How to divide the wind level?

The classification of wind power levels is as follows:

1 0 wind: no wind, that is, no wind or weak wind, sunny weather, stable air pressure, straight smoke, and calm sea surface.

2. 1 wind: soft wind. At this time, the wind speed is very small, about 0.3~ 1.5 m/s, the weather is cool, the air pressure fluctuates slightly, the smoke can be blown up by the wind, and there are microwave fluctuations on the sea surface.

3.2 wind: light wind. At this time, the wind speed is about 1.6 ~ 3.3m/s ... The weather is more comfortable, the air pressure begins to fluctuate, the smoke will move with the wind, and small peaks begin to appear on the sea.

4. Level 3 wind: a breeze with a wind speed of about 3.4 ~ 5.4 m/s ... The weather is pleasant, the air pressure is stable, the smoke will sway with the wind, and the small peaks on the sea surface will start to break.

5, 4 wind: breeze, the wind speed is about 5.5~7.9 m/s ... The weather is more comfortable, the air pressure is more stable, dust can be blown up, and small waves on the sea surface begin to appear foam peaks.

6, 5 wind: strong wind, when the wind speed is about 8.0~ 10.7 m/s, the weather is cool, the air pressure begins to fluctuate, and some small things such as leaves can be blown, and foam peaks in the waves begin to appear.

7, 6 wind: strong wind. At this time, the wind speed is about 10.8~ 13.8 m/s, the weather is cool, the air pressure is stable, the wires begin to sound, and a drop of water begins to appear in the waves.

8, 7 wind: strong wind, at this time, the wind speed is about13.9 ~17.1m/s, the weather is cool, the air pressure begins to fluctuate, it will be more difficult to walk, and the sea surface will break the peak and start to foam into strips.

9, 8 wind: strong wind, when the wind speed is about 17.2~20.7 m/s, the weather is cool, the air pressure is stable, the branches can be broken, and the waves begin to roll and roar.

10, grade 9 wind: strong wind, when the wind speed is about 20.8~24.4 m/s, the weather is cool, and the air pressure begins to fluctuate, which can cause slight damage to some buildings and the waves begin to form huge waves.

1 1, 10 wind: strong wind. At this time, the wind speed is about 24.5~28.4 m/s, the weather is cool, the air pressure begins to fluctuate violently, trees and other items can be pulled up, and the waves begin to roll.

12, 1 1 wind:1/above is a strong typhoon. 1 1 Typhoon is set at 32.4~36.9 m/s.

Matters needing attention in typhoon days:

1. Stay away from the danger zone: If there are geological disasters such as landslides, mudslides and land subsidence in the living area, you must evacuate as soon as possible; People in high-rise buildings should be evacuated to the ground floor. Don't walk on rivers, lakes, seawalls or bridges. Don't go swimming at the beach. People who are swimming should go ashore at once. Stay away from the construction site as far as possible, and pay attention to avoid falling objects when passing under tall buildings.

2. Try not to go out when the typhoon comes: If you have to go out, please pay attention to stay away from windward doors and windows, avoid the rain and stay under the big tree. When driving in windy weather, you should drive at a low speed or stop temporarily, and stop away from buildings, billboards, dead trees, etc. In addition, don't go out by bike during a typhoon.

3. Go slow or stop: on a typhoon day, the line of sight is not good, and "slow" and "stable" are the most important. Don't blindly overtake in parallel, pay close attention to information such as road water accumulation, traffic congestion and interruption, and pay attention to pedestrians and vehicles around to ensure driving safety. When the traffic is blocked, you should obey the command of the traffic police and accept the guidance in time.
