Phoenix City is in full swing: a natural disaster. While the Spring Festival banquet of various overseas Chinese associations in Phoenix City continues and they gather together happily, various media such as TV, radio, the Internet, and newspapers have released a series of unfortunate news, that is, tornadoes have invaded several states in the central and western regions. Later, some states did not deal with the aftermath in time, and were covered by blizzards. It is really sad that misfortunes never come singly. The natural disasters seen through TV cameras are indeed cruel. The picture is displayed in front of the audience. It is strong winds and hail attacks. Houses collapsed and vehicles were damaged. People had no choice but to flee, and some unfortunately lost their lives. It is truly tragic! In some areas, houses collapsed and were waiting to be cleaned up. Another blizzard hit. Thick white snow covered the ruins. This scene made the owner really want to cry. Tornadoes were reported to have hit several states in the Midwest, including Iowa, Minnesota, Kansas, Oklahoma, and parts of Illinois and Texas. Among them, Parkersburg in central Iowa, a town with a population of only 2,000, was directly swept by a tornado on Sunday, and people were trapped in collapsed buildings. Several nearby areas were also hit, with downed trees and power outages. Strong winds were also mixed with hail, killing at least seven people and injuring more than 50 people. In Minnesota, the disaster was also quite serious. The tornado destroyed nearly 200 houses, leaving them devastated, injuring more than 20 people, and a two-year-old child was reported dead. Hundreds of local residents were forced to evacuate due to gas leaks. As other places were hit by snowstorms again, it was no longer the cold that made the weather worse, but the strong winds that destroyed the snow cover, causing many natural disasters. I had heard the name "tornado" when I was a child in Vietnam, and witnessed it with my own eyes. At that time, I was playing in the countryside on the embankment. During the rainy season, the sky was dark, and a huge wind suddenly blew up, throwing a large amount of sand and dust into the sky, covering the entire earth. I heard the adults shouting: "Tornado! Run away!" Everyone ran into the house to hide. After a burst of noise, dust was flying everywhere, and there was no damage. So in the past, I always thought that tornadoes were nothing more than that and there was no need to be afraid. As I grow older and gain more knowledge, I realize from various news reports that powerful tornadoes can devastate humans and are truly terrifying. Whether the tornadoes I saw when I was a child has always been a question. It turns out that tornadoes are very strong winds, which are changes in natural gas phenomena. Some people say that a dragon in the sky absorbs water to form this huge force, and some people say that it is caused by the great power of a dragon that stirs up wind and rain. Looking through general scientific information, a tornado is a rapidly rotating and rising airflow around a strong low-pressure center, creating an oblique and hollow funnel-shaped airflow. It spins slightly in mid-air, kicking up sand and dust; or it stirs up waves on the water surface, which is not very powerful; the most serious is the activity of a strong and active cold front, which is strongly heated on the ground, causing the airflow to rise and move rapidly, bringing showers when it lands, and exerting its magical power of "raindrops from the sky". The speed is strong from more than 100 kilometers per hour or even up to 300 kilometers per hour, and can sweep away various objects. The destructive power is extremely fierce and extensive. The severe disasters in several provinces in the midwestern United States this time prove that the destructive power of their attacks cannot be ignored. According to various research reports, tornadoes occur everywhere, in Antarctica, eastern and south-central Asia, parts of Australia and New Zealand, various parts of Europe, southern Africa, central and eastern South America, and southern Canada. However, for some reason, the United States suffers more tornadoes than any other country and region. It is really a helpless natural disaster. sky! Why are there so many disasters in the world! People were complaining so much that some people asked the sky: Why are there so many disasters here? In recent years, natural disasters have become more and more frequent. Winds, floods, droughts, earthquakes, and tsunamis often cause heavy casualties, which is shocking. sky! Is there a master? Are there gods? Why do they bring disasters one after another? Make people suffer? "Man can conquer nature," textbooks once taught and encouraged students, but ruthless natural disasters have almost overturned this theory, and people are helpless when natural disasters come. The world is becoming more and more developed, and technology is becoming more and more advanced. We have landed on the moon, explored space, and gone on expeditions into the universe. However, the earth inhabited by humans is still troubled by disasters and cannot be spared. The United States is the world's superpower, but it is unable to stop strong winds. It is even more difficult for other vulnerable countries and people to fight against various natural disasters.
