Weather time-sharing in Quzhou

At 9: 35 am on July 22nd, the once-in-a-century total solar eclipse will be staged over the densely populated Yangtze River Basin in China. This will be a total solar eclipse with the longest duration, the largest number of observable people and the most spectacular scenery in China since 18 14.

The most spectacular total solar eclipse in 500 years will be observed in Quzhou from 8: 30 am to10: 30 am. It's time for a total solar eclipse. I immediately took out my sunglasses and pointed them at the sun. I saw a fiery red sun on a black background, and then it was like a dog eating the moon. The sun bitten by teeth cracked, 1 minute passed. When the moon blocks the sun, it becomes dark as soon as it sets, and there is no trace of the sun. Gradually, I saw things like stars and the black sun. I saw the sun slowly touch for the last time like the fairy's Yaochi Xianlu. It was bright and the stars were gone. What a wonderful world!

But I have no idea why the solar eclipse happened. I just blamed my lack of knowledge, so my father, a know-it-all, told me at once. ................................................................................................................................

It turned out that the solar eclipse was formed after the moon blocked the sun, so the sun could not shine on the earth. The process of total solar eclipse can include the following five periods: initial loss, eclipse, eclipse, luminescence and last contact. We have seen all the five issues, but there are many clouds, and the sun is often in the clouds. The principle of solar eclipse A total solar eclipse occurs because the sun is close to the intersection of the lunar orbit and the earth orbit, and the moon is also at the closest point to this point. An annular eclipse occurs because the sun is close to the intersection of the moon's orbit and the earth's orbit, and the moon is farthest from this point. The eclipse begins with the initial loss, that is, the partial eclipse stage. The moon continues to move eastward, the part of the sun's circular surface covered by the moon gradually increases, and the intensity and heat of sunlight are obviously reduced. When the eastern edge of the moon surface is inscribed with the eastern edge of the sun surface, it is called eclipse. At this time, the entire circular surface of the sun is covered, so the solar eclipse is the moment when the total solar eclipse begins. The total solar eclipse happened because of a magical symmetry. The diameter of the sun is 400 times that of the moon, and its distance from the earth is exactly 400 times that of the moon. Therefore, when the moon is completely between the earth and the sun, for those who are completely in the shadow of the moon, the surface of the sun is completely blocked. The sun turned black, leaving only a golden halo, and the sky turned indigo. Birds will get lost or fly back to their nests, while bats and other nocturnal animals may come out bleary-eyed.

Look, this is a world full of miracles!
