Introduction to summer solstice:

The summer solstice is the 10 of the 24 solar terms. The solstice in summer is the turning point of the sun's northward movement. After the summer solstice, the direct point of the sun began to move south from the Tropic of Cancer, and the days in the northern hemisphere began to shorten gradually.

For China, which is located in the north of the Tropic of Cancer, after the summer solstice, the height of the noon sun begins to decrease day by day; For China, which is located in the south of the Tropic of Cancer, after the summer solstice, the height of the sun returned to the south at noon, and it began to decrease day by day after the sun shone again.

After the summer solstice, although the direct point of the sun began to move south from the Tropic of Cancer, the days in the northern hemisphere began to shorten gradually, but the temperature will continue to rise for a while, because the heat radiated by the sun to the ground is still more than the heat radiated from the ground to the air, so there is a saying that the summer solstice is not too hot.

From summer to the sun, the sun directly reaches the northernmost part of the year, and the daylight time in all parts of the northern hemisphere reaches the longest in the year. During this period, the temperature in most parts of China was high, the sunshine was sufficient, the crops grew rapidly, and the physiological and ecological water demand was high.

"Summer solstice" is the starting point of midsummer. Although it has not reached the hottest day of the year, it is not far from "health". Starting from "midsummer", after three "three-night days", it entered the hottest dog days of the year. The so-called "several heads fell off in the middle of summer" is characterized by high temperature, high humidity and occasional thunderstorms from summer to the future.

On the day of summer solstice, the sun shines almost directly on the Tropic of Cancer, and absolutely (almost) directly at noon, and there will be a spectacle of "standing without a shadow" near the Tropic of Cancer. The phenomenon of "standing without shadow" only exists in the area south of the Tropic of Cancer, and the sun shines vertically on the ground twice a year.
