Contrary to the northern hemisphere, after today, the nights and days in Antarctica are decreasing, and the days are gradually increasing. Midwinter Festival has become a common festival for Antarctic expedition members all over the world.
The summer solstice is the 10 of the 24 solar terms. Fighting means noon; The yellow meridian of the sun is 90 degrees; June 2 1~22 of Gregorian calendar. On the day of summer solstice, the position where the sun shines directly on the ground reaches the northernmost part of the year, almost directly on the tropic of cancer. At this time, the daylight hours in all parts of the northern hemisphere reach the longest in the whole year. For the Tropic of Cancer and its northern region, the summer solstice is also the highest day at noon in a year.
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. As the saying goes, "it's a hot day in dog days", and the real hot day is from mid-July to mid-August on the Gregorian calendar.
