Why the weather in the north is slower than the dark in the south in the summer, the geographical di

This is related to the regression motion of the point where the sun shines directly.

On the day of the vernal equinox, the sun shines directly on the equator, the morning and dusk lines coincide with the meridian coil, and the day and night are equal in all latitudes around the world.

On the summer solstice, the sun shines directly on the Tropic of Capricorn, at this time, the morning and dusk circles are tangent to the polar circle (the ab point in the figure on the right is the tangent point), and the day arc in the northern hemisphere is longer than the night arc in the northern hemisphere. The days are longer than the nights, and by the Arctic Circle, the days are 24 hours long.

On the equator, day and night are always equinoxical.

It can be seen that in the northern hemisphere summer, the length of the day is longer than the length of the night, which is related to the change of the length of the day arc and the night arc under the influence of the position of the direct sun point.

The northern regions get darker in summer than the southern regions, which involves geographical differences.

First of all, it may have something to do with latitude. The northern regions are usually located at higher latitudes, while the southern regions are located at lower latitudes. During the summer months, the Earth is closer to the Sun, therefore, in the Northern Hemisphere, especially in the northern regions, the daylight hours are longer and the nighttime hours are shorter.

Secondly, it may be related to atmospheric refraction. Atmospheric refraction affects the path of sunlight, shifting the position of the Sun as seen on the Earth's surface slightly. At higher latitudes, this shift may be more pronounced, resulting in slightly longer daylight hours.

In general, the northern regions get darker in the summer, due to a combination of factors such as the Earth's rotation, latitude, and atmospheric refraction.

The distinction between day and night is based on the rotation of the earth. So it's not about latitude, it's about longitude and position. The difference in latitude is evident between the north and the south.

If at the same longitude. The time difference is the same. There will be no such situation as the opposite.

There is only one reason, and that is that the longitude position of the north you are in is not the same as the south. Approaching 120 degrees east longitude, that is, the geographical area of the East Eighth District, it gets dark early. If it's in the East Kowloon district, it's even earlier.

Otherwise, it's too late. Brother, what do you compare between the north and the south. China spans five time zones and uses Beijing time, that is, the time in the eighth eastern zone.

Most of the Northeast belongs to the East Ninth District, and Shaanxi belongs to the East Seventh District, so there is basically a two-hour time difference. In addition, because of the existence of the earth's revolution and the yellow and red angles, the earth's axis is tilted, and the sun directly hits the northern hemisphere in the summer half of the year, the higher the latitude, the longer the day, the earlier the day, the polar day phenomenon will occur in the Arctic Circle, and the opposite is true in the winter half of the year. The Northeast region has a higher latitude than Shaanxi, so the summer dawns earlier.

I also found out, personal experience, I am from Hubei, came to Changchun in the northeast to go to university, found that the day dawned so early, in the summer at five o'clock, I thought it was more than six o'clock. In winter, I went to college with my classmates (Hubei), and found that it was almost dark in Changchun, and it was not good to be bright in Hubei. . .

Because it is in the northern hemisphere in winter, the days are shorter and the nights are longer, and the higher the latitude, the shorter the day length, and the longer the night, which means that the sunrise is later in the north and the sunset is earlier.

Winter, when the sun shines directly on the Southern Hemisphere.

For the Northern Hemisphere, daylight hours are shorter. Due to the yellow-red corner.

In winter, the more auspicious the north is, the shorter the daylight, and the south is longer than the north.

It has nothing to do with latitude, it has nothing to do with longitude, the higher the latitude, the shorter the days, the longer the nights, and there will be a polar night in the North Pole.

You don't see the sun all day long. The time of darkness is determined by the geographical location, that is, the geographical longitude of the location.

The question should be asked like this: In the northern hemisphere in winter, does the north with the same longitude get darker earlier than the south? The answer is yes.

Reason: In the Northern Hemisphere in winter, the days are shorter and the nights are longer, and the higher the latitude, the shorter the days and the longer the nights. It means that the later the sunrise is in the north, the earlier the sunset will be.

Yes, that's what causes the north to have cooler temperatures than the south! (Short daylight hours).

On the contrary, the reason why the Northeast produces rice is because it has Kitakura! It is precisely because of the summer solstice that the sunshine hours are up to 14 hours!

Right. The further north you go, the earlier it gets darker, and you think, the North Pole is polar night at this time.

Not necessarily, don't forget that there is a polar day and night.

Yes, we in China are in the northern hemisphere, and due to the rotation of the earth, the north is darker than the south, not only winter, but spring, summer, autumn and winter are all earlier than the south in the north.

Yes. In winter, when the sun shines directly on the southern hemisphere, the daylight hours are shortened for the northern hemisphere.

Due to the yellow-red angle (the earth's axis is sloping), in winter, the north is the shorter the daylight, and the south is longer than the north.

It has nothing to do with latitude, it has nothing to do with longitude, the higher the latitude, the shorter the days and the longer the nights, and there will be polar nights in the Arctic part, and the sun will not be seen all day.

The time of darkness is determined by the geographical location you are in, that is, the geographical longitude you are in. In layman's terms, it is darker in the east than in the west, regardless of spring, summer, autumn and winter. For example, the Xinjiang region of China gets dark earlier than the eastern coastal areas in all seasons, with a time difference of about two hours.

If a region in the north is at the same geographical longitude as a region in the south, then the time of darkness in all seasons is the same in both regions. Hope it helps.

