The reason for early darkness in winter: the sun is located in the southern hemisphere, far from the northern hemisphere, resulting in a short time of direct sunlight, which leads to short days and long nights in winter, so it is early to dark.
In life, you can feel that the sky gets dark very early in winter, much earlier than in summer. In addition, the nights are significantly longer than the days in winter. What is the reason for this? Let me give you a specific introduction.
Detailed content
01
It is related to the distance from the direct point of the sun. In winter, the sun is located in the southern hemisphere, so the northern hemisphere is far away from the sun, which leads to the phenomenon of short days and long nights in the northern hemisphere, and it will get dark earlier in winter.
02
On the contrary, in the Southern Hemisphere, when it is close to the direct sunlight point, there will be long days and short nights in the Southern Hemisphere.
03
Only during the vernal equinox, the sun enters near the equator, when the length of day and night are equally divided.
04
Every year after the winter solstice, the sun begins to return to the equator on December 22, when the day and night begin to change, the days begin to lengthen and the nights begin to shorten, until the spring equinox day and night are the same length, both 12 hours.
05
The earth is not in a hurry to turn itself around, and it still revolves around the sun, which is why there are four seasons in a year. The direct position of the sun on the earth will affect the illumination time of a certain area on the earth.
