How low will the weather get? Is there a standard?

There are two key words in this question: degree and standard.

It is not so much "degree" as "amplitude", which is a professional term and also a commonly used term in meteorology.

Weather forecast: The temperature drop is expected to drop from several degrees (Celsius) to several degrees, and how many degrees?

For example, it was originally 22 degrees, and cold air struck, and it was predicted that the temperature would drop to 14 degrees, with a drop of 8 degrees Celsius.

Generally speaking, in winter, if cold air hits Chinese mainland, the temperature drops between 4 degrees and 10 degrees.

If the actual temperature drop is only four or five degrees, it can be described as slight, and it may just be weak cold air.

If it drops by ten degrees or even ten degrees, it must be hit by strong cold air or even super strong!

As for the formation and movement of cold air, it is due to the high pressure activity in winter.

"Standard"? ... what can I say? It can only be said that the general temperature drop is between four degrees and eight degrees, when cold air strikes.
