What's the difference between early winter and late winter?

The temperature is completely different.

Beginning of winter, one of the 24 solar terms, is also one of the traditional festivals of the Han nationality, as the end of the calendar and the beginning of the moon; The time point is between the Gregorian calendar165438+1October 7-8, that is, the sun is located at 225.

Midwinter: During the March 9th, because the ground received less heat from the sun, the heat emitted at night exceeded the heat absorbed during the day. At this time, the heat stored on the ground has been exhausted. Because the heat can't make ends meet, the ground temperature drops gradually and the weather is getting colder and colder.

If there is cold air at this time, the weather will become very cold. So "March 9" is the coldest weather. Deep winter means that the ice is long and the snow is several feet deep.
