Is it appropriate for the wind to whistle on the branches, the wind is level eight, and the branches

Maple characters, trees are broken wood, plus wind maple maple.

Wind classification.

The magnitude of the wind speed is often expressed in terms of the number of winds. The level of wind is determined based on the degree of influence of the wind on objects on the ground. In meteorology, it is generally divided into twelve levels according to the magnitude of the wind:

Level 0 wind is also called no wind.

Level 2 wind is called light breeze, and the leaves are slightly sounding, and the human face feels windy.

The level 4 wind is called the Japanese wind, and the twigs of the tree shake and can blow up dust and paper on the ground.

The level 6 wind is called a strong wind, the branches of large trees are shaking, the power lines are whirring, and it is difficult to walk with an umbrella.

Category 8 winds are called gales, and the branches of trees can be broken, and it is very difficult for people to walk in the wind.

Category 10 winds are called squalls, which are rare on land, and can uproot trees, causing serious damage to buildings.

Winds above level 12 are called typhoons or hurricanes, which are extremely destructive and rare on land.

In fact, in nature, the wind force can sometimes exceed force 12. The wind force at the center of a strong typhoon, or the wind force of a tornado, may be much stronger than that of a force 12, but it is relatively rare for winds above level 12 to be reached, and the number of winds is generally not specified.

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; If you hear a phrase such as "gust of 7", the gust refers to the wind speed fluctuates, and the wind force in this case refers to the wind force at the maximum.

The level 0 smoke column goes straight to the sky, and the level 1 green smoke deviates with the wind.

Level 2 breeze blows the face, level 3 leaves move the red flag.

Level 4 winds blow off pieces of paper, and level 5 small trees with leaves shake.

Level 6 is difficult to walk with an umbrella, and Level 7 is inconvenient to walk against the wind.

Level 8 winds blow tree branches and break branches, and level 9 roof tiles fly up.

Level 10 uprooting trees and toppling houses, 11, 12 rare on land.

This is a wind-level song when I was a child.,From what you said it should be 5 to 7 wind looks.,I hope it helps you.。

Yes, because he's deformed.

Because tree branches are elastic objects (within limits), the wind blows the bend of the branches and produces elastic deformation, and the elastic deformation of the object produces elastic force. This is the basics of physics.

The wind is formed due to ( air movement): the wind blows the branches, and the branches shake. Explain wind (which has energy and can be used to generate electricity).

Keep up with the trend of the times, green energy ......

The water waves are rippling, the water surface is the ripples, the meaning is not connected, and the epilogue cannot be used as a couplet.

The wind didn't move, the tree didn't move, it was the heart that moved.

From a relativistic point of view, you need to choose a frame of reference and start judging. If you choose the earth as the frame of reference, the branches and the wind are moving. If the wind is selected as the reference system, the wind does not move the branches.

Because you are alive, everything is moving.

The maple tree didn't move, it was the people who moved.

It's your heart that is beating and it's pure.

When I got up in the morning, the wind outside was blowing, like a typhoon of magnitude 8, beating the windows fiercely, the branches of the trees were broken, and the clothes drying on the balcony were gone.

I wish you progress in your studies o( o
