Why are the days long and the nights short on the day of the winter solstice, and are the days longe

On the day of the winter solstice, the sun travels to 270° of ecliptic longitude (the point of the winter solstice), and the position of the sun directly hitting the ground reaches the southernmost point of the year, and the sun almost directly hits the Tropic of Capricorn (also known as the winter solstice line), and the sunlight is most inclined to the northern hemisphere. As a result, the winter solstice is the shortest day of the year in all parts of the Northern Hemisphere, and the further north you go, the shorter the days get.

The winter solstice is also the day of the year when the sun is at its lowest at noon in the northern hemisphere. In the Arctic Circle.

To the north, the sun is on the horizon all day.

It is the most extensive day of the year in the Northern Hemisphere. On the day of the winter solstice, the Northern Hemisphere receives the least solar radiation, about 50% less than the Southern Hemisphere, which is in the middle of a scorching summer.

On the day of the winter solstice, the sun reaches the southernmost point of the year, almost reaching the Tropic of Capricorn (23°26 south latitude).'）。On this day, the Northern Hemisphere receives the least amount of sunlight, 50% less than the Southern Hemisphere. The days are at their shortest in the Northern Hemisphere and get shorter the further north they go.

For in the Northern Hemisphere! The day of the winter solstice is the shortest day and the longest night. Because on that day of the sun, the Tropic of Cancer that hit the earth directly!

The sun rises in the east (south) and sets in the west (south) as seen in the northern hemisphere! The southerly has reached its limit.

The sun was shining directly on the Tropic of Capricorn that day.

The winter solstice is followed by long days and short nights。From the day of the winter solstice, count back nine nine days, and the weather will change from the cold solstice of the winter solstice to "warm in the middle of spring". Because the process of "counting nine" is the process of the cold pole warming and the cold warming for a long time, people often call these nine nine eighty-one days "nine miles of heaven" and "counting nine cold days".

Astronomical phenomena. Every year on December 21-23 of the Gregorian calendar, the direct point of the sun travels southward to the extreme, on this day, the sunlight directly hits the Tropic of Cancer (23°26 s), the sunlight is the most inclined to the northern hemisphere, and the height angle of the sun is the smallest, which is the shortest day and the longest night in the northern hemisphere. The winter solstice is also the turning point of the direct sun's return to the north, after which it will go "back", the direct sun will begin to move north from the Tropic of Cancer, and the days in the northern hemisphere (our country is located in the northern hemisphere) will increase day by day.

Although the days in the Northern Hemisphere are short, the temperature on the winter solstice is not the lowest; It won't be very cold before the winter solstice, because there is still something on the surface"Heat build-up", the real winter is after the winter solstice; Due to the great disparity in the climate of various parts of China, this climatic characteristics in the astronomical and meteorological sense are obviously late for most parts of China.

The "winter solstice" is the day with the shortest daylight hours of the year, so it is called the "winter solstice". After the winter solstice, the daylight hours slowly become longer, and the night hours slowly become shorter. That is, the days are long and the nights are short.

Since the "autumn equinox", the days are shorter and the nights are longer, but the length of each day is different.

On this day, the days in the Northern Hemisphere reach the "extreme", so it is called the "winter solstice".

It is not until after the "vernal equinox" that the "days are longer and the nights are shorter". It is also different in the length of each day.

On the day of the "summer solstice", the length of the days reaches the extreme, so it is called the "summer solstice".

The winter solstice is the time when the Sun reaches the Tropic of Capricorn, after which the Sun will move north from the Tropic of Capricorn, to the equator at the vernal equinox, and then continue to move north to the Tropic of Cancer at the time of the summer solstice, and then move south, reaching the equator and the Tropic of Capricorn again at the autumnal equinox and winter solstice, respectively.

Therefore, in the Northern Hemisphere, the winter solstice is the time when the night is the longest and the day is the shortest, and after the winter solstice, the daily sunshine hours will gradually increase, and the summer solstice is the longest day, after which the days will become shorter.

The winter solstice is followed by short days and long nights. The sun shines for a short time, so it is cold.

On the winter solstice, the night is the longest in the northern hemisphere, and after the winter solstice, the days are getting longer and the nights are getting shorter.

On the day of the winter solstice, the sun travels to the point of the winter solstice, and the position of the solar traveler directly on the ground reaches the southernmost point of the year, and the sun almost directly hits the Tropic of Capricorn.

Also known as the winter solstice line), sunlight on the Northern Hemisphere.

Most inclining. As a result, the winter solstice is the day with the shortest days and the longest nights of the year across the Northern Hemisphere, and the further north you go, the shorter the days and the longer the nights.

From the winter solstice to the vernal equinox, the sun shines directly on the point.

Moving from the Tropic of Cancer to the equator, in the northern hemisphere of Somma, the winter solstice is the shortest day and the longest night. After the winter solstice, the days gradually become longer, but before the spring equinox, the days are still short and the nights are long.

