exploration time is from mid-May to mid-June or from 65438+1October to165438+1October every year.
