Wind has both magnitude and direction, so wind forecasting includes both wind speed and direction. The magnitude of the wind speed is commonly used.

to represent. The level of the wind is determined based on the degree of influence of the wind on objects on the ground. In terms of meteorology, it is generally divided into 17 levels according to the magnitude of the wind.

In weather forecasting, it is common to hear terms such as "north wind force 4 to 5", in which case the wind refers to the average wind force; As heard "gusts."

Category 7", the gust of wind refers to the wind speed fluctuates, and the wind force in this case refers to the wind force when it is high.

In fact, in nature, the wind force can sometimes exceed force 12. Like the wind in the center of a strong typhoon, or a tornado.

The wind force may be much greater than that of level 12, but winds above level 12 are relatively rare, and the number of levels is generally not specified.

Hello, a wind speed of 7 meters per second is equivalent to a level 4 Japanese wind. See the following figure for details:

Category 6 winds. 1kilometre (km) km = mile.

Wind level 6: Overview of strong winds.

The branches of the trees on land are shaking, the wires are whirring, and it is difficult to lift an umbrella.

Fishing boats on the coast have doubled their sails and should be aware of the dangers of fishing.

Considerable wind speed (m s).

Wind Level 7: Overview of the Wind.

The trees on land are shaking, and it is inconvenient to walk in the wind.

Coastal fishing boats stop in the harbor and go to anchor overseas.

Considerable wind speed (m s).

Wind level 8: Overview of high winds.

Branches on land are broken, and walking in the wind feels very resistant.

Ships on the coast and near the port are not allowed to stay.

Considerable wind speed (m s).

1 kilometre (km) kilometer = mile mile.

Translated, 25 mph is about 40 km/h, which is a force 6 wind.

The wind scale is used to indicate the magnitude of the wind**, which is usually divided according to the wind speed. Wind speed refers to the distance that air travels per unit of time, usually measured in meters and seconds. Here is a table of wind ratings:

Category 0 wind: the wind speed is meter seconds, the smoke is straight up, and the water surface has no effect.

Category 1 wind: The wind speed is meters and seconds, the smoke indicates the wind direction, and the water surface ripples.

Category 2 wind: the wind speed is meters and seconds, the leaves and twigs are constantly waving, and the flags are blown.

Category 3 wind: The wind speed is meters and seconds, and the leaves and twigs of the trees are constantly swinging, and the flag begins to roll.

Category 4 wind: The wind speed is meters and seconds, and the twigs of the trees shake and can blow dust and paper from the ground.

Category 5 winds: The wind speed is meter seconds, the leafy trees are swaying, and there are small waves on the water surface inland.

Category 6 wind: The wind speed is meters and seconds, the branches of large trees are shaking, and the waves on the water surface are magnificent.

Category 7 wind: The wind speed is meters and seconds, the whole tree is shaking, the heads of pedestrians stand upright, and the water surface turns white waves. Tuanhu.

Category 8 wind: The wind speed is meters and seconds, the branches are broken, and people feel very resistant to the wind.

Category 9 wind: The wind speed is meters and seconds, uprooting trees, causing damage to the glass curtain walls and decorations of high-rise buildings.

Category 10 wind: The wind speed is meters and seconds, which is seriously destructive, causing serious damage to buildings and general destruction of houses.

Wind above level 11: The wind speed is greater than meter second, the destructive force is extremely large, and the building will be severely damaged or even destroyed.

According to the wind classification standard of the International Society of Maritime and Land Aerology, the wind force is divided into 12 levels, and the wind speed range of each level is:

Wind force level 0: no wind, wind speed less than 1 knot or less than meter second;

Wind force level 1: soft wind, wind speed 1-3 knots or meter second;

Wind force level 2: light wind, wind speed 4-6 knots or meter seconds;

Wind force level 3: light wind, wind speed 7-10 knots or m seconds;

Wind force level 4: Japanese wind, wind speed 11-16 knots or meter second Hui group;

Wind force level 5: clean wind, wind speed 17-21 knots or meter second;

Wind force 6: strong wind, wind speed 22-27 knots or meters and seconds;

Wind force 7: strong wind, wind speed 28-33 knots or m second;

Wind force 8: gale, wind speed 34-40 knots or meter second;

Wind force 9: squall, wind speed 41-47 knots or Yoneno Bixun seconds;

Wind force 10: storm, wind speed 48-55 knots or meter second;

Wind force 11: typhoon, wind speed 56-63 knots or m seconds;

Wind force 12: Hurricane, wind speed greater than 63 knots or greater than meter seconds.

