Climatic characteristics of Oymyakon

Oymyakon is located in the climate zone of eastern Siberia, which has the most remarkable continental climate characteristics, characterized by huge temperature difference between winter and summer and between day and night. Winter is long and cold, with the average temperature below -40℃ in three months of the year, the coldest month is 65438+1October, and the average temperature in 65438+1October is about -47℃. Summer is cool but short. The average temperature in July is 13 ~ 16℃, and the average annual temperature is about-16℃.

Oymyakon's land is permafrost, so residents' houses must be built on wooden stakes buried deep underground, at least 1 m away from the ground, and cannot be directly built on permafrost, otherwise the indoor hot air will melt the frozen soil foundation and the house will collapse, so that the house is not only particularly thick, but also has four or five floors of doors and windows to prevent the outdoor cold from invading.

The geographical environment of Oymyakon:

1, geographical location

Oymyakon (оймякон) is a basin in the northeast of Siberia, Russia, with an altitude of about 74 1 meter. 350 kilometers south of the Arctic Circle, it 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 Siberian indigenous Erka River. It is high in the east, south and west, low in the north, and the climate is extremely cold. Together with Yersk, it is called the "cold pole" in the northern hemisphere.

2. The reason for the cold

High latitude will lead to less solar radiation per unit area. The approximate location of Oymyakon is 63 north latitude and 0/43 east longitude, which belongs to a relatively northerly area. Every winter solstice, the daytime at this latitude is only 3.5 hours. At this time, it is also in the polar night period of the Arctic Circle. Because it is close to the Arctic Circle, the sunshine time in this area is not much longer than that in the Arctic. But they also live inland, far away from any marine water body that has a moderate impact on the local weather.
