Weather omen of rainbow

It means: when there is a rainbow in the east, the sun will shine, and when there is a rainbow in the west, it will rain. It will rain if there is a rainbow in the morning, and it will be sunny tomorrow if there is a rainbow at night.

When there are many small water droplets in the atmosphere, sunlight is reflected and refracted by these small water droplets, and rainbows will appear in the sky. According to the location and time of the rainbow in the sky, it can be inferred that there will be sunny or rainy days in the local area.

2. Swallows fly low in the snake aisle, and heavy rain will come soon.

If the swallows fly low in the sky, the snakes on the ground will start to move high, leaving an aisle, which indicates that it will rain heavily.

As for the snake aisle, it was at the beginning of the rainstorm, and snakes could perceive it in advance through the humidity of the air. In order to prevent the rain from flooding their nests or themselves, they will climb to high places, so there will be a snake aisle phenomenon.
