There is a joke in the entertainment circle that it will rain when Jam Hsiao comes. Judging from all kinds of evidence, there seems to be a causal relationship between Jam Hsiao and rain. Is this a scientific conclusion? Many people can see at once: how can this be science? This is a complete joke. ?

In fact, the relationship between Jam Hsiao and rain is not even an association rule, let alone a stronger causal relationship. Because there is no necessary connection mechanism between the two, even if the phenomenon has always existed (even if it is 100%), it is just a joke. ?

So, is the relationship between earthquakes and clouds more like science? If according to limited observation, there must be strange clouds before the earthquake, can the relationship between them be scientifically proved? ?

First of all, it depends on whether there must be an earthquake behind this strange cloud. Before we can prove it, we must define strange clouds. How strange the cloud is that there are 10 thousand kinds of Hamlet in the hearts of 10 thousand people. The legendary "strange cloud" refers to the color of white, gray, orange or orange, and the strong wind is not easy to change its shape. There is a clear boundary between the sky and the clouds, some are like traces left by airplanes, and some are wavy or radial, but this is too common! However, it is said that the cloud like a plane scratch through the last flight of stairs generally indicates that the epicenter is on the vertical line of the cloud direction, and there will be an earthquake two weeks later, and the wavy cloud generally indicates that there will be an earthquake after 1, and so on. ?

Of course, the legend has already told all those seemingly strange but actually ordinary shapes. We only speculate based on the above characteristics, how many "strange clouds" should the global population of more than 7 billion point out? ?

But on a global scale, there are only a few earthquakes above designated size every day on average. How can it be paired with so many earthquake clouds? Secondly, we should consider how many kilometers between clouds and earthquakes can be considered to be related. There are many articles explaining the earthquake cloud, but most of them say that the longer the strange cloud stays in the air, the closer the epicenter is to the place, but there is no specific mention of 1000 km, 2,000 km or 4,000 km. ?

In short, if there is no final mechanism to explain and identify, it is feasible to interpret the relationship between the two phenomena, and anyone can guess. Neighbor Wu Ni's mother often said that people are made of mud, otherwise how can the mud on their bodies be wiped away? Because of this, when I was a child, I immediately regarded Wu Ni's mother as a scientist and philosopher. I didn't know this was called simple materialism until I went to middle school. But people's cognition is different. If you say that the rearrangement of clouds caused by the change of geomagnetic field is the explanation mechanism of the relationship between earthquakes and clouds, it may make people without scientific literacy agree at once, but these are all fallacies. ?

On the other hand, the relationship between earthquake and rain seems more acceptable. Generally speaking, there are often heavy rains after earthquakes, and it is a long time. However, please note that some earthquakes have not rained for a long time. But guess is guess after all. Although it is hard to deny, verification is almost impossible. ?

But why is it raining in a new place in Jam Hsiao? When an earthquake comes, it may or may not rain. The latter is more like a scientific conclusion than the former. ?

To understand earthquake rain, we must first understand the formation principle of rain. Water is irradiated by sunlight, which turns into steam and evaporates into the air. At high altitude, water vapor will condense into small water droplets when it meets cold air. They are small and light, held in the air by the updraft in the air, and then gathered into clouds. But the water droplets are too small to fall into the rain, but if the moisture in the air keeps increasing, the water droplets collide and fall back, or there is dust in the air, which becomes the condensation nucleus of water droplets, thus promoting rainfall. ?

The formation process of rain (picture from the network)?

After the earthquake, many cracks on the surface release a lot of heat into the earth, which at the same time increases the surface temperature and strengthens transpiration, so that underground water vapor enters the air along the cracks on the surface, and the water vapor in the air tends to be saturated. At the same time, after the earthquake, with landslides and the collapse of buildings, a large amount of dust will also enter the cloud with the updraft and become the condensation nucleus of small water droplets, thus forming post-earthquake rainfall. ?

Secondly, the earth itself is a big magnet, which will excite a magnetic field around it, and when the crust changes, it will also cause changes in the surrounding magnetic field. Clouds in space are charged, and clouds in magnetic field also change because of this change of geomagnetic field. This disturbance of the magnetic field breaks the original balance, and the disturbance produces a cyclone of the magnetic field, and charged clouds will gather here, and it will rain if they gather too much. ?

It rained after Xingtai earthquake, Tangshan earthquake and Wenchuan earthquake. It is easy to understand that although the crustal movement will bring about local airflow changes, this change may not necessarily lead to raindrops condensation. Therefore, the rain after the earthquake is a probability phenomenon, not an inevitable result. ?

Finally, we will find sadly that it seems that Jam Hsiao is more reliable than science. He is sure, but it is not necessarily the earthquake that brought rain. In a word, science needs to be verified repeatedly, and it is futile to explain imaginary conclusions with no amount of explanations. Moreover, earthquakes that cannot be predicted in time are even less likely to have signs of astronomical phenomena a week or two ago. In a word, if this "strange cloud" above me will cause a vertical earthquake, I can only laugh it off. ?
