What does it mean that thunder and thieves are everywhere at the autumnal equinox? Will it be hot after the autumnal equinox?

What does it mean that thunder and thieves are everywhere at the autumnal equinox? Unconsciously, the autumnal equinox is coming, which is the sixteenth of the 24 solar terms. As an important solar term, on this day, the sun will reach the ecliptic 180 degrees. On this day, the sun will almost point directly at the equator. There will be an interesting phenomenon on this day, that is, the vernal equinox, and the day is as long as the night.

Many people may know little about the autumn equinox. Tell you why the autumnal equinox is so interesting. One is the autumnal equinox, which is divided equally between day and night. When the sun shines directly on the equator, the southern hemisphere and the northern hemisphere receive the same amount of light. After the autumn equinox, the sun will move to the southern hemisphere. By then, the northern hemisphere will be characterized by short days and long nights.

Secondly, cold and summer are equally divided. The autumnal equinox is a solar term with obvious temperature changes. After the autumnal equinox, with the shortening of light time, the summer cold will gradually become stronger and gradually decrease. Third, autumn is equally divided. There are six solar terms in autumn. The autumnal equinox happens to be the fourth day, which is the Mid-Autumn Festival. It is called the autumnal equinox because autumn is equally divided.

The autumnal equinox is an important solar term, and it is also the season of autumn harvest. Naturally, the older generation summed up some experiences of the autumnal equinox. Just like today's sentence "When the autumnal equinox rings, thieves are everywhere". The literal meaning of this sentence is that if there is thunder in the sky at the autumnal equinox, it will have some impact on crops. This year may be a disaster year, or it may be a reduction in grain production, so what is the specific impact?

Speaking of the impact of autumn equinox rainfall on crops, according to the experience summarized by predecessors, the impact is indeed great. ?

First, during the autumn harvest season, too much rain will affect the progress of autumn harvest, at the same time, it will increase the cost of autumn harvest for farmers and cause losses to farmers. Second, the grain harvested in autumn should be dried. If there is no good weather for drying, the grain will retain water and mildew, which will affect the quality of the grain. Third, the autumn equinox season, some places are the season of planting crops in winter. If the rain is too heavy, coupled with the influence of autumn wind, the soil will harden, leading to a decline in the survival rate of crop seedlings, and finally lead to a poor harvest of crops in winter. ?

From these three aspects, in the past rural areas, these situations will reduce grain production and affect people's income and survival. So the old man will say, if these things happen, it will cause famine.

But now it is modern agricultural cultivation. From a scientific point of view, the formation of rain is a natural phenomenon, but we can use our own ability to change the consequences of this phenomenon. There is a weather forecast when it rains heavily. Now the land is well drained and there is little water accumulation. On the issue of drying, there is now a drying field, unlike in the past, when conditions were not mature, everyone scrambled to find a place to dry, and there was a drying field. You can choose a good weather to dry collectively, which rarely leads to mildew of grain. Besides, there are grain dryers now. Even if there is no way to dry the grain, you can use the machine to intervene in the drying. These measures can prevent this from happening, so this proverb is no longer suitable for the development of modern agriculture.

Will it be hot after the autumnal equinox? The possibility of this heat is basically not great. Every autumn rain is followed by a cold rain, and the temperature will drop a little. Of course, this is only particularly obvious in the north. In the south, even if it reaches 1 1, the temperature may remain high. The well-known "autumn tiger" also slowly disappeared in early September. After the autumnal equinox, the heat is small and the cold air is large. We must pay attention to this temperature change. Usually, you should increase or decrease your clothes, don't drink cold water, take a cold bath, and don't eat cold food. These are all problems that need attention after the autumnal equinox.
