A snowstorm swept across the northeastern United States. Why are there so many extreme weather in America?

Blizzard swept across the northeastern United States, and why extreme weather frequently appeared in the United States became a hot topic. Extreme weather often occurs in the United States for the following reasons.

First of all, the United States has a vast territory, complex terrain and very different climate. The whole country is divided into five climatic zones: the temperate zone along the northeast coast, the tropical zone in Southeast Asia, the continental climate zone in the central plain, the arid climate zone in the western plateau and the coastal maritime climate zone. Pacific coast. Among them, the northeast coastal areas are cold in winter and prone to snowstorms. Forest fires are prone to occur in the arid climate area of the western plateau; In spring and summer, tornadoes are prone to occur in the central and western regions. Hurricanes often occur in the coastal areas of Mexico.

The snowstorm in America in the last century left a deep impression on people. At that time, the snowstorm lasted for a week, which made many Americans lose power, heating and transportation for days or even weeks. A week after the snowstorm, many families still have no heating, water, electricity and food. People have to stay at home or in the office, or even get stuck on the road, which is life-threatening. Stop providing food, milk, newspapers, etc. Distribute some food and close the school for a few weeks. Massachusetts, Ohio, Michigan and other States announced their entry? A state of emergency, and mobilize the National Guard to rescue vehicles and personnel trapped on the expressway. According to the records, the snowstorm of 1978 lost 500 million dollars in Massachusetts alone.

Finally, poor engineering quality is also one of the factors that affect the expansion of extreme weather. Large-scale infrastructure should enhance its ability to resist natural disasters. The main reason why New Orleans was hit by a hurricane was the destruction of the flood control dam. American public opinion believes that this is due to the reduction of flood control funds, which leads to the dilapidated dam. In addition, the seawall in New Orleans is a bean curd project. It is reported that the damage of the flood control dam was found at the root, resulting in 80% of the city being flooded. China's infrastructure construction is large in scale and fast, and it has made remarkable achievements in the world. But at the same time, we should also attach great importance to improving the design level, engineering quality and management ability, and enhance the ability to resist natural disasters.
