When Lucifer was bored this morning, he touched his chin and thought: "By the way, this thing is really magical. Where did the storm curse I sent go? How come you can't see people alive but not corpses...ah?
No, I searched all the people in heaven who might be hostile to Hong Dali and found no one who was hit by the storm. Could it be that this curse is invalid? Or that the power of my curse has lost its effect? It doesn’t seem like it.
...Could it be that something strange happened to Hong Dali again? Well, it's possible. This Hong Dali is really miraculous..."
…
"Ah Sneeze," Hong Dali, who was on the deck of the Big Fish, sneezed fiercely and touched his nose: "Who is talking about me?" He said and sneezed again: "Ah Sneeze, a hundred years old.
!His grandma, the weather is quite warm now, why do you keep sneezing..."
…
The butterfly effect, also called topological chain reaction, means that in a dynamic system, small changes in the initial conditions can drive long-term huge chain reactions of the entire system. This is a chaotic phenomenon. There are certain factors and consequences in the development of anything.
Variables, the development trajectory of things in the process of development has rules to follow, and there are also unpredictable "variables". A small change can affect the development of things, indicating that the development of things is complex.
And this is where the magic of nature lies...
After Hong Dali sneezed twice, he went into the Big Fish island to sleep with Li Nianwei without any care (don't think wrongly, he was looking for his thighs...), but his two sneezes were something special.
…
At this time, the Big Fish is traveling on the route to the Bermuda Triangle, which is already in the tropical ocean. On the sea surface, there are often many weak tropical vortices. In professional terms, these are the "embryos" of typhoons.
", because typhoons always develop from such weak tropical vortices.
Actually, it was nothing, but the problem was that Hong Dali sneezed twice...
The sea around his Big Fish is vast enough, and it is a tropical ocean. The surface temperature of the sea water is higher than 26.5°C, and in a layer of sea water 60 meters deep, the water temperature exceeds this value. It is vast.
The ocean surface is a necessary natural environment for the formation of typhoons because of the friction between air molecules inside the typhoon. An average of 3100-4000 calories/cm**2 of energy is consumed every day. This huge energy can only be produced by the latent heat released by the vast tropical ocean.
Possible supply. In addition, the strong winds rotating around the tropical cyclone will cause the sea water near the center to churn. In the center of the typhoon where the air pressure drops very low, it can even cause the ocean surface to surge upward, and then spread out. Therefore, the sea water will flow from the center of the typhoon.
Throwing around.
Originally, such an environment was only likely to form a typhoon, but not necessarily a typhoon.
Before a typhoon forms, an initial disturbance is needed, just like a spring oscillator. It will not vibrate without a disturbance.
And Hong Dali's two sneezes were exactly this initial disturbance!
First, there is a very weak tropical vortex around the Big Fish.
We know that the operation of any machine consumes energy, which requires an energy source. Typhoon is also a "heat engine". It rotates at such a huge scale and speed and consumes a lot of energy, so it needs
There is a source of energy.
The air blown out by Hong Dali's two sneezes merged with the very weak tropical vortex, making the very weak tropical vortex a little bit stronger, and began to move very, very slowly.
In this tropical vortex, the air pressure itself is lower than that of the surroundings. After Hong Dali's two sneezes merged in, the vortex moved and the air pressure gradually became lower. The surrounding air carried a large amount of water vapor and flowed to the center of the vortex, and
An upward movement occurs in the vortex area; the moist air rises, water vapor condenses, and huge latent heat of condensation is released, which starts to make the big machine of the typhoon run.
When the Big Fish aircraft carrier advanced more than ten nautical miles, the tropical vortex affected by Hong Dali's two sneezes had initially formed a certain size - about twenty centimeters in diameter.
To say that the diameter of more than 20 centimeters is actually smaller than a hair on the top of a person's head on the vast sea, but we know that things are developing - this happens to be a tropical ocean.
The water temperature is very, very suitable. The tropical ocean surface with high temperature and humidity supplies water vapor. The air rises strongly, causing condensation and releasing latent heat. A typhoon has already taken shape.
But just like this, this small vortex is not enough to cause any harm. It is very likely that if it encounters the slightest interference, it will disappear in the sea forever.
But the real problem is that at this time, coincidentally, a gust of sea breeze happened to blow by, which caused a more violent reaction - the sea breeze merged into the vortex, and the low temperature brought by the sea breeze increased even more
Due to the temperature difference in the vortex, this small tropical vortex became more and more spectacular - from a diameter of about twenty centimeters to about one meter.
