As shown in the figure below:

Due to differences in wind speed, direction and humidity, many types of wind will be generated. Gusts, gales, gales, squalls, storms and hurricanes are common types of winds with Beaufort wind strengths of seven, eight, nine, ten, eleven and twelve respectively.

Gusts: When the flow speed of the air increases and decreases, the wind will become suddenly strong and sometimes soft, and it will feel like gusts of wind blowing on people's bodies. This is what is recognized in life as gusts of wind.

In meteorology, wind speed usually refers to the average situation within 2 minutes, and the wind speed varies from time to time. The gust usually refers to the maximum instantaneous wind speed during this period. If the weather forecast predicts that today’s wind will be level 4-5 and gust level 6, that means the average wind will be level 4-5 and the maximum instantaneous wind will be level 6.

The role of wind

Positive

Wind is one of the environmental factors in agricultural production. Moderate wind speed plays an important role in improving farmland environmental conditions. Near-surface heat exchange, farmland evapotranspiration, and transport processes of carbon dioxide and oxygen in the air accelerate or intensify as wind speed increases. Wind can spread plant pollen and seeds, helping plants to pollinate and reproduce. Wind energy is a widely distributed and inexhaustible energy source.

The prevailing monsoon in China is beneficial to crop growth. In the Inner Mongolia Plateau, Northeast Plateau, Southeast Coast and inland mountains, there are abundant wind energy resources that can be developed and utilized as energy.

Negative

Wind can also have a negative effect on agriculture. It can spread pathogens and spread plant diseases. High-altitude winds are the meteorological conditions for pests such as armyworms, rice planthoppers, rice leaf rollers, and migratory locusts to migrate over long distances. Strong winds can cause mechanical scratches on leaves, lodging of crops, broken trees, and falling flowers and fruits, thus affecting yields. Strong winds also cause soil erosion, sand dune movement, and damage to farmland. Blind reclamation in arid areas will cause land desertification due to wind.
