From the spring equinox through the summer solstice to the autumn equinox, the northern hemisphere is in the summer half and the southern hemisphere is in the winter half. During this period, the days are longer and the nights are shorter in the Northern Hemisphere, and the days are shorter and the nights are longer in the Southern Hemisphere; The North Pole is in the polar day, and the South Pole is in the polar night; The height of the Sun north of the Tropic of Cancer is always greater than the mean and south of the Tropic of Cancer is less than the average. North of the Tropic of Capricorn, the sun rises over the horizon circle in the northeast and sets on the horizon circle in the northwest.
On the equinox, the sun rises due east and sets due west all over the world. From the autumnal equinox through the winter solstice to the spring equinox, the northern hemisphere is in the winter half of the year, and the southern hemisphere is in the summer half. During this period, the length of day and night, polar day and night, and solar altitude in the northern and southern hemispheres were reversed.
North of the Tropic of Capricorn, the sun rises over the horizon circle in the southeast and sets on the horizon circle in the southwest. From the summer solstice through the autumn equinox to the winter solstice, the northern hemisphere changes from summer to winter, and the southern hemisphere changes from winter to summer. During this period, the days in the Northern Hemisphere became shorter, the nights became longer, and the polar diurnal zone gradually shrank. In the Southern Hemisphere, the days are getting longer, the nights are getting shorter, and the polar night zone is shrinking.
The height of the Sun decreases north of the Tropic of Cancer and increases south of the Tropic of Capricorn. North of the Tropic of Capricorn, the rising direction of the sun changes from northeast to southeast, and the direction of falling changes from northwest to southwest. The autumnal equinox rises due east and sets due west.
From the winter solstice through the spring equinox to the summer solstice, the northern hemisphere changes from winter to summer, and the southern hemisphere changes from summer to winter. The variations in the length of day and night, polar day and night, and solar altitude in the northern and southern hemispheres are reversed. North of the Tropic of Capricorn, the direction of the sun rises from southeast to northeast, and the direction of setting changes from southwest to northwest.
From the winter solstice to the vernal equinox and from the summer solstice to the autumnal equinox, the length of the day is approaching the average (12 hours) around the world, and the range of polar day and night is gradually decreasing. The height of the Sun north of the Tropic of Cancer and south of the Tropic of Cancer is approaching the mean. North of the Tropic of Capricorn, the sun rises in a direction that gradually approaches due east and sets in a direction that is close to due west.
From the spring equinox to the summer solstice and from the autumn equinox to the winter solstice, the length of day and night is changing to extremes around the world, and the range of polar day and night is gradually expanding. The height of the Sun north of the Tropic of Cancer and south of the Tropic of Cancer also tends to be extreme. The direction of the rising and setting of the sun north of the Tropic of Cancer moves northeast, southeast, northwest and southwest, respectively.
Due to the complexity of the variation of the length of day and night and the height of the sun between the Tropic of Capricorn and the height of the sun, we have not fully explained it, and it is not difficult for the reader to summarize the pattern on his own. When it comes to analysis, it's best to break it down into several stages. For example, in the Northern Hemisphere, the spring equinox to the direct sun is counted as a phase, and then to the summer solstice is the second phase, after the summer solstice to the direct sun again is the third phase, and then the winter solstice can be regarded as the next phase, and from the winter solstice to the vernal equinox is the last phase, and the sun completes a return movement.
The length of day and night, the height of the sun, the direction of the sun's rise and set, and the direction of the sun at noon (e.g., the sun is north of the zenith at noon during the summer solstice in the northern hemisphere, and south of the zenith at the winter solstice), etc.

This is a natural change in the weather. Nature's law of change! No one can change it. Each season will have its pros and cons. I hope you will experience a different joy in each season!
-
If the weather doesn't get cold, then it's not winter, so winter prepares for the arrival of the cold.
-
If the weather changes, the seasons change, and if people's hearts change, fate will disperse.
The most difficult thing to guess in this world is the human heart, who can be consistent with you, never give up, when difficulties come, who will accompany you, who will accompany you with true love, go forever, in the face of interests, who will give each other?
In these years, the world is hot and cold, people's hearts are changing, and feelings are scattered!
Some people, when you are in the limelight, he swears that he will share the weal and woe, but when you encounter trouble, others have long disappeared.
Feelings, in the face of interests, will fall as soon as they push, they can't stand the test at all, the promise of the mountain alliance and the sea oath, never abandon each other, never say it again, never see it again!
In these years, people's hearts are unpredictable, not all people who are good to you are sincere, some people just think that you have use value, they will be close to you, care about you, some people face you flattery, but behind you you are useless, so, when getting along with villains, you must look at the eyes, to play the routine, see through the don't say it, to the scheming people, see through it and don't say it.
Reality makes you understand, don't be stupid to be good to everyone, leave kindness to people who know how to be grateful, leave sincerity to simple and simple people, those who are hypocritical and play on the spot, they are not worthy of you to be so good to them.
If you can't get in, don't squeeze it, and don't force it if you break the fate. The most important thing in a person's life is: the people who accompany him, and the love of sharing weal and pain. A precious fate, a heart that never leaves.
So from now on, whether it is family, friendship, or love, if you have a heart for me, I will return your sincerity, you will not leave me, I will not give up on you!

True pure friendship does not exist. Modern friendship is still based on mutual use. Imagine that you are a person who has no job to rely on or a person with a meager income, poor economic conditions, poor family background, and needs to be helped by others anytime and anywhere, and you do not have the ability and financial strength to help others, who will become friends with you?

About one-third of a person's life is spent in sleep, which seems to be a fundamental element of biology, but scientists still don't know it. According to the British magazine New Scientist, scientists have come up with several theories about the cause of sleep, ranging from simple theories to complex theories involving memory processing, but none of them have been confirmed. Sleep is made up of two completely different states: >>>More
