What it means when it snows on the 15th day of the first month

There is a traditional agricultural proverb. "August 15 clouds cover the moon, the first month of the 15th snow hit the lamp" reflects the echo relationship between the holiday weather

Mid-Autumn Festival is a traditional folk festival in China. As the old saying goes, the moon is very bright during the Mid-Autumn Festival. On the night of the Mid-Autumn Festival, the moon is in the sky,

silver light is shed on the earth. In this pleasant climate,

quiet night,

people gather together,

view the bright moon,

to tell the children that Chang'e moon,

gui tree and the Jade Rabbit's story of divine life.

If the day is cloudy,

the sky is dark,

disappointing!

But it means that the Lantern Festival,

another traditional festival in China,

is exciting with snowflakes flying as families set up their lanterns and decorations.

This is a day when the moon is covered by clouds,

and the sky is bleak,

disappointing!

The relationship between the weather of these two traditional festivals has long been a concern. Over time,

In many places,

August 15 night if the clouds in the sky,

Often the first month of the fifteenth day of the phenomenon of snowflakes. So people summarized: "August 15 clouds cover the moon,

New Year's Day 15 snow hit the lamp" weather proverbs,

was widely spread down.

Of course,

The rhythmic activity of the atmosphere is a very complex problem,

its causes, conditions, performance and many other aspects, has not been made clear,

This regularity is not in every place, every year can correspond to.

Now,

many meteorologists are carrying out in-depth research on the rhythmic activity of the atmosphere and its causes,

Research results in this regard,

For the development of long-term weather forecasting,

is undoubtedly of great benefit.

"Clouds cover the moon" and "snow hit the lamp", on the surface of the clouds and snow echo phenomenon, in essence, is the echo of the relationship between the two cold air activity,

that is to say,

Mid-Autumn Festival around the time of the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity, the cold air activity.

The phenomenon of "clouds covering the moon" was caused by the cold air activity before and after the Mid-Autumn Festival,

. Then,

before and after the Lantern Festival,

there will be a cold air invasion,

the formation of "snow hit the lamp" situation. Therefore, "August 15 clouds cover the moon,

New Year's Day 15 snow hit the lamp" this proverb,

It is the invasion of China's cold air exists for about five months of rhythmic activity reflection. Many weather stations based on this proverb,

studied the rhythmic relationship of cold air activity for about five months,

used it for long-term weather forecasting,

and achieved good results; other days between the weather, there is also such a rhythmic relationship,

only not generally noticed by the people.
