Geography and Climate

At 1,564,116 km2 (603,909 sq mi), Mongolia is the world's 19th-largest country (after Iran). It is significantly larger than the next-largest country, Peru. It mostly lies between latitudes 41° and 52°N (a small area is north of 52°), and longitudes 87° and 120°E. Although Mongolia does not share a border with Kazakhstan, its westernmost point is only 38 kilometres (24 mi) from Kazakhstan.

The geography of Mongolia is varied, with the Gobi Desert to the south and with cold and mountainous regions to the north and west. Much of Mongolia consists of steppes. The highest point in Mongolia is the Khüiten Peak in the Tavan bogd massif in the far west at 4,374 m (14,350 ft). The basin of the Uvs Lake, shared with Tuva Republic in Russia, is a natural World Heritage Site. Most of the country is hot in the summer and extremely cold in the winter, with January averages dropping as low as −30 °C (−22 °F). A vast front of cold, heavy, shallow air comes in from Siberia in winter and collects in river valleys and low basins causing very cold temperatures while slopes of mountains are much warmer due to the effects of temperature inversion (temperature increases with altitude).

In winter the whole of Mongolia comes under the influence of the Siberian Anticyclone. The localities most severely affected by this cold weather are Uvs province (Ulaangom), western Khovsgol (Rinchinlhumbe), eastern Zavkhan (Tosontsengel), northern Bulgan (Hutag) and eastern Dornod province (Khalkhiin Gol). Ulaanbaatar is also strongly affected but not as severely. The cold gets less severe as one goes south, reaching the warmest January temperatures in Omnogovi Province (Dalanzadgad, Khanbogd) and the region of the Altai mountains bordering China. A unique microclimate is the fertile grassland-forest region of central and eastern Arkhangai Province (Tsetserleg) and northern Ovorkhangai Province (Arvaikheer) where January temperatures are on average the same and often higher than the warmest desert regions to the south in addition to being more stable. The Khangai Mountains play a certain role in forming this microclimate. In Tsetserleg, the warmest town in this microclimate, nighttime January temperatures rarely go under −30°C while daytime January temperatures often reach 0°C to 5°C and locals rarely have the stinging sensations associated with early frostbite. In Mongolia, being exposed to temperatures ranging from −30°C to −40°C for more than 60 minutes may increase the risk of frostbite. A strong wind at those temperatures almost certainly leads to frostbite even for Mongolians (who have special physical adaptations to the cold).

The country is subject to occasional harsh climatic conditions known as zud. The annual average temperature in Ulan Bator is 0°C, making it the world's coldest capital city. Mongolia is high, cold, and windy. It has an extreme continental climate with long, cold winters and short summers, during which most of its annual precipitation falls. The country averages 257 cloudless days a year, and it is usually at the center of a region of high atmospheric pressure. Precipitation is highest in the north (average of 200 to 350 millimeters (7.9 to 13.8 in) per year) and lowest in the south, which receives 100 to 200 millimeters (3.9 to 7.9 in) annually. The highest annual precipitation of 622.297mm occurred in the forests of Bulgan Province close to the border with Russia and the lowest of 41.735mm occurred in the Gobi Desert (period 1961–1990). The sparsely populated far north of Bulgan Province averages 600mm in annual precipitation which means it receives more precipitation than Beijing (571.8mm) or Berlin (571mm).

The name "Gobi" is a Mongol term for a desert steppe, which usually refers to a category of arid rangeland with insufficient vegetation to support marmots but with enough to support camels. Mongols distinguish Gobi from desert proper, although the distinction is not always apparent to outsiders unfamiliar with the Mongolian landscape. Gobi rangelands are fragile and are easily destroyed by overgrazing, which results in expansion of the true desert, a stony waste where not even Bactrian camels can survive.
