How to determine what wind level it is now?

It can be judged according to the following standards:

The size of wind speed is often expressed by several levels of wind. The level of wind is determined based on how much the wind affects objects on the ground. Meteorologically, winds are generally divided into twelve levels according to their strength.

In fact, in nature, the wind force sometimes exceeds level 12. For example, the wind force at the center of a strong typhoon or a tornado may be much stronger than level 12. However, strong winds above level 12 are relatively rare, and generally the level is not specified.

In weather forecasts, we often hear terms such as "North wind level 4 to 5", and the wind force referred to at this time is the average wind force; for example, we hear terms such as "gust level 7" In terms of wind gust, it refers to the wind speed that changes from high to low, and the wind force at this time refers to the maximum wind force.