After the winter solstice, the days are long and the nights are short. The day of the winter solstice is the shortest day, and the days get longer and longer after that. On the summer solstice, it is the longest day of the day.

On the day of the winter solstice, although the sun is low and the days are short, in terms of meteorology, the temperature of the winter solstice is not the lowest. In fact, it is usually not very cold before the winter solstice due to the "accumulated heat" on the surface, and the real cold is after the winter solstice.

Due to the great disparity in climate across our country, this climatic winter is obviously late for most parts of our country. When it comes to the winter solstice, it marks that it is about to enter the cold season, and the folk began to "count nine" to count the cold days.

The winter solstice is the shortest day of the day, and then the days will get longer and longer, but still shorter than the night, until after the spring equinox, the days will be longer and the nights will be shorter, and then wait until the summer solstice is the longest day of the day, and so on.

If you say whether a day and night on different days are equal in length, then the answer is yes, a day and night are 24 hours. If you want to ask if the length of day and night is the same on different days, the answer is no. The length of day and night is certainly different for the same location, the winter solstice and the summer solstice.

On the summer solstice in the Northern Hemisphere, the direct point of the sun is located at the Tropic of Capricorn, and the days are the longest and the nights are the shortest in the Northern Hemisphere. On the winter solstice in the Northern Hemisphere, the direct point of the sun is located at the Tropic of Capricorn, and the days are the shortest and the nights are the longest in the Northern Hemisphere. For example, the day length of the summer solstice at 40°N is 14 hours and 51 minutes, and the night length is 9 hours and 9 minutes.

Theoretically, the longest day at the same location should be equal to the longest night, without taking into account the refractive effect of the atmosphere. But in reality, the longest day of a year at a location is greater than the longest night because of the influence of the atmosphere.

Not the same length.

At the spring and autumn equinoxes, the sun shines directly on the equator, and the global equinox of day and night. From the spring equinox to the summer solstice, the direct point of the sun begins to move north, and the days in the Northern Hemisphere gradually become longer. By the time of the summer solstice, the daylight hours are the longest, and the sunrise in the northeast is just after 4 o'clock.

From the summer solstice to the autumnal equinox, the day length gradually shortens, and the day and night are 12 hours each by the autumnal equinox. The sunrise is 6 o'clock and the sunset is 6 o'clock in the world.

From the autumnal equinox to the winter solstice, the days in the Northern Hemisphere gradually become shorter to the shortest winter solstice. In winter, we feel that sometimes the sky is not yet dawn at 7 o'clock, and most of it is in the dark of night, and the polar night phenomenon occurs in the Arctic Circle.

After the winter solstice, the direct point of the sun gradually shifts northward from the Tropic of Capricorn, so that the days are longer and the nights are shorter.

Right. It is also the solar term with the longest night and the shortest day of the year.

Yes! Of the 24 solar terms in winter, the shortest day and the longest night are the longest, because the sun returns to the north after reaching the Tropic of Capricorn. There is a time problem with arriving at the South Loop, if you arrive before 12 noon, this day is the shortest, and if the sun arrives after 12 noon on the 23rd, it is the shortest.

Yes, theoretically it was the longest night and the shortest day in the Northern Hemisphere.

Since the winter solstice, the days are getting longer day by day, and the yang energy is rising.

The days are long and the nights are short. The length of day and night is closely related to the four solar terms of the year, and most regions of the earth, on the day of the vernal equinox and the autumnal equinox, are equinoxes, and after the vernal equinox, the days are long and the nights are short; After the autumnal equinox, the nights are longer and the days are shorter; And it's the summer solstice.

Reaches the longest during the day;

On the day of the winter solstice, the night is the longest, and after the winter solstice, the days gradually become longer, the night gradually becomes shorter, and when the spring equinox of the next year comes, it is the same length of day and night, and this change continues until the summer solstice.

The winter solstice is the shortest day of the year in our country, and after the winter solstice, the days will get longer and longer.

For the Northern Hemisphere, the period between March 22 --- September is long and nightly is short.

On the day of the winter solstice, the sun reaches the southernmost point of the year, directly on the Tropic of Capricorn (23°26 s). At this time, the days in the Northern Hemisphere reach their shortest time of the year, which was known as "short days" or "short solstice". In the northernmost part of China, Mohe, there are only seven hours of daylight left, and the polar night (24-hour night) phenomenon occurs within the Arctic Circle.

However, "if you don't", "if you don't", "you will return". The winter solstice is also the turning point of the sun, after which it will take the "way back", so the winter solstice is also called "a yang sheng". After the winter solstice, the position of the sun directly on the ground gradually shifts northward, and the days in the Northern Hemisphere grow longer and the nights gradually shorten.

For people in the Northern Hemisphere, on this day, the Sun is in the Tropic of Capricorn, so the days are the shortest and the nights are the longest.

Because of the sun on this day.

The latitude is the southernmost part.

So it turned out like this.

Why is the winter solstice the longest night?

Because the sun is directly on the Tropic of Capricorn, the days are short.