Therefore, converting the wind speed of 24 kilometers per hour to meter seconds, we get:

24 kmh = 24,000 m h 3,600 seconds Hour = m second.

From this, it can be seen that a wind speed of 24 kilometers per hour is equivalent to a force 6 wind.

There are 13 levels of wind, and level 0 refers to the wind speed of 0 to meters per second, which is characterized by a calm wind and smoke straight up. Level 1 refers to the wind speed per second to meters, characterized by soft wind, and smoke energy indicates direction. Level 2 refers to wind speeds per second to meters, characterized by light winds and slight sound from tree branches.

Level 3 refers to the wind speed per second is to meters, characterized by a light breeze and a flag. Category 4 refers to wind speeds of up to meters per second, characterized by moderate winds, where ground dust and paper can be blown up. Level 5 refers to a wind speed of 8 to meters per second, characterized by a clear wind, small trees shaking, and small waves on the water surface.

Level 6 refers to wind speeds of up to meters per second, characterized by strong winds, large tree branches shaking, and power lines whirring. Category 7 refers to wind speeds of up to meters per second, characterized by strong winds, shaking of the whole tree, and difficulty walking in the wind. Category 8 refers to wind speeds of up to meters per second, characterized by high winds, broken tree branches, and great resistance on foot.

Grade 9 refers to winds of up to meters per second, which is characterized by strong winds, which can blow down small roofs and make it difficult for steamboats to navigate. Grade 10 refers to wind speeds of up to meters per second, characterized by strong winds, rare on land, and can blow down buildings. Category 11 refers to the wind speed of meters per second, which is characterized by stormy winds, which are very destructive and extremely dangerous for steamboats.

Category 12 refers to wind speeds greater than meters per second, characterized by hurricanes, monstrous waves, and extremely destructive power.

Converted to kilometers per hour, kilometers per hour, so the wind speed of different levels is about 0 to kilometers per hour.

Level 0 Calm Wind Wind speed: 0 seconds, quiet, smoke straight up.

Grade soft wind Wind speed: seconds, smoke energy indicates wind direction.

Light wind speed in seconds, with a slight sound in the leaves.

Level Breeze The wind speed is seconds, and the leaves and twigs are shaking.

Level Japanese Wind Wind speed seconds, dust and shredded paper raised, small tree branches shaking level Clear wind Wind speed seconds, small branches shaking, small waves on the water surface Strong wind Wind speed seconds, large tree branches shaking, power lines whirring with sound level Wind speed Wind speed seconds, whole tree shaking, walking against the wind feels difficult High wind Wind speed seconds, tree branches breaking, resistance to travel against the wind is very high Gale Wind speed seconds, slight building damage occurs.

Wind speed refers to the rate of movement of air relative to a fixed place on the earth, and the common unit is m s, 1m s = km h. There is no grade of wind speed, only wind power has a grade, and wind speed is the basis for the classification of wind power. Generally speaking, the higher the wind speed and the higher the wind level, the more destructive the wind is.

Wind speed is one of the main parameters in climatological research.

Wind Scale.

Different wind speeds are different.

How many kilometers per hour is the speed of the wind Let the speed of the aircraft be x and the wind speed is y, then x+y=a, x-y=b, solve the equation, and obtain, y, that is, wind speed = (a-b) 2,

Let the speed of the aircraft be x and the wind speed be y, then x+y=a, x-y=b, solve the equation, and obtain, y, that is, wind speed = (a-b) 2,