At this time, this small tropical vortex moved faster and faster. About an hour later, it happened to move to a latitude that was very suitable for the formation of typhoons. The formation of typhoons requires certain conditions.
The earth's rotational deflection force is large enough, because the geostrophic deflection force at the equator is zero and gradually increases toward the poles. Therefore, the location of the typhoon is approximately 5 or more latitudes away from the equator. This tropical vortex is just at this latitude.
Due to the rotation of the Earth, a force is produced that changes the direction of the air flow, which is called the "Earth's rotation deflection force." When the tropical vortex moves here, the effect of the Earth's rotation makes it difficult for the surrounding air to flow directly into the low pressure.
Instead, it rotates counterclockwise along the center of the low pressure.
At this time, this small tropical cyclone had grown a little bigger, reaching a diameter of more than two meters.
At this time, it still looks so small, just like a small seed that is slowly sprouting and growing.
In this small tropical vortex, just above the weak low pressure, the difference in wind direction and speed between high and low altitudes gradually decreases. Soon the upper and lower air columns act in unison, and heat rapidly accumulates in the upper air, thus increasing the temperature.
As the ambient airflow above the friction layer flows along the isobars, the upper-level warming effect is further completed. This small tropical vortex quickly grows and grows, and soon the diameter reaches three, four, or five meters.
rice……
If it's just this scale, it's obviously not enough.
But the problem is that the sea surface here has formed strong cumulonimbus clouds after a day of exposure.
That small tropical cyclone passed by and brought a lot of cold air due to the wind speed. At this time, the hot air in the cumulonimbus clouds on the sea surface rose, and the surrounding colder air continued to replenish it. When it met again,
The heat rises and circulates like this, quickly making the air above hot and the air below cold. The water vapor in the hot air above evaporates and expands the scope of the cloud belt.
At this time, this small tropical cyclone already had a diameter of nearly fifteen meters. The expansion of the cloud belt made the hot and cold motion more intense. Then, the expanding cloud group was affected by the geostrophic deflection force and began to gradually
Spin quickly.
The centrifugal force generated by the rotating air throws the air outwards. The air in the center becomes thinner and thinner, and the air pressure continues to decrease. Finally, this small tropical vortex completely sprouts, grows up, and becomes more and more mature. Finally,
, reaching a diameter of nearly thirty meters, and entered the initial stage of the typhoon.
…
United States Weather Bureau.
The staff were yawning out of boredom and discussing various events that had happened in the world in the past two days.
"Hey, Jobs, have you seen the news in the past two days? Our country's three aircraft carrier formations have conducted naval exercises. This is a rare large-scale action." A staff member of the Meteorological Bureau glanced at the screen in boredom, and then rushed to his side.
colleagues said.
"Of course, how could you not know about such a big thing," the colleague smiled and said, "It's a miracle that such a big battle was fought for a prodigal. To be honest, I feel like it's a bit of a fuss."
"Well, no matter what, he is just a prodigal son. What he did was really too much." The man from before shook his head: "These people have nothing to do and are wasting military money. They really have too much money and no place to spend it. Aircraft carriers
Once you go out to sea, tens of millions of dollars will be lost."
"Stop worrying about high-level affairs," the colleague sat on the sofa, looked at the satellite cloud image again, and suddenly said in surprise: "Look, what is this?"
"Huh? What's wrong?" The first person hurried over and quickly said with a smile: "It's just a small typhoon, look at you so panicked."
"Haha, I'm a little nervous." On the satellite cloud map, a typhoon with a diameter of only thirty meters is moving towards the United States. However, for everyone at the Meteorological Bureau, there is no need to worry about such a small typhoon. Under normal circumstances
Next, such a small typhoon disappeared before it even made landfall.
"Okay, okay, don't do useless things," the director of the US Weather Bureau walked in at this time: "Everyone, hurry up and get to work!"
…
No one at the US Weather Bureau paid any attention to this small tropical vortex. After all, it was so small that no one even bothered to mention it.
But this little tropical vortex is still working hard to move and grow...
Because the central air pressure of the tropical low is lower than that of the outside world, the surrounding air rushes into the tropical low and rises when heated, supplying the tropical low with more energy than the output energy. At this time, the air in the tropical low rotates more violently, and the maximum wind force in the center increases.
, the central air pressure further decreases.
Finally, the maximum wind force near the center reached about 60 kilometers per hour. At this time, this small tropical vortex finally successfully upgraded to a level. It was upgraded from the seed-like tropical depression at the beginning to the intensity of a tropical cyclone.
