Wind is not afraid of death. It always makes a mess of people's daily life. Before going out in the morning, my mother told me to wear gloves and a hat, but the wind blew my hat away, so I had to chase it against the cold wind. When I finally found my hat, the wind started its mischief again. It blew my hat so hard that I had to play hide-and-seek with it.

Wind power generation:
Wind is produced by atmospheric pressure difference. When the air pressure in two places is different, the air will flow and form the wind. The magnitude and direction of the wind depend on the magnitude and position of the air pressure difference.
The role of the wind:
Wind has a wide influence on human life. It can blow away air pollutants such as smog and dust and improve air quality; It can provide power and energy for human beings, such as wind power generation and navigation; It can adjust the climate, such as bringing rainfall and affecting the temperature.
Wind and culture:
Since ancient times, people's understanding and feelings about the wind have been closely linked with culture. In the traditional culture of China, wind has been endowed with many beautiful meanings, such as "spring breeze pride" and "gentle breeze and drizzle". At the same time, many ancient poems also have the figure of wind, such as Wang Zhihuan's "Loving at the Heron" and Li Bai's "The Beginning of Baidicheng".
Classification of wind:
According to the size of wind power, wind power can be divided into many types, such as breeze, breeze, gale, hurricane and so on. Different types of wind have different characteristics and influences. For example, the breeze is soft and comfortable, which can help people relax; Hurricane is a destructive natural disaster, which will bring serious losses to human beings.
Seasonal variation of wind:
In different seasons, the characteristics of wind will be different. For example, in summer, it is easy to form thermal circulation under high temperature and high humidity climate conditions, and weather phenomena such as typhoon and heat wave appear; It is easy to form a cold front to cross the border in cold weather in winter, which will bring weather phenomena such as cooling and frost.
In a word, wind is an indispensable part of nature.
