Under what weather conditions are Polaris and Big Dipper most likely to appear?

The Big Dipper belongs to the constellation Ursa major, and its names are Shu Tian, Tian Xuan, Apocalypse, Tian Quan, Yuheng, Kaiyang and Yaoguang in turn. If we connect Shu Tian and Tian Xuan, two stars at the mouth of the Big Dipper, and extend the distance to Shu Tian by five times, we will reach a star with the same brightness as these two stars, which is the Polaris. This method is very famous and practical, but in Taiwan Province Province, it can only be used in spring and summer.

(2) The Big Dipper (spoon handle):

This method is to compare your left hand to the shape of six, and then compare your thumb with the directions of Kaiyang and Yaoguang on the handle. At this time, you can find Polaris in the direction pointed by your little finger. This method is special and rarely used. This has nothing to do with the weather, only with the season. As long as it's sunny. . .

As a person in the northern hemisphere, you can see Polaris at any night, and Beidou is relatively high in spring and summer, which is easier to see. The shape of the Big Dipper is easy to recognize. The two stars along the spoon mouth extend five times the distance to find the North Star. I won't ask again
