Is the dawn early or late in winter?

The earth passes through the direction of rotation from day to night, which is the "dark line" and from night to day, which is the "morning line". 24 hours a day, seasonal changes are also the result of the movement of the direct point of the sun. At sunrise and sunset, the length of the day and the length of the night also change, and so does the termination line perpendicular to it.

When the sun shines directly in the northern hemisphere, it is our summer, and the morning line it forms is mostly red. At this time, the longer the day, the longer the day, so the extreme day phenomenon appeared in the Arctic.

It's winter in the northern hemisphere, so direct sunlight will shine in the southern hemisphere. The nights in the northern hemisphere are always shorter than the days. Because of this, dawn is late and darkness is early in winter.

Climatic characteristics in winter:

In some areas of southern China, there is always warm weather like spring in winter solstice and light snow solar terms, so that some fruit trees mistakenly think that spring is coming and bloom for the second time, which is the so-called "warm in August, warm in September and sunny in October"

In the dead of winter, it is usually not very cold before the so-called "Sanjiu Cold" and "Sanjiu Cold". Starting from the winter solstice, every "nine days" counts as a "nine", the first nine days are called "one nine" and the last nine days are called "two nine".

By analogy, the coldest period of the year is "three or nine days". From the beginning of the winter solstice solar term, it began to enter the "three or nine days." Strong cold air frequently goes south, the temperature drops suddenly and the weather is cold. Therefore, the solstice winter is really cold winter.
