Just entering 2021, why is the weather extremely cold, exceeding the low temperature level of any previous winter

元旦剛過，北方的氣溫低至零下11攝氏度，這是什么概念，先描述下癥狀：

Just after New Year's Day, the temperature in the north was as low as minus 11 degrees Celsius. What is this concept? First describe the symptoms:

 

1、走出屋外，臉上如刀割一般，頓時知道什么是威風凜凜。

1. When I walked out of the house, my face was cut like a knife, and I knew what majesty was.

2、手腳不敢露出，不然可能瞬間被凍僵。

2. Don't dare to show your hands and feet, or you may be frozen instantly.

3、哈爾濱的溫度零下30攝氏度，幾乎潑水成冰，人們不能出去購物，一不小心，呼出的氣體直接成冰棍。

3. The temperature in Harbin is minus 30 degrees Celsius, almost splashing water into ice. People cannot go shopping. If they are not careful, the exhaled air directly turns into popsicles.

分析下什么原因造成的如此低溫？What causes such low temperature under analysis?

雖然，這樣的極端氣溫，影響了人們的生活，但是，確實一種好現(xiàn)象。

Although such extreme temperatures have affected people's lives, it is indeed a good phenomenon.

 

 

 

國家對于污染問題，大氣污染治理極其重視，對于各種工業(yè)生成，進行了遏制，比如，印刷行業(yè)，廢舊氣體排出的冶鐵企業(yè)，進行了限制或者定時開工，目的就是減輕對大氣的污染，提倡“綠水青山，金山銀山”。

 The state attaches great importance to pollution problems and air pollution control. Various industrial production has been curbed. For example, the printing industry and iron smelting enterprises that emit waste gases have restricted or started construction regularly. The purpose is to reduce air pollution and advocate "Green water and green mountains, gold and silver mountains".

霧霾的治理已經(jīng)取得了非常明顯的成效，大氣環(huán)境變得非常的清晰，尤其城市溫室效應(yīng)，大大減弱，同樣的溫度，在無霧霾的情況下，天氣就會非常的寒冷，因為沒有溫室效應(yīng)的出現(xiàn)，大氣逆輻射大大減弱，這樣讓天氣異常寒冷。

The control of haze has achieved very obvious results. The atmospheric environment has become very clear, especially the urban greenhouse effect, which has been greatly reduced. At the same temperature, without haze, the weather will be very cold because there is no greenhouse. With the appearance of the effect, the atmospheric back radiation is greatly reduced, which makes the weather extremely cold.

大氣環(huán)境我們國家治理好了，但是周邊的國家未必想像我們國家那樣鐵腕治理環(huán)境污染，如日本，日本位于我們國家的東邊，靠海生存的國家，本身國家資源短缺，靠海鮮、打魚出口為生，為了提升自己國家的國力，日本大力發(fā)展工業(yè)行業(yè)，很多工業(yè)廢棄物排到海里，造成日本暖流不能抵達我國沿海地區(qū)。

Our country has taken good care of the atmospheric environment, but neighboring countries may not want to control environmental pollution like ours. For example, Japan, Japan is located to the east of our country. A country that depends on the sea for survival has a shortage of resources in its own country. It depends on seafood and fish exports. In order to enhance its national strength, Japan vigorously develops its industrial industry. Many industrial wastes are discharged into the sea, causing the Japanese warm current to not reach the coastal areas of our country.

暖流對于內(nèi)陸的影響非常大，一旦暖流不能達到，就會造成天氣異常寒冷。

The warm current has a great impact on the inland. Once the warm current cannot reach it, it will cause the weather to be extremely cold.

 

還有一些國家，像印度、老撾、越南等經(jīng)濟不發(fā)達的國家，對大氣、海洋的環(huán)境不重視，大量排入廢棄水，流入到海洋中，據(jù)記載，北極和南極已經(jīng)出現(xiàn)了工業(yè)廢水污染物，充滿工業(yè)廢水的海水密度增大，海水密度越大，壓強越大，這樣阻礙北赤道暖流繼續(xù)北上，造成我們國家的天氣干燥、寒冷。

Some countries, such as India, Laos, Vietnam and other economically underdeveloped countries, do not pay attention to the environment of the atmosphere and ocean, and discharge a large amount of waste water into the ocean. According to records, industrial wastewater pollution has appeared in the Arctic and Antarctica. The density of seawater filled with industrial waste water increases. The greater the density of the seawater, the greater the pressure, which prevents the northern equatorial warm current from continuing northward, resulting in dry and cold weather in our country.

 

冬季刮西北風，來自西伯利亞的寒冷溪流，向內(nèi)陸飄逸，形成內(nèi)陸高壓，海洋的海水比熱大，冬季散熱慢，形成低壓帶，這樣阻礙了東南季風向內(nèi)陸的移動，不能把海洋的暖濕氣流流向內(nèi)陸，從而造成冬季我們國家異常寒冷。

In winter, the northwest wind blows, and the cold stream from Siberia flows inland, forming an inland high pressure. The sea water in the ocean is larger than the heat, and the heat dissipation is slow in winter, forming a low pressure zone. The warm and humid air flows inland, causing our country to be extremely cold in winter.
