I motioned for everyone to pay attention to the small raindrop-shaped clouds, but when I looked again, I found that the raindrop-like clouds had not changed at all, and were still in the mist.

I rubbed my eyes and wondered, could it be that I was dazzled? After all, he has just escaped from the mouth of the salmon, and it is estimated that his body functions have not fully recovered. My heart suddenly sank, but it wasn't because I drank the water from the lake, and now I have "sequelae"?

I hurriedly asked the old cat, will the lake water be poisonous? He also told me about the water he had just drunk into the lake.

The old cat waved at me, and then said to me that if the lake was poisonous, he was already poisoned, because he had several mouthfuls of water in his mouth, so the old cat signaled that I didn't need to worry too much.

Lin Xihui beside him was a little worried, after all, in this weird environment, the sudden appearance of such strange clouds always made people feel uneasy, and they couldn't help but worry about whether something unpredictable would happen.

For this special kind of clouds, Lin Xihui explained to us that we should not underestimate these clouds in the wild, these clouds are very important geographical "coordinates" in the field, and we often get some important information from them.

There are generally two situations in which the shape of the cloud changes, one is the change of the cloud itself, which is determined by the temperature, humidity and wind structure in the atmosphere, and the waist of this cloud may also protrude some Altocumulus or Stratocumulus clouds under the stable layer. The second is caused by the original clouds moving out of the sky and new clouds moving into our field of vision. For example, the sky was originally transparent Cirrostratus, but when the Cirrostratus moved out of the sky and the gray Altostratus moved in, only the position of the sun could be seen; Eventually, Altostratus moved out of the sky, and the thick, dark Nimbostratus moved into the sky again, and in the lower part of Nimbostratus, a fragment appeared again. This phenomenon of increasing clouds in the sky is caused by the warm front that is about to move over the locality, and it is necessary to pay attention to this time, because there will be special weather.

As soon as Lin Xihui said this, I realized a question, that is, the clouds here should not indicate a natural disaster, right? I have heard about earthquake clouds before, when the 5.12 Wenchuan earthquake in 2008, on May 9, someone saw strange colored clouds in Tianshui, and on the same day, someone in Linyi, Shandong Province also found strange clouds, and there were even large-scale radial striped clouds in Hefei. All kinds of strange clouds, which may be accompanied by geological disasters.

Team Zhang told me not to be nervous, and he pointed out that the kind of cloud I was talking about is commonly known as "seismic cloud", but its scientific name is not "seismic cloud", but "Kowatt cloud". Because the Kovat cloud is often accompanied by earthquakes, it has an additional name for the seismic cloud. The Kowat cloud is a strange geographical phenomenon, and a great geological disaster often occurs a few days or hours after the appearance of the Kowat cloud.

There are two more scientific explanations for the Kovat cloud, one is the heat theory, when a geological disaster is about to occur, due to the geothermal heat accumulating in the earth's crust, or due to the intense friction of the rocks in the underground seismic zone under strong stress, a large amount of heat is generated, and the heat escapes from the surface of the earth, which warms the air and produces an updraft, which forms a 'Kovat cloud' at high altitude, and the tail end of the cloud will point to the place where the geological disaster occurs. The second is the electromagnetic theory, in which the 'piezomagnetic effect' occurs on the rock under the action of in-situ stress before the disaster, which causes local changes in the geomagnetic field; in-situ stress causes the rock to be compressed or stretched, causing a change in resistivity, so that the electromagnetic field has a corresponding local change. Due to the influence of electromagnetic waves on the upper ionosphere, the concentration of ionospheric plasma decreases sharply, resulting in the non-free orderly arrangement of water vapor and dust to travel the Kowatt cloud. But in the situation we are in, the second electromagnetic doctrine does not apply, because there are no rocks here. On the other hand, the first thermodynamic theory is also a bit far-fetched, as it is in a state of high temperature all year round, and the geothermal distribution is relatively dispersed, and there is no sudden accumulation.

Lin Xihui also said that these clouds do not look like Kewatt clouds from the outside. Kowatt clouds are generally gray, orange-red, and dark red, and the clouds and the sky are very clearly bounded, mostly in the shape of ripples. The cloud forms we see are all teardrop-shaped, but the shape of the Kowatt cloud is generally multiple clouds, the kind of clouds are parallel or radial clouds, and for parallel clouds, the center of the radial cloud is the center of the circle to which it is arced. There are also ichthyos-scale clouds: loose fish-scale clouds formed by large clouds in a few hours, mostly appearing at the same time as "multiple clouds", and the depth of the clouds is distinct; The last type is a clump cloud: a large or clumpy cloud in the shape of a solid shape that appears at the epicenter of an earthquake. A typical Kowatt cloud would be one of these three forms.

"What if this is the fourth strange form of Kowat?" The bald man didn't know each other.

Lin Xihui squinted at his bald head and said, "If that's the case, you can only consider yourself unlucky." Now we are in the mountains, and if there is a natural disaster, you and we will not have time to run, and we will not have anywhere to run. So, let's pray that the clouds here are not weird. ”

I asked the old cat again, is the right path we are taking now? Why did we walk for so long, but we didn't get any closer to that ancient building?

The old cat nodded, just motioning for us to hurry up, and it would be okay to follow him.

So we continued walking, and the clouds in the sky were still in the shape of small raindrops. After watching such a strange scene for a long time, I am more and more amazed by the magic of nature, and the sky is like a frozen picture, which is pleasing to the eye.

At this moment, a drop of water suddenly fell from the sky and hit us ticking. The water droplets were sporadic at first, but soon, the small fish turned into heavy rain, and the rain became heavier and heavier, and slowly it became heavy rain.

"Let's go!" The old cat said to us loudly, and when he had finished speaking, he immediately ran in front, and his movements were very large, and the expression on his face was very nervous.

I wondered in my heart, it's just raining, is the old cat so nervous? Besides, we had limited water supplies, and now it is raining at this time, which is not a timely rain.

However, after the old cat ran up, several of us had to run along. The bald head and the Zhang team were probably worried that I would not be able to do anything under my feet, so the two of them directly set me up, and the three of us ran forward in a strange way.

The bald head couldn't help but ask the old cat, "Little brother, are you holding your pee?" You don't have to run so fast. ”

The old cat looked back at us, then at the air, and said to us solemnly, "If we don't reach that tower soon, we'll all die here." Because we are now in the Feng Shui pattern - Huangquan Tianshui! ”
