Thunder and rain are small, thunder and rain are small.

In our life, we can often hear such a word combination-more thunder and less rain, so what does it mean? What is the source? Let me find the answer with you!

Cry more and rain less.-only names.

"Much thunder and little rain" is a metaphor for exaggeration, and actual actions are not as much as words say. [Source] Songshi Daoyuan's "Jingde Dengchuan Record" Volume 28: "Thunder is very loud, no raindrops." As the saying goes, much thunder and little rain can be regarded as crying, just making a sound, but not really crying.

About "more thunder and less rain";

"Much thunder and little rain" is a common idiom. It described the plan as grand, loud, clear, or magnificent, but there were few actual actions.

But from a scientific point of view, "more thunder and less rain" does not conform to the weather facts.

Because, in all kinds of rainy weather, the raindrops of thunderstorm are not only not small, but also the biggest. The reason is that rain drops condense in the updraft in the clouds. Therefore, only in a strong updraft cloud can heavy raindrops fall. In 2004, a meteorologist observed heavy raindrops with a diameter of 1 cm in Marshall Islands and Brazil, which was recorded in the Guinness Book of World Records. Brazil and Marshall Islands are tropical regions, where rain basically comes from lightning, thunder and cumulonimbus clouds. Cumulonimbus clouds have the strongest updraft in nature. On the contrary, the smallest raindrop in the world, Mao Mao Rain, was born in the cloud with the weakest updraft, and even the smallest raindrop could not be suppressed.

Of course, idioms belong to the category of literature, so there is no need to stick to facts completely. Moreover, although the raindrops of thunder are not small, they are "not many". And "light rain" and "light rain" are consistent in the direction of quantity.

⑤ Thunderstorm weather has three main characteristics: besides thunder and thunderstorm, there are also thunderstorms and strong winds. As we all know, lightning can travel far (there is a proverb called "more thunder than rain"); Thunderstorm and gale are shock waves that are sent around because the air pressure is much higher than the surrounding area when the cold air (high density) sinking behind the cumulonimbus cloud accumulates rapidly on the ground, and can also spread to far places. However, thunderstorms are different. Although its scope is basically the same as that of the sinking cold air flow, it will not expand, and the rain area is also a narrow strip formed with the advancement of cumulonimbus clouds (relative to the gale lightning area). That is to say, in most areas affected by thunderstorms, there are only thunder and strong winds, and there are no raindrops. The proverb "Lei Gong sings first, but it doesn't rain much" means "more thunder and less rain". However, after all, "light rain" and "light rain" are not the same thing, and idioms must have another source.

6. That's true. At first, this idiom was not called "much thunder and little rain" at all, but evolved from "much thunder and little rain". Interestingly, this is quite true, because it is true in the area affected by lightning weather, except for thunderstorms. However, this eight-character is not an idiom, nor is it catchy. If we want to reduce it to six words and keep "much cry and little rain", then the word after "raindrop" has no choice but to be "small". Because "big" is only against "small". Of course, "thunder, no rain", but the contrast is not strong.

More importantly, the saying "more thunder and less rain" accords with some social realities. Because, there will always be some "trumpeter" practical actions. It can even be considered that the two scientific terms "thunder" and "raindrop" are used only because of the need to form idioms. These human factors may be an important reason why idioms become "more thunder and less rain".
