Arxan (simplified Chinese: 阿尔山; traditional Chinese: 阿爾山; pinyin: Ā'ěrshān; Mongolian: ᠷᠠᠰᠢᠶᠠᠨ ᠬᠣᠲᠠ Arxaan hôt or Рашаан хот; literally spring or spa) is a county-level city of northeastern Inner Mongolia, People's Republic of China. It is under the administration of Hinggan League.

Geography and climate[edit]

Arxan is located in the northwest of Hinggan League, with latitude ranging from 46° 39' to 47° 39' N and longitude ranging from 119° 28' to 121° 23' E; the maximal north-south extent is 118 km (73 mi), while the maximal east-west width is 142 km (88 mi). It spans part of the southwest of the Greater Khingan Range.

Due to the upper-mid latitude and elevation of around 1,000 m (3,280 ft), the climate of Arxan is a subarctic (Köppen Dwc), with strong monsoonal influence, severely cold winters and warm, rainy summers, and low temperatures averaging below freezing for eight calendar months; the monthly 24-hour average temperature stays below freezing for six calendar months. The monthly 24-hour average temperature ranges from −25.1 °C (−13.2 °F) in January to 16.8 °C (62.2 °F) in July, and the annual mean is −2.70 °C (27.1 °F). For much of the year, diurnal temperature variation is large and frequently in excess of 15 °C (27 °F). Nearly three-fourths of the annual precipitation occurs from June to September; however, precipitation is frequent year-round, with both frequency and relative humidity peaking in summer and there being a secondary peak in the winter.
