Oymyakon is a basin in the northeast of Siberia, Russia, which is located 350 kilometers south of the Arctic Circle and is under the jurisdiction of the Russian Republic of Sakha. Oymyakon is located in the center of the basin of the same name in the upper reaches of the Indigilka River in Siberia. The terrain in the east, south and west is higher, and the terrain in the north is lower. It is called the cold pole of the northern hemisphere together with Yeung Sik. The lowest temperature measured in oimiyakan, Siberia, is -7 1.2℃, which earned it the title of cold pole in the northern hemisphere.

The approximate position of Oymyakon is 63 degrees north latitude and 0/43 degrees east longitude. At this latitude, the time of day is only 3.5 hours. At this time, the arctic circle is also in the extreme night period. Because of its geographical location near the Arctic Circle, the sunshine time here is not much longer than that in the North Pole. It is located inland, far away from any marine water body that may have a moderate impact on the local weather.

Warm air from the south is blocked, and cold air from the north can enter directly, stagnate and accumulate in the valley and be surrounded by surrounding mountains. The cold air flow sinks to the bottom of the basin along the hillside, making the bottom of the basin colder. Oimiakang people are afraid of cold. When the temperature is below MINUS 50 degrees. C~-60？ C, they must be fully armed, and the time to go out within 20 minutes will be shortened. They will be in danger of frostbite. Their toilets are outdoors, and ventilation before and after will make people faint. ?
