The windy weather in Jiangsu, the highest level 14. 14 What is the concept of gale?

A few days ago, there were strong winds and thunderstorms in many places in Jiangsu, especially strong winds. In many places, the wind reaches 32 to 39 meters per second. Even in Tongzhou District, Nantong, the wind reaches 14, and the wind speed exceeds 40 meters per second. 14 typhoon was so powerful that even the planes at Nantong airport were blown around, posing a great threat to people's lives. Let's look at the concept of gale 14.

14 the power of strong wind We learned the ballad of wind level when we were young, which mentioned that 10 strong wind could uproot trees, and at that time 12 strong wind was already a huge wave. Now let's talk about the concept of 14 gale. What kind of amazing state is it? In fact, the typhoon of 14 is really powerful, which is very rare in life. It is normal to roll people up and blow them away and uproot trees. Many times, we can overturn cars and blow down old houses, but we will be fine if we stay in our current reinforced concrete house. Just close the doors and windows.

Typhoon 14? Tian Ge? Let's take the typhoon that landed in Zhuhai on 20 17 as an example. Tian Ge? For example, what is the concept of 14 typhoon? Tian Ge? It landed in the south of Zhuhai at noon on August 23, with a central wind of 45 meters per second, reaching a typhoon level of 14. After the typhoon, we found that the trees that no one could support in the street were uprooted by the wind and collapsed, crushing a row of cars; The waves in Zhuhai and Shenzhen are as high as the sky, and the boardwalk and beach have been completely closed; Old trees planted in Shenzhen for many years were blown off or uprooted, and smaller trees and street signs were blown down in rows; Many trees in the administrative area of Hong Kong have been blown down, and scaffolding outside the building is crumbling.

The wind force per square meter is nearly 2000 kilograms. At present, the maximum wind power level we set is 17 typhoon, and the wind speed is 56.1-61.2m per second, which is rare in the world. 14 typhoon, the wind speed is 4 1.5-46. 1 m per second, it is easy to blow people away, push down the unstable fence and blow away billboards, flowerpots on the balcony and solar water heaters on the roof. According to the relevant measurement data, the strong wind of 14 acts on the plane perpendicular to the wind direction, and the pressure per square meter can reach 1700 to 2000 kilograms. That is to say, on a vertically flat rolled object, a strong wind of 14 can generate nearly 2000 kilograms of thrust per square meter, which is enough to blow away many cars, so it is not safe to hide in the car when the wind is too strong, so it is better to hide firmly.
