Because during the summer solstice, the sun shines directly on the Tropic of Capricorn.
It is the highest latitude that the Sun can reach in the Northern Hemisphere in a year, and it is also the longest daylight day of the year in the Northern Hemisphere, and the higher the latitude, the longer the daylight hours in the Northern Hemisphere.
After the summer solstice, the direct sunlight shifts southward, and the days in the Northern Hemisphere become shorter. The "summer solstice" is the northernmost day of the year, the day with the longest sunshine hours in the Northern Hemisphere, and the day with the most days exceeding the time of night, but the day duration increases from south to north. This is due to the effect of the length of days and the shortness of the night caused by the tilt of the Earth's axis of rotation, which becomes more pronounced the closer you get to the poles.
-
Since the Earth's axis of rotation is tilted, and the morning and dusk lines are perpendicular to the plane of rotation, on the summer solstice, the Northern Hemisphere is tilted to the side of the Sun, and the Sun shines directly on the Tropic of Capricorn, so that the Northern Hemisphere receives light to the maximum, so we will see the longest day in the Northern Hemisphere.
-
This is not determined by the direct exposure of the sun, but by how much of the "Sunday Circle" is exposed above the horizon, and on the day of the summer solstice, the Sun Circle appears to the Northern Hemisphere to show the most arcs, so the sun shines the longest.
-
On the summer solstice, when the sun shines directly on the Tropic of Capricorn, countries in the northern hemisphere will experience long days and short nights, and northern parts of the Arctic Circle.
-
You're talking about all parts of the northern hemisphere, and the opposite is true for the southern hemisphere.
-
The summer solstice is the longest day in the Northern Hemisphere.
Because on the summer solstice, the sun reaches the northernmost point of the year, almost directly hitting the Tropic of Cancer (23 degrees 27 minutes north latitude), and the days in the northern hemisphere reach the longest, and the further north you go, the longer you go. So the summer solstice is the longest day of the day in the Northern Hemisphere.
-
The summer solstice is the longest day of the day in the Northern Hemisphere.
On June 21 or 22 every year, the sun reaches 90 degrees of ecliptic longitude, which is the summer solstice solar term. The summer solstice was first established in the Spring and Autumn period from 722 BC to 481 BC. Scientifically speaking, on the day of the summer solstice, the sun reaches the northernmost point of the year, almost directly hitting the Tropic of Cancer (23 degrees 27 minutes north latitude), and the days in the northern hemisphere reach the longest, and the further north you go, the longer you go.
-
The summer solstice is the longest day of the day. On the summer solstice, the sun shines directly on the Tropic of Capricorn, and the daylight hours are the longest in the northern hemisphere. For the Tropic of Cancer and the regions north of it, the summer solstice is also the day of the year when the sun is at its highest at noon.
As soon as the summer solstice arrives, heavy rains frequently occur in the middle and lower reaches of the Yangtze River and the Jianghuai River basin, which are prone to flood disasters and even pose a threat to people's lives and property. After the summer solstice, the temperature gradually rises, and the diet should be aimed at clearing the heat and increasing appetite, so it is necessary to eat more bitter food, which should be clear and supplemented, not too salty and too sweet.
The length of daylight hours on the summer solstice varies from region to region, with the farther north you go, the longer the daylight hours in the northern hemisphere; "Manuscript of Compliance with the Constitution": "The day is northern, the day is long, and the shadow is short, so it is called the summer solstice." The most solitary, the extreme.
On the day of the summer solstice, the sun reaches the northernmost point of the year, almost reaching the Tropic of Cancer (23°27'N), and the days in the Northern Hemisphere reach the longest and get longer the further north you go.
On the day of the summer solstice, in Shantou, Guangdong, the day is 13 hours and 30 minutes; In Nanjing, the daytime is 14 hours and 12 minutes; In Beijing, the daylight is 15 hours, while in Aihui, Heilongjiang Province in northeastern China, the daytime is as long as 16 hours and 18 minutes. When it comes to the winter solstice, it is 10 hours and 36 minutes during the day in Shantou, 10 hours in Nanjing, 9 hours and 16 minutes in Beijing, and only 8 hours in Aihui.
The above daylight hours are calculated based on the total time from the sun rising above the horizon to sinking into the horizon. However, due to the scattering of sunlight by the atmosphere, there is dawn before sunrise and twilight after sunset, which can make the daylight longer.

No, it's the opposite for the Southern Hemisphere, with the shortest day of the day.

Reason: On the summer solstice, the sun shines directly at the northernmost point of the year, almost directly hitting the Tropic of Capricorn, and the days in the northern hemisphere reach the longest, and the further north you go, the longer you get. After the summer solstice, the sun gradually moves southward, and the days in the Northern Hemisphere get shorter and the nights get longer.
The summer solstice is the northernmost day of the year, the extreme of the sun's northward travel, the longest day in the Northern Hemisphere, and the higher the latitude, the longer the day. This is due to the fact that the "long days and short nights effect" caused by the tilt of the Earth's axis of rotation becomes more pronounced the closer to the two levels.
On the day of the summer solstice, the sunrise direction of all locations on the entire planet except the South Pole and the polar night region within the Antarctic Circle starts from the northeast and sets in the northwest. The summer solstice is the northernmost day of the year, the extreme of the sun's northward travel, and the northern hemisphere receives the most solar radiation, nearly twice as much as the southern hemisphere.
After the summer solstice, the midday solar elevation angle begins to decrease day by day in the area north of the Tropic of Cancer.

