The light map analysis of summer solstice in the northern hemisphere, is it appropriate to share a room from summer solstice to sun in 2020?

Light analysis chart of summer solstice in the northern hemisphere!

This is the sunshine map of the earth around the summer solstice. The meridian of half the earth divides the earth into 12 parts, and a day is 24 hours, so the time difference between every two meridians is 1 hour (because it is half the earth).

For example, if you are at A in the picture (the same is true at B or C, but not in the southern hemisphere), then the bisection of day and night at the intersection of the terminator line and the equator is 12 hour each.

But if you look at the northern hemisphere, most of it is in the sun, especially in the daytime. In one place, there is a time difference of 1 hour between the terminator line and the equator. That is to say, in a place, the sun rises at 5 am and sets at 7 pm, so in a place, there are 14 hours during the day and only 10 hours at night.

Is the summer solstice the longest day? How many hours is the summer solstice?

Around the summer solstice, the farther north (the higher the latitude), the longer the day time and the shorter the night time. If you look inside the Arctic Circle, you will find that the sun shines 24 hours a day. There is no night, only day. Because no matter how the earth turns, all the meridians are within the daytime hemisphere. This is an extreme day. On the solstice of the summer of 2020, should we share a room?

On the solar terms of summer solstice

Summer solstice is also called summer season and summer solstice festival in ancient times. The ancients said: the days are long, the shadows are short and extremely extreme, so it is called the summer solstice.

The sun moves to the 90-degree meridian? It is the node of summer solstice, usually on June 2 1-22 in Gregorian calendar. On the solstice of summer, the sun shines directly on the Tropic of Cancer, and at this time, the daylight time in all parts of the northern hemisphere reaches 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.
