What is the reason for the strong wind in spring?

In spring, the cold air in the north is still very strong, and it keeps going south, and the surface is heated by light, which warms the air near the surface and forms strong convection with the cold air at high altitude.

Because the high-altitude wind is usually much stronger than the ground wind, in the up-and-down convection movement, the high-altitude wind speed is transmitted to the ground, thus forming an obvious gust.

Matters needing attention in windy spring

First, pay attention to fire prevention.

The wind is strong and the things are dry, and the fire danger is great. Pay attention to fire safety in windy weather. It is necessary to strengthen the cleaning of flammable materials to keep them away from fire sources; It is forbidden to burn garbage and straw outdoors to avoid fire accidents; Always check whether there are fire hazards in the surrounding environment where you live. Once found, eliminate it in time.

The second is to avoid the "narrow tube effect".

When walking or riding a bike, take less long and narrow passages between high-rise buildings, because the long and narrow passages will form a "narrow pipe effect" and the wind in the passages will increase, which will bring certain dangers to pedestrians.

Third, be careful of falling objects.

Some billboards may collapse under the strong wind because they are not installed firmly; Moreover, some old tree trunks have died and the foundation is not firm, which may break in windy weather, posing danger to pedestrians; Air conditioners, flower pots and other sundries stored at high altitude are all high-risk items that cause crush accidents, and some aging building materials such as glass curtain walls and exterior wall tiles also have hidden dangers of falling off and hurting people.
