What is the Antarctic phenomenon in winter in China? What happens in the Arctic in summer? China also has four solar terms, the length of day and night and the length of shadow.

Our country is located in the northern hemisphere. Winter and summer are opposite in the northern and southern hemispheres, and spring and autumn are opposite.

Winter in China, summer in the southern hemisphere, and extreme days in the Antarctic. In summer in China, there will be extreme days in the Arctic.

Length of Day and Night: The vernal equinox and the autumnal equinox are the same in the world (including China, of course), both of which are 12 hour. On the solstice in summer, the days in China are longer than the nights, with the longest days and the shortest nights. On the solstice in winter, the nights in China are longer than the days, with the longest nights and the shortest days.

Shadow length: Generally speaking, the shadow length at noon on the vernal equinox is between summer solstice and winter solstice. In summer solstice, the length of noon shadow in the Tropic of Cancer and northern China is the shortest in a year, while in winter solstice, the length of noon shadow is the longest in all parts of China. In the area south of the Tropic of Cancer in China, the sun will shine directly twice, so the place with the shortest shadow length at noon is not on the summer solstice.
