In which city does the sun shine directly in the second summer of the solstice?

Summer solstice is one of the 24 solar terms, which occurs on June 2 1 or 22 of the Gregorian calendar every year. On the day of summer solstice, the sun moves to 90 degrees of the yellow meridian, and the position of the sun directly on the ground reaches the northernmost point 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.

Therefore, we can draw a conclusion that the coordinate of the direct point of the sun from summer to the sun is 23 degrees and 26 minutes north latitude, but the longitude is not fixed, depending on which place is twelve noon at that time.

The geographical significance of the direct point of the sun has three aspects:

1. The movement of the direct point of the sun causes the change of global heat distribution.

2. The seasonal movement of the direct point of the sun drives the north-south movement of the planetary system.

3. The seasonal movement of the direct point of the sun causes the change of the length of day and night and the height of the sun at noon.

For example, from summer to the sun, direct sunlight reaches the northernmost part of the year, and it is located in 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 area, the summer solstice is also the highest day of the year at noon. In Beijing, the daytime from summer solstice can be as long as 15 hours, and the sun is as high as 73 degrees and 32 minutes at noon. On this day, the northern hemisphere gets the most sunshine, almost twice as much as the southern hemisphere.
