2. Wind energy blows sailboats to help people walk. Especially in ancient times, transportation mainly depended on ships. In Difficult Travel, Li Bai wrote: "One day, I will ride the wind and waves, and set my cloudy sail straight and bridge the deep, deep sea." This poem.
The wind will blow away the dark clouds and bring us sunshine. When dark clouds block the sun, it is the wind that drives them away and makes the sun spread all over the earth again.
The ancients used windmills to water crops.
In hot summer, the wind brings us coolness.
6. At present, people have learned to use wind turbines to generate electricity. This is pollution-free, clean and renewable energy.
7. Wind blowing clouds can promote the exchange of dry cold air and warm and humid air, mix and balance a wide range of heat and water vapor, and adjust the temperature and humidity of the air. This is what the ancients said: "Yun Teng is rainy, and dew is frosty". Wind energy sends clouds and rain to far places, so that the water cycle on the earth can be completed. Most parts of our country are affected by monsoon. In summer, the warm and humid air flow from the ocean brings abundant rainfall.
8. The northeast trade wind aroused strong seawater flow and formed a warm current, which brought a warm and humid climate to the coastal land flowing through.
Extended data:
Once the wind loses its temper, it is also harmful.
1. Strong winds blow up a lot of dust on the ground and drag it into the air, which makes the air turbid and the horizontal visibility is very low. The strong wind with dust destroyed buildings and public facilities, causing human and animal casualties.
Typhoon always brings all kinds of damage. Because of its sudden and destructive power, it is one of the most serious natural disasters in the world. The rainstorm and tsunami it brought were powerful and devastating.
3. It is a strong, small-scale air vortex, which is produced by the strong convective movement of air in extremely unstable weather. With the strong wind vortex of the funnel-shaped cloud column rotating at high speed, the wind speed near its center can reach 100 ms ~ 200 ms, and the maximum wind speed is 300ms, which is several times higher than the maximum wind speed near the typhoon center. It is extremely destructive.
If we don't care, what we need will be blown away. When the wind is angry, it will blow many things, even doors, windows and houses, blow crops and blow away flowers and fruits. Meng Haoran "but now I think of that night, that storm, I don't know how many flowers I folded." Du Fu said in "The Cottage is Blown by Autumn Wind" that "August and autumn are full of cool howling, and Sanhe grass is rolling in my house."
