Americans are good at making movies, and they are also very good at making movies, and the movies they make are not only loved by their own people, but also popular all over the world.
But in a recent event in the United States, even the most experienced director could not shoot the effect in reality.
This was the tornado attack that occurred on the night of December 10, and as many as 30 more tornado swarms swept through the United States in one night, destroying countless farmland houses and causing at least 100 people to die in the tornado.
The tornado we have the impression is that it comes and goes quickly, although it is also a huge destructive force, but the scope of destruction is very small, and the tornado cluster that occurred in the United States this time is not only destructive, but also the path is also very long, about 400 kilometers. This led to a devastation wherever the tornado went.
The United States is a tornado-prone country, known as the country of tornadoes, with an average of 1250 tornadoes per year, which is reasonable to say that it has seen the world.
But when the United States announced the tornado situation to the outside world today, it described this tornado as the strongest tornado in history, and it seems that the United States, which has seen the world on the tornado, was also frightened in front of this tornado group, and in their own words, it was the strongest tornado in history.
Because tornadoes are a small-probability weather phenomenon, and their randomness is very strong, it is impossible to make accurate forecasts, so even countries with developed technology such as the United States are helpless when facing tornadoes.
The tornado in the United States also has a very strange place, every year from February to June is the high incidence of tornadoes, this time the tornado group was not born in that time period, but in December concentrated outbreak.
This is also caused by extreme climate change, after entering 2021, extreme climates appear frequently, in July this year, the temperature in the Middle East reached a terrifying high temperature of 70 degrees, at this temperature, many dishes do not use the pot, directly on the ground can be baked.
Also in July, there were two localized heavy rains, one in Germany and one in our country, both of which broke the region's historical record.
After entering December, the dry Taklamakan Desert, paved with a layer of silver, turned from golden yellow to snow white, and in December, the United States suffered the strongest tornado in history.
All kinds of signs can be seen that the extreme abnormal climate has indeed increased, is this a warning from nature to human beings, or is it that the extreme abnormal climate has begun, and this situation will increase in the future?
I think this question should be answered from three aspects:
1. Developed information
In the past 10 years, people spent their free time, generally using television and newspapers as a medium to obtain external information, due to the limited number of events and pages such as television and newspapers, their focus is generally on the world's big events, or in the face of some extreme climates, there will be no continuous reporting.
So at that time, some extreme climates did not leave a deep impression, but with the rise of self-media, people can have different choices according to their favorite focus, so this extreme climate can receive people's continuous attention.
2. The Year of La Niña
La Niña is a phenomenon that has a great impact on the Earth's climate, the main reason is that the wind in the eastern Pacific Ocean blows the seawater that absorbs the heat of the sun into the western Pacific Ocean, resulting in an increase in the temperature of the sea in the western Pacific Ocean, and the sea level also rises by about 60 centimeters, but the air pressure drops.
As the air pressure drops, the humid hot air rises, so the eastern Pacific Ocean is carried away because of the thermal energy, resulting in a decrease in temperature, the air pressure rises, and cold air from low altitudes such as Siberia will come to fill.
To this end, a global atmospheric circulation is formed, changing the local climate, leading to climate anomalies, extreme weather, because this year is in the La Niña event, so it is also called the La Niña Year.
The last time everyone was impressed by the year of La Niña was in 2008, that year there was an extreme climate, the south appeared in the north only in the cold rain weather, as for the tornado cluster in the United States, whether it received the impact of the La Niña event, it remains to be examined one step, but it is certain that the occurrence of the La Niña event will definitely have an abnormal climate.
3. Global warming
When it comes to global warming, it is a very grand systemic problem, and it is not something that ordinary people can say clearly.
But talk about your personal feelings, and some of what you've seen and heard. There used to be a small pond where I lived, and as I can remember, the small pond, although it froze every year, was not thick.
But listen to the adults at that time, when they were young, every winter, the pond would be covered with a thick layer of ice, and there was no problem for children to love to play on it, and sometimes adults had no problem going up.
In recent years, when I went back and walked by the small pond, I never froze, I thought it was just me going back, but when I asked people around, they all agreed that there was no ice.
From this, it can be seen that climate warming is a trend in recent decades, and global warming will cause the ice layers in the Arctic and Antarctic to melt, which will affect the global climate, so it is really difficult to say whether there will be more extreme climates in the future.
epilogue:
From an analytical point of view, the abnormal climate may increase, but there is a process, will not suddenly become harsh, and this year's abnormal climate may be caused by some natural extreme phenomena such as La Niña.
