Why is there a whistle when it is windy?

It is a physical phenomenon to make a "swish" sound when the wind blows. When the wind blows, the air will rub against the ground, leaves and buildings and make a sound.

The shape of the building is special, and the air will make a "special" sound like playing a flute when it passes quickly. The flute is played by someone, and it makes a rhythmic sound through the six sound holes in the middle and the two sound holes before and after.

When the wind blows, the chaotic sound made by tornadoes from countless irregularly distributed holes on the ground. Because it is the same as playing a flute, it sounds very similar. The difference is that when the wind blows, the sound is called growling and growling, which is also called devil may cry and wolf howl.

In windy weather, people who need to go out must take corresponding protective measures, especially when walking and cycling need to pass through narrow passages, or when passing through billboards and old trees, they should pay attention to avoid danger. Matters needing attention in windy weather mainly include the following points:

1. Try to avoid the "narrow tube effect" when walking and cycling.

Pay attention to the long and narrow passages between tall buildings when walking or cycling. Because the narrow passage will form a "narrow tube effect", the wind in the passage will increase, which will bring certain danger to pedestrians.

Be careful not to stay in billboards and old trees for a long time.

Some billboards may collapse under the strong wind because they are not installed firmly; However, some ancient trees have died, and the foundation is not firm. In windy weather, they may break, posing a danger to pedestrians.

3. Pay attention to the safety of light vehicles.

Because of its light weight, light vehicles may be lifted by strong winds when driving at high speed. You should put some heavy things on the light car or drive slowly.
