Why is the winter solstice different between the northern hemisphere and the southern hemisphere?

Because the sun shines directly on the tropic of Capricorn from the winter solstice in the northern hemisphere, it is summer in the southern hemisphere.

Winter solstice in the northern hemisphere and winter solstice in the southern hemisphere, but the seasons are different. The seasons in the northern and southern hemispheres are opposite, but it cannot be said that the winter solstice in the southern hemisphere is the summer solstice in the northern hemisphere. The correct expression is: during the winter solstice, it is winter in the northern hemisphere and summer in the southern hemisphere; During the summer solstice, the northern hemisphere is in summer and the southern hemisphere is in winter. The direct point of the sun from winter solstice is on the tropic of Capricorn, with the longest day and the shortest night in all parts of the southern hemisphere.

On February 2 1, 22 or 23 every year, the higher the latitude in the southern hemisphere, the longer the day and the shorter the night, and the Antarctic circle appears extremely daytime. In the Arctic Circle, there is a phenomenon of extreme night. The farther away from the tropic of Capricorn on the earth, the more inclined the sun's rays are, and the less solar heat is obtained. The winter solstice means that people have to experience the shortest day and the longest night in a year. After that, the days will gradually get longer.
