In winter solstice, where does the sun shine directly on the earth?

On the solstice of winter, the sun shines directly on the tropic of Capricorn.

1, winter solstice is one of the 24 solar terms, with the shortest day and the longest night. If 12 noon is the boundary, the length of day and night is equal. From winter to sunrise, the sun shines directly on the Tropic of Capricorn. The sun is most inclined to the northern hemisphere, with the shortest day and the longest night, while the southern hemisphere is the opposite, with the longest day and the shortest night. The extreme night phenomenon appears in the Arctic Circle, and the extreme day phenomenon appears in the Antarctic Circle.

2. As an important node of the 24 solar terms in China, the winter solstice marks the official start of winter in the northern hemisphere. On the solstice of winter, the sun shines directly on the Tropic of Capricorn, which is a virtual line around the earth and located at the southern end of the earth. The winter solstice is so named because it is the day when the northern hemisphere receives the least solar radiation energy.

At this time, the position of the sun is the lowest, which makes the day the shortest and the night the longest. Nevertheless, the winter solstice does not mean that the weather will become particularly cold, because cold air activities usually begin before the winter solstice. On the solstice of winter, people will carry out many traditional activities. In China, the solstice in winter is an important festival, and people will eat traditional foods such as jiaozi and glutinous rice balls to celebrate.

The tropic of Capricorn, where the sun shines directly on the earth, has the following effects:

1. When the sun shines directly on the tropic of Capricorn, it will have a series of influences on the earth's climate, astronomy, biology and human life. First of all, from the climate point of view, the tropic of Capricorn with direct sunlight marks the official start of winter in the northern hemisphere. At this time, the solar radiation energy received by the northern hemisphere decreases, resulting in a drop in temperature and cold weather.

2. At the same time, the southern hemisphere began to enter summer, the temperature rose and the weather became warmer. This seasonal change will affect the global climate pattern and lead to climate anomalies in some areas. Secondly, from the astronomical point of view, when the sun directly hits the Tropic of Capricorn, the position of the earth is at the southernmost point relative to the sun, which makes the night in the northern hemisphere the longest and the day the shortest.

At the same time, the southern hemisphere has the longest day and the shortest night. This astronomical phenomenon also has a certain influence on the rotation and revolution speed of the earth. In addition, the winter solstice is also an important solar term for living things. Many animals began to hibernate to adapt to the cold climate. Plants will also go into a dormant state and stop growing.
