What do you mean, it's sunny in the east and rainy in the west? Meteorological explanation of red rain in the east and red rain in the west.

1, East Rainbow Sunrise and West Rainbow Rain is a weather proverb, which means it will be sunny if there is a rainbow in the east, and it will rain if there is a rainbow in the west.

2. Rainbow is a light image in the atmosphere. It didn't just come out When the atmosphere is very dry, or there are only tiny water droplets in the atmosphere, rainbows will not appear. There will be rainbows only if there are big water drops in the atmosphere. So there is a rainbow in the sky, which means there are big water drops in the atmosphere; At the top of the rainbow, it may have been raining.

The rainbow is in the east, which shows that there is rain in the atmosphere in our east. The atmosphere generally moves regularly from west to east, and the bad weather in the east will only move eastward more and more. If the rainbow is in the west, it means that there is rain in the atmosphere in the west. With the movement of the atmosphere, rain easily falls on us. Therefore, when there is a rainbow in the east, it is not easy to rain locally, while when there is a rainbow in the west, it is likely to rain locally.
