The reason for the moon to the Mid Autumn Festival is particularly clear
At this time, the annual Mid Autumn Festival is ready to come. Family reunion, enjoying the moon, drinking, and talking about family relations are all important activities for celebrating the mid autumn festival since ancient times. On this day, looking up at the moon seems to have a sense of ceremony. Do you know why the moon is the largest, brightest and most beautiful at this time of year?
First of all, from the perspective of meteorological principles, at this time, the dry and cold air from the North forces the warm and humid air that has been circling over China in summer to retreat, and the temperature will be lower and lower day by day. The arrival of autumn wind usually reduces the water vapor, so the clouds in the sky gradually decrease and the visibility is high. In this case, the moon will also appear particularly bright. On the other hand, from the perspective of astronomy, the Mid Autumn Festival is just before and after the autumnal equinox. The time of day and night is almost the same. The moon is located in the due east direction and just receives direct sunlight from the sun in the due west direction, receiving the most sunlight.
Because the moon itself is not luminous and opaque, its light comes from the reflection of sunlight, and only the part of the moon that is directly illuminated by the sun can reflect sunlight. Therefore, from the earth, the strength of the moonlight is related to the size of the moon's reflective surface. When the moon's reflective surface is the largest, it is full, so the moon at the full moon is usually the brightest.
The moon goes around the earth once a month and passes through perigee once. Since the orbit of the moon around the earth is oval, in the process of operation, it is about 350000 kilometers from the earth when it is closest and 400000 kilometers when it is farthest, so there are "big moon" and "small moon" from the earth. When the moon moves to the near earth point of the elliptical orbit, due to the shortening of the distance, the lunar surface will "look" larger than in other positions. In fact, it is the truth that the moon is close, big and far. Around the Mid Autumn Festival, the moon just moves over the earth's equator. At this time, the moon is closest to the earth and reflects the most light to the ground. Therefore, the mid autumn moon looks the brightest and brightest.

Why is it so bright from the moon to the Mid Autumn Festival
The Mid Autumn Festival is one of China's traditional festivals. On the night of the Mid Autumn Festival, the bright moon is in the sky and the clear light is all over the ground, just as Li Bai said in his poem: "the bright mirror is near the danque, and the green smoke is extinguished and the clear light is sent." Han Yu wrote in his poem that "there are many bright moons in the Mid Autumn Festival this year", which also means that the moon on August 15 of the lunar calendar is particularly bright.
The lunar calendar has 12 months every year, 15 months every month, and the moon must be round once. But why is it so bright from the moon to the Mid Autumn Festival? Liu Yuxi said in his poem of watching the moon on the night of the Mid Autumn Festival: "the sky will wash the moon tonight, wash the world and the Ying again, the summer will retreat, the sky will be clear, and the autumn will be clear." Pan Wei also wrote a poem to explain this truth: "is it a farewell to the moon? Just because the autumn is clear." Therefore, the moon to the Mid Autumn Festival is particularly bright, which makes sense from a meteorological point of view. Because at this time, the dry and cold air flow from the North forces the warm and humid air that has been swirling over most parts of China in summer to retreat southward, and the clouds in the sky are reduced. At the same time, the inclination of the sun gradually increases, the sun's light and heat on the ground gradually decreases, and the temperature is lower day by day. The dry and cold winter wind reduces the water vapor and makes the air transparent. Therefore, the autumn is clear, the night sky is like washing, and the moon is particularly bright, making people feel particularly bright from the moon to the Mid Autumn Festival.
Of course, this is also relative. From an astronomical point of view, the moon is not necessarily bright only in the Mid Autumn Festival. Because the moon is bright only when it reflects the sun's light, from the earth's point of view, the strength of the moon is related not only to the size of the reflective surface of the moon seen by the earth, but also to the distance between the moon and the earth and the distance between the moon and the sun. When the surface of the moon reflecting sunlight is the largest and nearly circular, the moonlight should be the brightest, generally on the 15th, 16th or even 17th of the lunar month; At the same time, the orbit of the moon around the earth is elliptical, and the perigee is not necessarily 15; In addition, the earth's orbit around the sun is also elliptical. The perihelion is generally in November and December of the lunar calendar, not in August.
It can be seen that the statement from the moon to the Mid Autumn Festival is also relatively clear. It contains some sustenance and feelings of people.

What does it mean from the moon to the Mid Autumn Festival
The moon to the Mid Autumn Festival is particularly bright, which means that once the moon reaches the Mid Autumn Festival, it will appear particularly bright. We know that every 15th, the moon is very round and bright. Why is it so bright when it comes to the Mid Autumn Festival. We know that in ancient times, the moon represented acacia (in fact, it is the same now), especially homesickness.
When the ancients were missing their hometown, they would look up at the moon. Although they were far away from their family, we could see the same moon as if our relatives were around us. The light of the moon shines on us at the same time. Although we are thousands of miles away, it still seems to be around us. Therefore, it is particularly clear from the moon to the mid autumn festival because we are homesick.
