Thousands of flights on the east coast of the United States were forced to cancel. How violent is the storm?

? This stormy weather is a terrible extreme weather. Why do you say that? The place where the storm happened is just like the bridge in many sci-fi movies, which is the weather accompanied by strong winds or heavy precipitation, such as tornadoes, dragons absorbing water, typhoons and so on.

? Why are thousands of flights on the east coast of the United States cancelled, but there is no way to take off and land? The weather conditions are really bad, just like when a tornado appears, it is usually accompanied by thunderstorms and hail. The air pressure in the center of the tornado is very low and the wind is very strong, which is destructive. The maximum horizontal distance of a tornado can reach about 1 1,000 m, which can easily uproot trees, causing great damage to vehicles and houses, and sometimes causing considerable casualties.

For example, 1999, there was a storm in Oklahoma. After measurement by professional researchers, it is found that the fastest wind speed has reached 142.5 meters per second, or more popularly, 5 13 kilometers per hour. This speed is easy to understand. Everywhere I went, only broken walls and Spanish storms were left, almost like the end of the world. Large areas of rain and snow occurred in various parts of Spain, and land traffic was blocked. Even the water level of many rivers rises, and many lands are flooded. Residents' life and work must not be forced to stop, and their lives and health are also greatly threatened.

? So how do people deal with stormy weather? First of all, people in stormy areas must avoid going out. It is best to stay at home, close doors and windows and take protective measures. Pay attention to the weather forecast and make preparations in advance. You can prepare some emergency supplies and medical supplies at home, and reinforce your own doors, windows and houses when necessary.
