The reputation has further expanded, but as the main protagonist of the incident, Bi Fang has begun to have a headache again.

Even if he doesn't go online, Bi Fang can clearly recognize this fact through the extra audience in the live broadcast room, but of course he is not worried about the expansion of his reputation, headache, but a headache in the physical sense.

It's been three days since the volcanic event, and it's the same pinprick feeling in the back again.

The danger is far from over.

Unless that volcano is Tonga, it is absolutely impossible to affect Bifang, who has been running for three days, but which of those super volcanoes is not in the record?

Bi Xiang had come to trust his instincts, and now that the familiar feeling had reappeared, he thought about it and suddenly realized a possibility.

The reason for the pinprick sensation in the first place may not be due to the volcano at all!

On the day of the eruption, it may have been unusual for this, but at least it wasn't because of the volcano when it first appeared.

The sense of crisis appears a full day earlier than a volcanic eruption, and the distance of hundreds of kilometers will not have any effect at all, if this can be perceived in advance, even the prediction is not so exaggerated.

It could only be some other reason, and it is likely that it has already happened, otherwise it will become the same "prophetic" act as a volcano?

Again, this is not possible.

What could it be?

Bi Fang pulled the sail absentmindedly, it has only been ten days now, and he is so fateful.

He finally knew why Nemo Point's mission would be at the T4 level.

This is special, there are no small difficulties, but big difficulties come one after another!

Lives at every turn!

It's ridiculous that I would have thought that there were enough supplies before, and there was no shortage of food and drink, this adventure was just a water mill in time, and the only difficulty was in the rush time.

Bi Fang exclaimed, and the air flow was endless, but this time the accident was different from the last volcanic eruption, and in the afternoon, a fan's barrage suddenly caught his attention.

The source of this danger is revealed.

[Fang Shen, I looked at the weather map, it seems that there is going to be a typhoon in the South Pacific......]

There are millions of viewers in the live broadcast room, and there are many barrages, but Bi Fang was lucky to see it, and his thoughts were like electricity, and he suddenly understood everything.

Typhoon!

It turned out to be this thing!

Thinking of his tension that lasted for many days, Bi Fang was almost certain that it was this fucking thing!

Because it has not yet been completely formed, it has indeed appeared, which has led to a sense of tension in Bi Fang for almost three or four days!

【Typhoon? You're not kidding, are you? 】

As soon as the keyword typhoon was triggered, it was not only Bi Fang who was noticed.

And if someone notices and asks, it will quickly be seen by other people who didn't see it just now, and the phenomenon of human-to-human transmission will occur.

So if there is really any big crisis, it is difficult to miss it in the barrage, because there are thousands of viewers helping to watch.

[I rub, May typhoon? It's kind of funny.

】

[Fang Shen is in the Southern Hemisphere, it happens to be summer, isn't it summer on our side? ] 】

[Death to death, storm, volcanic eruption, another typhoon, Fang Shen, tell me, have you offended anyone? ] 】

[Survival in the wilderness is to go against the sky, and it is normal to die halfway. 】

[Close your crow's mouth!] 】

Seeing that the live broadcast room was about to quarrel again, Bi Fang explained: "There is indeed this possibility, and the possibility is not small. ”

The causes of typhoons are not complicated and generally come from the vast expanses over the ocean in summer.

In the hot summer, the surface temperature of the sea is often above 26°C, the sea water is constantly heated and evaporated, and the surrounding cold air is constantly replenished to the center, so that the center forms a tropical low pressure center.

The hot air rises higher and higher, and when it condenses, a large number of cumulus clouds appear.

This process will release heat, so that the center of low pressure will get hotter and hotter, and the relative air pressure will become lower and lower, and it will become more and more intense.

In addition to a large enough Cumulus cloud, typhoons need to form a large enough area of the ocean, which is why most of the world's typhoons and hurricanes form in the Pacific and Atlantic Oceans.

It is worth mentioning that typhoons and hurricanes are essentially the same, but the sea areas are different: tropical storms in the Pacific Ocean are called typhoons; A tropical storm that forms in the Atlantic Ocean is called a hurricane.

In addition, it is not enough to have cumulus clouds and a vast ocean surface, when two different air currents meet, a vortex is formed in the air, and over time, the Northern Hemisphere begins to rotate counterclockwise to the right under the action of geostrophic deflection forces.

The whirlpool current, which contains a large amount of water vapor cumulus clouds, grows larger and larger, and a huge typhoon eye, which is the center of the typhoon, will form in about 3~4 days.

For example, when the Pacific northwest wind meets the southeast wind from Australia, the two air currents will merge to form a vortex airflow.

And this point in time coincides with Bi Fang's feelings, if this is the case, then today may be the formation day of the typhoon!

With the increase of navigation, the latitude of Bifang is also increasing, away from the equator, there is enough geostrophic deflection force!

I should have noticed it a long time ago.

Bi Fang remembered that before he encountered the volcanic eruption, he felt that the sun was too big and the water temperature was a little too high.

At that time, I didn't think of this possibility.

As the saying goes, as the density of cumulus clouds increases, the space formed by the whirlpool cannot hold more cumulus clouds, and the huge energy needs to be released, and the eye of the typhoon begins to move, at this time the wind speed can reach 50 m/s, and everywhere it goes, it is a mess.

If encountered on the surface of the sea, it is an absolute disaster!

It's the beginning of May, and it's not completely out of summer, and the Southern Hemisphere is still active in tropical cyclones!

Bi Fang's explanation shocked the audience, so is there really a typhoon?

[I don't understand ......]

[In short, just these points, so and so, so and so, do you understand?] 】

[No, the center of the middle and low pressure is getting hotter and hotter, and then the air pressure will be lower and lower, which does not conform to the laws of thermodynamics, shouldn't the hotter the better? 】

[I haven't studied thermodynamics, but I can answer you.] Your assumption is that air molecules of the same mass are available. The reality is that there are molecules of the same volume. Here's the point. Got it? 】

[They are all elders, trembling]

With a reminder, many netizens played their skills and quickly confirmed that there was indeed a typhoon eye in the South Pacific!

This kind of information is very easy to check, and you only need to go to the archipelago national meteorological agency in the South Pacific to see the public data at a glance.

On the afternoon of April 29, after Tropical Cyclone Harold passed over the archipelagic nation of Vanuatu in the South Pacific, its core cloud area became unusually dense and compact, and the central eye became deep and round.

It is evident that it gradually strengthens to its peak under favorable water temperature conditions and atmospheric circulation.

By all indications, another tough battle will follow.