During the "summer solstice", the sun shines almost directly on the Tropic of Capricorn, which is the highest latitude that the sun can reach in the northern hemisphere in a year, and it is also the longest day of the year in the northern hemisphere, and the longer the day is the further north it goes. After this day, the direct position of the sun gradually shifts to the south, and the days in the Northern Hemisphere gradually become shorter. The "summer solstice" is the northernmost day of the year, the day with the longest sunshine hours in the Northern Hemisphere, and the day when the daylight hours exceed the night time, but the daylight hours everywhere show an increasing trend from south to north.
This is due to the fact that the "long days and short nights effect" caused by the tilt of the Earth's axis of rotation becomes more pronounced the closer to the two levels.
After eating summer solstice noodles, the day is shorter", the change of day length and night shortening, the higher the latitude, the more obvious it is in the region. So, how long are the days in different parts of our country on this day? Yan Jiarong, an astronomical expert from the Jiangsu Astronomical Society, said that the length of the day (sunset time minus sunrise time) was calculated according to the sunrise and sunset times of these places on the summer solstice
Mohe, the northernmost point in China, has the longest day length in China, with a day length of 16 hours and 56 minutes. The southernmost border of our territory, Zengmu Dark Sand, is the shortest place in our country, with a day length of 12 hours and 16 minutes. The north-south gap is 4 hours and 40 minutes.
Other representative cities are: Harbin has a day length of 15 hours and 43 minutes; The day length in Beijing is 15 hours and 1 minute; The day length in Jinan is 14 hours and 40 minutes; The day length in Shanghai is 14 hours and 11 minutes; The day length in Hangzhou is 14 hours and 7 minutes; The day length in Fuzhou is 13 hours and 46 minutes; The day length in Guangzhou is 13 hours and 34 minutes; The day length in Hong Kong is 13 hours and 30 minutes.
-
Because the position of the Sun and the Earth on this day is on the Tropic of Cancer of the Earth, the daylight hours are the longest.
-
The summer solstice in the Northern Hemisphere has the longest daylight because it is the day when the direct sun reaches the northernmost point, the Tropic of Capricorn.
-
Yes, the summer solstice is cloudy, and the days are shorter and shorter until the winter solstice.
-
The summer solstice is the earliest of the 24 solar terms to be determined. In the seventh century B.C., the ancestors used Tugui to measure the shadow of the sun and determined the summer solstice. The annual summer solstice begins on June 21 (or 22) and ends on July 7 (or 8), and the name simply represents the solar term on the day of the summer solstice, indicating the arrival of hot summer.
On the day of the summer solstice, the day is the longest and the night is the shortest. The days are long and the nights are short.
-
Because the equatorial plane of the earth and the orbital plane (i.e., the ecliptic plane) have an angle, according to the different positions of the earth's revolution, the position of the sun directly on the earth is different, the spring equinox and autumn equinox direct sun point is located at the equator, the summer solstice is at the Tropic of Capricorn, the winter solstice is at the Tropic of Capricorn, because we are in the northern hemisphere, the spring equinox and autumn equinox day and night are equal in length, the summer solstice day is long and the night is short, the winter solstice day is short and the night is long, and the southern hemisphere is just the opposite
-
The summer solstice (June 22) is the longest daylight and the winter solstice (December 22) is the shortest.
On the day of the summer solstice, the sun reaches the northernmost point of the year, almost reaching the Tropic of Cancer (23°26 28 44 north latitude), and the days in the Northern Hemisphere reach the longest and longer the further north you go. It is the longest day of the year in the Northern Hemisphere, and most of the time from sunrise to sunset in the South is about 14 hours.
The winter solstice is the shortest day and longest night in the Northern Hemisphere. The ancients said that the winter solstice is: the solstice of the cathode, the beginning of the yang energy, the solstice of the south of the sun, the solstice of the short day, and the solstice of the long shadow of the sun, so it is called the "winter solstice".
After the winter solstice, the climate in various places has entered the coldest stage, that is, people often say "into the nine", our people have "cold in Sanjiu, hot in Sanfu" saying.
Summer solstice and winter solstice customs:
1. Eat noodles. There is a folk saying of "winter solstice dumplings and summer solstice noodles". On this day, we have the custom of eating noodles in the southern region.
Because from the summer solstice to enter the hot dog days, this season is easy to cause gastrointestinal discomfort, indigestion and other diseases, noodles are softened food is easy to digest. Besides, longevity noodles have the meaning of longevity. Joy noodles have a festive meaning.
Second, support the summer. Supporting the summer is to support the chin, saying that after the summer solstice, people like to doze off, the whole person is listless, the body is emaciated, eat chicken on this day, there are chickens to support the chin, so as not to doze off.

Physiological regularities can lead to a decrease in people's ability to think, a decrease in their ability to exercise, and a shift from outdoor activities to indoor activities. The sound of indoor activities is blocked by the doors, windows and walls of the house, and it is not very loud and cannot be transmitted. >>>More
Because people are active during the day, mosquitoes can't suck blood, so they rest, and the light is strong during the day, mosquitoes don't like it.
Why are the upstairs people all joining in the fun?
How to explain it. You start by thinking about extreme geographical locations, such as the North Pole. At this time, the North Pole (directly before and after the Tropic of Capricorn) is in the polar day. >>>More
