Why is this year s snow brush sales so much larger than in previous years?

People born in the noon of dogs are active, sharp-eyed, and have a keen sense of smell, and are hunter-type characters, ambitious in their careers, able to see business opportunities everywhere in society, and have the courage to obtain goals, so they are busy with their careers and social interactions, and will not stay at home, but they are very loving and loyal to their wives. If it is a woman, she is sensitive to love, straightforward, and charming, so most of them marry early, and they will be happy. However, they also do not like to stay at home, and will continue to work before marriage, and belong to commuters or people who have a family business.

People who belong to the dog and are born at night give full play to their loyalty, whether they are to their bosses, teachers, elders, etc., they are loyal and will not apostatize, from the country to the small friends, they can be loyal to the end, and after becoming friends, they can maintain lifelong friendships. This kind of man has a peaceful temperament, is loyal to all affairs, is loyal to his family, will think that family and friendship are more important than money, will love his wife and children, and is also a good man. If it is a woman, she is sleek, easy to be friends with others, and will also make colleagues and classmates have a good impression, so the proportion of colleagues getting married is more.

This year, there is a lot of snowfall across the country, and the temperature is colder than usual, and the cold is not a very general thing to tell, and sometimes it is affected by cold air.

The main reason for the unusually cold weather in the Northern Hemisphere this winter is the strong negative phase of the Arctic Oscillation (AO). The Arctic Oscillation is a seesaw phenomenon in which the mid-latitude and high-latitude air pressure in the Northern Hemisphere rises and falls. The negative phase of the Arctic Oscillation means that the air pressure over the Arctic and Iceland (high latitudes) is high, which in turn releases pressure to the southern mid-latitudes.

In the Arctic, which has been in a state of low pressure in previous years, high pressure (i.e., negative phase) has occurred, resulting in easterly or northeasterly winds blowing near the surface in the southern region (mid-latitudes). These winds blow from the cold Arctic land or the Arctic Ocean, bringing a powerful cold snap to the Northern Hemisphere.

In the north, Shanxi and Inner Mongolia, two major coal-producing provinces and regions, signed the "Medium and Long-term Coal Contract" respectively to alleviate the shortage of electricity. In Guangdong, the normal life of some large people has been greatly affected by the lack of electricity. Speaking of which, winter is not the peak of the year for electricity consumption, and this year's winter is no colder than usual

, the crystal snowflakes in the sky are as big as goose feathers, and the whole world is dressed in silver.

This year's blizzard is an anomalous climate, and it is likely to be a La Niña!

Like other countries, some are also experiencing heavy snowfall, while others are flooding!

See below. We are in a La Niña state this year, that is, the sea surface temperature in the eastern equatorial Pacific is lower than normal, and the impact of this phenomenon on China's climate is very obvious. It's going to have a cold winter, so we can see that this cold winter is coming this year.

Lanina is just one of the reasons, and the other causes of heavy snow are as follows:

Since 2008, the Asian high pressure is very active, and the cold air mass has been formed to affect our country in the south, resulting in a wide range of windy cooling weather, but because the warm air mass in the south this year is also very active, a large number of warm and humid air currents from the Pacific Ocean and the Indian Ocean frequently visit the southern region, when the strong cold air mass from Siberia, Mongolia quickly moves south to the southern region, and meets with the warm and humid air mass, the cold, warm two just combined. Affected by the combination of these two airflows, there has been a lot of rain and snow in recent times, especially in the Yangtze River basin, and the weather has been maintained at low temperatures for a long time. If there is only a strong cold air mass, and there is no large amount of water vapor provided by the warm and humid air mass, there will only be strong winds and cooling weather in the south; If there is only a large amount of water vapor provided by the warm and humid air mass, and no cold air mass is present, there is no catastrophic weather at all.

And when both are in place, disaster strikes.

At the same time, when China was hit hard by the snow disaster, the central United States experienced a sharp cooling of 20 degrees Celsius, and blizzards were infested from time to time (; 10mm of snow suddenly fell in Central Asia, which had not snowed for a century, setting a new record for 100 years without snow in Baghdad. Western Europe 07 summer floods, Britain and France suffered huge losses (2007 summer), since the beginning of winter, the temperature in the northern edge of Russia has hit a new low, once reaching -50 degrees Celsius......La Niña is not over, and the situation is still serious.

The earth's climate is deteriorating, the ozone layer is polluted, the Arctic glaciers are melting at an accelerated rate, and the impact of the cosmic environment on the earth is becoming more and more obvious.

So, later in the summer it will be hotter and the winter will be colder.

**Original article online "Why is it so cold this winter").

Q: Why is it so cold this winter?

Answer: Circulation anomaly, "La Niña".

Why is it continuing to be cold this winter?

It is believed that this is related to the special orientation of atmospheric circulation and La Niña events.

The anomaly of atmospheric circulation makes the cold air accumulated in the Arctic all year round have the opportunity and conditions to move southward, resulting in frequent cold air invasion in China and even our province, bringing cold waves and cooling.

In addition, meteorological experts also say that this year is a moderately strong La Niña year. La Niña refers to the persistently unusually cold sea surface temperature in the eastern and central equatorial Pacific Ocean, often alternating with El Niño. When the La Niña phenomenon occurs, our country is prone to cold winters and hot summers.

Contrary to the high temperatures brought by the El Niño phenomenon, the La Niña phenomenon tends to bring low temperatures, which is the reason for the persistently low temperatures in our province.

You have to ask the question of the Siberian cold snap.
