What does the moon have to do with the weather?

According to the forecast of the meteorological department, the weather will be good in the next few days, mainly cloudy. The Mid-Autumn Festival just passed coincided with a cloudy day, and many people felt sorry for the absence of the moon. In fact, many times, as long as we look up to see if there is a moon in the night sky and what the shape of the moon is, we can predict the weather ourselves. The moon is the closest celestial body to the earth and the only natural satellite orbiting the earth. When it goes around the earth, it will look different.

This shape is called the moon phase, depending on the size of the part of the moon seen by the sun from the earth. The moon is closely related to the weather.

As the saying goes, "when corn is born on the moon, the weather changes." Although there are no clouds in the sky, we can see the moon wrapped in several small rings, shaped like "corns". This shows that the air humidity begins to increase, which is beneficial to the formation of rain clouds. As filamentary cirrus clouds or gauze-like cirrostratus spread in the sky, a halo with a large viewing angle radius was reflected around the moon, indicating that the water vapor and ice crystals in the sky continued to increase and the weather began to deteriorate.

There is also a proverb: "There are few stars in the moon, but it is sunny". At this time, the atmosphere is clear, dry and stable, with high transparency, especially in autumn, which indicates sunny weather.

When walking after dinner, if there is a moon in the sky, try to look at the moon and get to know the weather, so that you can not only appreciate the beautiful moonlight endowed by nature, but also detect the changes of the weather. Kill two birds with one stone, isn't it fun!
