Is the winter solstice the southernmost point of direct sunlight?

During the winter solstice, the sun points directly at the southernmost point of the year and points directly at the Tropic of Capricorn (23 26). At this time, the daytime in all parts of the northern hemisphere is the shortest in a year, which was called "short day" or "short day" in ancient times. Mohe, the northernmost part of China, has only 7 hours of daylight saving time, and there will be extreme night (24 hours) in the Arctic Circle.

However, "it's not too late" and "it's too late to pay back." The solstice in winter is also the turning point of the sun. After this day, it will go back, so the winter solstice is also called "the birth of a day." From winter to the future, the position of direct sunlight on the ground gradually moves northward, and the days in the northern hemisphere increase day by day and the nights gradually shorten.

Extended data:

Although the winter solstice has the shortest day and the longest night, it is not the coldest time of the year because of the residual heat on the surface. Astronomically speaking, the "winter solstice" means that the severe winter is coming, not the coldest weather, but that from this day on, China will enter the cold season of "counting nine cold days", which is also commonly known as "entering nine".

As the saying goes, "hot in dog days, cold in March 9". The coldest March 9 refers to the third 9 days after the winter solstice, that is, the 19 to the 27th day after the winter solstice. At this time, it is also in the period of slight cold and severe cold, and the climate reaches the coldest value in the whole year.
