The weather in Moscow today

Russia's "Viewpoint" reported on the 22nd that Kishkowitz, the chief expert of the Russian Phobos Meteorological Center, said on the 23rd that the weather in Moscow will be extremely cold on the day of Defender of the Motherland.

It is estimated that from the evening of 22nd to the early morning of 23rd, the night temperature in Moscow will be between minus 25 and minus 27 degrees Celsius, and the temperature in some parts of the east will be as low as minus 33 degrees Celsius. The maximum daytime temperature in Moscow is between-14 and-16 degrees Celsius. These indicators are lower than the multi-year standard by 13 to 15 degrees Celsius.

In Moscow 1956, the daily temperature of the Defender of the Motherland was -27. 1 Celsius, which was close to the temperature of this cold wave. In the whole history of temperature observation, the coldest record on this day was -30.5 degrees Celsius in 1945. The Moscow city government advised residents not to go out as much as possible to avoid frostbite.

Regarding the recent sudden cooling and snowstorms in Russia, Europe and parts of the United States, Cherno Kurski, an expert at the Russian Institute of Atmospheric Physics, said that the smaller the temperature difference between the equator and the polar regions, the easier it is to form this unusually cold pattern.

Why is Russia cold?

Most of Russia is located in the north temperate zone, with diverse climate, mainly temperate continental climate, but the climate north of the Arctic Circle belongs to the frigid zone. The temperature difference is generally large, with the average temperature of-18℃~- 10℃ in June and1-27℃ in July.

The average annual temperature in Russia is-1℃ ~ 7℃, with an average of 7℃ during the day and-1℃ at night. Oymyakon village is located in the northeast of Russia, and it is one of the coldest settlements in the world. The annual average temperature of 1 is -50℃, and the lowest temperature in history is -7 1 and 2℃. ?

The cold weather in Oymyakon village is caused by many factors:

1, higher latitude.

High latitude will lead to less solar radiation per unit area. Where is the approximate location of Oymyakon? n， 143？ E, geographically, it belongs to a relatively northerly area. On the winter solstice, the daytime at this latitude is only 3 hours. The following year, from 65438+February to 65438+1October, the sunshine time in Oymyakon is the shortest. 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.

2. Basin topography

Oymyakon is located in a valley surrounded by Chersky Mountains and Vilho Yansk Mountains in the east, west and south, with a basin-like terrain. Warm air from the south is blocked out, while cold air from the north can drive in directly, stagnate and accumulate in the valley, surrounded by mountains, and the cold air flows down the hillside to the basin bottom, making the basin bottom even colder.

3. Living deep inland

The Arctic is mostly ocean. Although the Arctic Ocean is covered by sea ice, there is still heat transferred from under the ice to the lower air on the ice. Oymyakon, on the other hand, lives in the hinterland of eastern Siberia, and the land cools faster than the ocean in winter, which also leads to the local winter temperature being lower than the Arctic.
