What is the coldest country in the same latitude in the world?

Winter in the northernmost part of our country is very cold. If you travel there in winter, you will see snow everywhere in Yuan Ye (the snow-covered period lasts for 6-7 months, including 1 1 in March next year), and the land is white as if it were in the North Pole.

So, are all countries of the same latitude in the world so cold?

No, it's not. Winter in China is exactly the coldest place at the same latitude in the world. If the average temperature in China in June of 5438+ 10 is compared with the countries in the same latitude in the world, the average temperature in Northeast China is lower than that in the same latitude 15 ~ 20℃, in Huanghuai area10 ~/5℃, and in Jiangnan area, it is 6 ~ 10℃. Huma Town, the northernmost county in Heilongjiang Province, China, is located at the same latitude as the British capital London. However, the average temperature in Huma was -28.6℃ in June+10/October in 5438, while it was as high as 4.0℃ in London. Not only is there no permafrost and snow everywhere in London, but winter grass is evergreen and green water often flows. The average temperature is like Hangzhou, 5000 miles south of Huma, China. For another example, the latitude of Tianjin, China is similar to that of Lisbon, the Portuguese capital. The average temperature in Lisbon in 65438+ 10 is close to 10℃, which is the same as that in northern Guangdong and Guangxi. In Tianjin, the temperature in 65438+ 10 is -4.2℃, and only the winter wheat in the field and the pine and cypress in the park make the earth dotted with green. In addition, in June+10/October, 5438, the average temperature in Guilin, China was 8.0℃. Although winter is also green mountains and green waters with beautiful scenery, it still snows for 2 ~ 3 days every year, with frost of 9 ~ 10, while the average temperature in Miami of the same latitude is as high as 19.9℃, with rare frost and snow, and there are coconuts and betel nuts by the sea.

Why does China become the coldest country in the same latitude in the world in winter?

Don't everyone have such a life experience? The cold wave and strong wind stopped in winter, and the weather gradually warmed up under the warm sun, but the good times did not last long. Often the second cold wave goes south one after another, and the temperature drops sharply. If the daily average temperature is plotted into a curve in turn, the shape of the curve is like waves of the sea or steep peaks. It can be seen that the winter in our country is particularly cold, mainly because of the cold wave and cold air that often blows from the north in winter. If there is no cold wave going south and the temperature reaches the zonal average, Harbin will be as warm as Xuzhou and Zhengzhou, Beijing will be warmer than Nanchang and Changsha, and Shanghai will be as warm as Nanning and Guangzhou, and there will be no winter!

Where did these cold waves come from? They are from Siberia in the Soviet Union. Some cold waves also come from the Arctic Ocean, but they also pass through Siberia. Siberia is the coldest place in the northern hemisphere in winter. In Yansk, Oymyakon and Vilho in the Arctic Circle, the average temperature in June is nearly -50℃ at 5438+ 10, and the absolute minimum temperature is as low as -72℃. This cold air blows to our country (although the temperature rises along the way under the baking of Levin and warm land), and it certainly makes the eastern part of our country become the "champion" of low temperature at the same latitude. However, the southwest of Sichuan Province and most parts of Yunnan Province in China are in the dry and warm southwest westerly airflow from southwest Asia in winter, and the climate is very warm: the average temperature in Kunming 10/0 at an altitude of1m is as high as 7.8℃, and the latitude with the east is only 1 167 m, but in Guilin. Another example is Yuanmou in the dry-hot valley of Jinsha River in Yunnan, where the altitude is 1 18m. In June, the temperature was as high as 15.5℃ in 5438+1October, but it was 9.7℃ higher than that in Linxian County, Hunan Province, where the altitude at the same latitude was only 185m. However, we should know that in winter, the temperature in South China will drop by 4 ~ 5℃ on average for every increase of 1km.
