Speaking of gale, it is actually one of the major disastrous weather in China. Typhoon, strong convection, thunderstorm, tornado, strong cold air, cold wave and other weather will cause strong winds. Terrain? Narrow tube effect? It will increase the wind speed and make some areas windy. For example, Alashankou in northern Xinjiang, Taiwan Province Strait and other areas, in addition, people's changes to the natural environment will also affect the local wind speed, destroy the surface vegetation, and form a narrow wind tunnel effect between large high-rise buildings built in cities and towns. Wind disaster is closely related to wind direction and wind force. Wind direction refers to the direction in which the wind blows. For example, the wind from the north is called the north wind. Wind power usually refers to the wind power level, which is directly proportional to the wind speed. According to Beaufort wind power grade standard, it is generally divided into 12 grade.

1. What protective measures should be prepared in windy days?

Before the arrival of windy weather, doors and windows should be closed, and outdoor items susceptible to strong winds should be properly placed, such as clothes, glass or other sundries hanging on the balcony. Fix structures that are easily blown by the wind, such as hoardings, scaffolding and temporary structures. It is forbidden to use fire outdoors in windy weather. Neon lights and dangerous outdoor power supply should be cut off. Gas and natural gas valves connected to the outdoor should be closed to prevent outdoor fireworks. Stop outdoor activities, aerial work and water activities, and enter indoors as soon as possible, or enter the basement or semi-basement of concrete buildings to prevent wind.

When sailing at sea, it is necessary to keep abreast of the gale warning issued by the meteorological department. Before the strong wind comes, you must first find out whether your area is in a dangerous area where the strong wind will attack. If you try to stop water sports. Pay attention to the weather information and the latest trends of various media at any time, and move to relatively solid houses and buildings in advance when there is a strong wind warning. Leave dangerous houses and tin houses in simple rooms, and don't lean against the fence, lest the fence be blown down by strong wind and cause casualties! Agriculture and animal husbandry facilities and ships must be fixed in fixed ports. When the wind outside is getting stronger and stronger, stay away from the doors and windows and close all the doors in the back room. If I live in a building, I will stay in the back room of my arm and hide under a table or a solid object if necessary. In short, I should always be vigilant in the face of possible strong winds.

Finally, pay tribute to our police on duty!
