刚进入2021，为什么天气异常的冷，超过了以往任何冬天的低温水平

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

元旦刚过，北方的气温低至零下11摄氏度，这是什么概念，先描述下症状：

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，脸上如刀割一般，顿时知道什么是威风凛凛。

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

2、手脚不敢露出，不然可能瞬间被冻僵。

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

3、哈尔滨的温度零下30摄氏度，几乎泼水成冰，人们不能出去购物，一不小心，呼出的气体直接成冰棍。

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温？What causes such low temperature under analysis?

虽然，这样的极端气温，影响了人们的生活，但是，确实一种好现象。

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

 

 

 

国家对于污染问题，大气污染治理极其重视，对于各种工业生成，进行了遏制，比如，印刷行业，废旧气体排出的冶铁企业，进行了限制或者定时开工，目的就是减轻对大气的污染，提倡“绿水青山，金山银山”。

 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".

雾霾的治理已经取得了非常明显的成效，大气环境变得非常的清晰，尤其城市温室效应，大大减弱，同样的温度，在无雾霾的情况下，天气就会非常的寒冷，因为没有温室效应的出现，大气逆辐射大大减弱，这样让天气异常寒冷。

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.

大气环境我们国家治理好了，但是周边的国家未必想像我们国家那样铁腕治理环境污染，如日本，日本位于我们国家的东边，靠海生存的国家，本身国家资源短缺，靠海鲜、打鱼出口为生，为了提升自己国家的国力，日本大力发展工业行业，很多工业废弃物排到海里，造成日本暖流不能抵达我国沿海地区。

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.

暖流对于内陆的影响非常大，一旦暖流不能达到，就会造成天气异常寒冷。

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.

 

还有一些国家，像印度、老挝、越南等经济不发达的国家，对大气、海洋的环境不重视，大量排入废弃水，流入到海洋中，据记载，北极和南极已经出现了工业废水污染物，充满工业废水的海水密度增大，海水密度越大，压强越大，这样阻碍北赤道暖流继续北上，造成我们国家的天气干燥、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.

 

冬季刮西北风，来自西伯利亚的寒冷溪流，向内陆飘逸，形成内陆高压，海洋的海水比热大，冬季散热慢，形成低压带，这样阻碍了东南季风向内陆的移动，不能把海洋的暖湿气流流向内陆，从而造成冬季我们国家异常寒冷。

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.
