Why is it so windy in Beijing?
The wind force forecast by the general meteorological department refers to the average wind force, such as the north wind 4 or 5. The public should not only pay attention to the average wind power, but also pay attention to the instantaneous wind speed, that is, the speed of airflow in a short time, such as gusts of 8 and 9, and the strong wind that appears in a short time will often bring disastrous consequences.

Matters needing attention when traveling in windy weather:
1. Try to avoid the "narrow tube effect" when walking and cycling: pay attention to the narrow passage between tall buildings when walking and 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.
2. Be careful not to stay under billboards and old trees for a long time: some billboards may collapse under strong winds 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.