The reason why it gets dark earlier in the south than in the north:

Longitude and latitude will have an impact, but the north and the south should eliminate the east and west influences to compare.

The lower the latitude in summer, the shorter the day length. But the higher the latitude, the longer the twilight time. The sun sets and tilts, so the northern sun scatters longer. If the spring equinox at high latitudes sets at 6 o'clock, it may not get dark until 8 o'clock. At the equator, it is dark at sunset.

Differences between South and North:

1. Climate differences:

Flooding in the south and drought in the north. China belongs to the East Asian monsoon climate, and under the influence of the monsoon, the annual precipitation gradually decreases from the southeast coast to the northwest inland. Not only does the rainy season last for a long time, but floods are also frequent in the south due to the concentration of precipitation in summer and autumn.

However, the lack of precipitation in North China and Northwest China, coupled with excessive reclamation and grazing, and poor ability to store water and resist drought, are facing a serious "water shortage", which affects the production and life of the local people.

2. Humanistic differences:

South economy and north politics. On the whole, military and political activities are active in northern China, while economic and cultural industries are well developed in southern China. The north has always been the political center of China, the Qin, Han and Tang dynasties were Chang'an (now Xi'an), the Yuan, Ming and Qing dynasties were Beijing, and after the founding of the People's Republic of China, Beijing was the capital of the People's Republic of China, which determined the political status of the north in the country.

Since the Southern Song Dynasty, the south is the economic center of China, with developed agriculture, and it is also the main distribution center of the first port, and in modern times, due to the introduction of Western science and culture from the southeast coast of China, it has promoted the economic development of the south, so that the economic and cultural advantages of the south have been continuously strengthened. Therefore, these two sentences of "those who are officials in the north and those who do business in the south" better reflect the different political and economic mentality of the north and the south. Huichun.

3. Industrial differences:

The south is light and the north is heavy. Due to the influence of factors such as resources and location, China's industrial layout has the regional characteristics of light in the south and heavy in the north, that is, heavy industry in northern China is dominated by heavy industry, and light industry in southern China is relatively developed. The main reasons for this phenomenon are:

Northern China is rich in mineral resources such as coal, petroleum, and iron ore, so it has gradually formed an industrial structure dominated by heavy industries such as mining, metallurgy, and machinery manufacturing. However, southern China is mostly rare metals, precious metals and non-ferrous metals and other high-end industrial raw materials, but lacks coal, oil and other basic industrial raw materials, while the south has strong capital and technical force, so it chooses to develop raw materials, fuel consumption of less industrial type, so the light industry is relatively developed. <>

In the summer half of the year, the sun shines directly on the northern hemisphere, and the days are longer in the north of the northern hemisphere, the days in the Arctic Circle are 24 hours, and the equator is always 12 hours, so the north of China is darker than the south in the summer half of the year, and the sun directly hits the southern hemisphere in the winter half of the year, so contrary to the hunger and annihilation above, the south is darker than the north.

The length of the global day is 12 hours at the spring and autumn equinox, and the sunrise is 6 o'clock local time and 18 o'clock at sunset, and the local time on the same longitude is the same, so the sunrise and sunset are at the same time in the same longitude.

Longitude and latitude will have an impact, but the north and the south should eliminate the east and west influences to compare.

The lower the latitude in summer, the shorter the day length.

But the higher the latitude, the longer the twilight time. The sun sets and tilts, so the northern sun scatters longer. If the spring equinox at high latitudes sets at 6 o'clock, it may not get dark until 8 o'clock. At the equator, it is dark at sunset.

In addition, there are many clouds in the south, which has an impact on vision.

Therefore, the time of darkness cannot be generalized. This can happen only when the longitude is the same, between a week or two before the vernal equinox and a week or two after the autumnal equinox.

For example: Hohhot and Yongzhou, Hunan, can be compared.

In summer, the south is black; In winter, it is dark early in the north.

When facing the direction of the rising sun, north is on the left. Sometimes it refers to developed countries, such as Europe and the United States, which are mostly in the north, while developing countries in Asia, Africa and Latin America are mostly in the south.

The contradiction between developed and developing countries is called the "North-South problem". In the quartile division of China's natural regions, the northern region refers to the northern part of the monsoon region in eastern China, mainly north of the Qinling-Huaihe line, east of the Daxing'an Mountains and Wusheling Mountains, and east of the Bohai Sea and the Yellow Sea.

The northern part of China has a temperate monsoon climate, and some areas have a plateau climate.

The characteristics of the temperate monsoon climate are: hot and rainy summer, cold and dry winter, and the average temperature in winter is below 0 degrees Celsius.

The plateau climate is a climate formed on the plateau surface with high altitude, wide ground, and gentle undulations. The climate of the northern plateau of China is mainly distributed in the Loess Plateau and, characterized by:

With the increase of altitude, air, water vapor and dust decrease, and the direct solar radiation increases, especially the ultraviolet radiation. However, the effective radiation has also increased. On the snow-covered plateau, the reflectivity increases and the ground absorbs less radiation, so the net radiation is smaller than that of the plain at the same latitude.

The temperature is low, the daily difference is large, and the annual difference is small;

Precipitation increases on the windward side of the moist airflow and decreases greatly in the interior and leeward side of the plateau. There is more rain in summer and autumn, and less rain in winter and spring;

The wind is strong.
