Chapter 361

Talking about lightning.

Here we have to mention a misunderstanding:

That is, the explosion speed of lightning is not the speed of light, but its propagation speed is the speed of light.

The complete lightning is composed of two parts, that is, the leader and the return stroke.

The former is that the air establishes a channel in ionization, and the latter is that the current flows from the ground to the clouds.

In terms of speed, the former is slow and the latter is fast.

The average speed of the pilot process is 1.5 × 10 ^ 5 m / s, about 12000 of the speed of light.

The speed of the return stroke process is much higher than that of the pilot, almost 110 of the speed of light.

So in theory.

As long as the computing power of the equipment is sufficient, the falling point of lightning can be located manually.

And coincidentally

The rabbits can really do that now.

Our current T1 supercomputer provides technical support:

Shenwei Taihu Lake light.

Yes, of course.

At present, tianhe-2 is not the light of Taihu Lake, but tianhe-2.

The annual computational load rate of Tianhe is about 60-70, of which more than 4% is used for weather model calculation.

In the summer with frequent typhoons, it can sometimes increase to 7% or even 7.5%.

After the previous heavy rain in Zhongzhou, Tianhe's computing power has given an unprecedented amount of meteorological simulation - the specific computing power ratio is not clear, but the network transmission is between 8.5% - 9.5%.

In conclusion, Tianhe finally estimated the weather change within 72 hours with an accuracy of 86%.

Don't think that the proportion of 86% is very low. The amount of calculation of this simulation is unimaginable.

In terms of current technical reserves.

Even Tianhe put all its computing power into weather simulation.

It can only artificially interfere with the formation of small acid rain of about 1 square kilometer by non chemical means, and the rainfall is very low.

This is also the reason why a station B up was refuted by professionals that he didn't even know his mother because of the statement of meteorological weapons.

It's actually quite interesting.

In some people's mouths, the technological level of the eagle basically jumps repeatedly between the primitive man and the trisomy

Either it is extremely primitive, even ah San is not as good as it is, or it seems that it has signed an agreement with aliens, or dug out the heritage of the Indian multi universe empire from the earth pit.

To be rational, it is not advisable to belittle or flatter too much.

The so-called long-term vision is not to see Andromeda in one breath

But weather simulation is difficult.

Dynamic lightning capture is still relatively simple. Even we have completed the artificial lightning burst experiment.

The landing point of locating lightning is different from that of intercepting missile. It can be calculated by magnetic induction model.

Here we have to mention a famous system of equations.

It's called Maxwell's equations.

In 2004, the British scientific journal physical world held an event:

Let readers choose the greatest formula in the history of science.

Guess what's the last row of Maxwell's equations?

The end result is

Maxwell's equations, force pressure mass energy equation, Euler's formula, Newton's second law, Pythagorean theorem, Schrodinger's equation and other giants ranked first.

This shows its impact.

The physical meaning of Maxwell's equations is to describe electromagnetic action from the perspective of flux and spinor, that is, from the perspective of field,

It reveals the principle of motor and generator, and predicts the generation of electromagnetic wave.

Considering that some little-known students can't understand this paragraph, we might as well be more straightforward:

It can be said that without Maxwell's equations, you will never see a small movie in your life - because mobile phones may not appear at this time, let alone mobile phones.

According to the second term of Maxwell's equations, the extension of Gauss theorem in magnetic field, and then substituted into quantum field, we can get a very interesting result.

That is, the fractal structure of lightning shows scale invariance, which is also the characteristic of continuous phase transition, which can be explained by resonance percolation.

This is also the generally recognized lightning forming principle.

Yes, of course.

This is still a certain distance from the public opinion. According to the voting results of 18 years, the supporters are about 75%.

Once the structural principle is determined, the rest is very, very simple.

as everyone knows.

The molecules in the atmosphere can be regarded as the potential barrier encountered by the charged particles constituting the current, and the region between the two adjacent potential barriers can be regarded as a potential well.

If the particle energy is near one of the bound state energy levels, the tunneling probability will be close to 1, or resonant tunneling will occur.

The double barrier structure resonating with particles can be formed randomly in the atmosphere, and the discharge intensifies the thermal fluctuation.

And gradually form an ordered structure on a larger scale.

That is, such a double barrier structure appears periodically in space, and finally a percolation phase transition occurs, and a long-range fractal conductive channel can be formed.

The above is the core technical basis of the rabbits' transaction.

Otherwise, you can't capture the dynamic lightning landing point. You can either stand and be struck by lightning without doing anything, or you can directly fix a certain area like other looters.

Return to the chamber of secrets.

At this moment, Ma Ning is introducing to Yang Zhengchu:

"The light super calculation array of Shenwei Taihu Lake is a treasure of the wind spirit and moon shadow family.

Yang people can regard it as a calculation and deduction array.

As long as this array starts operation, it can predict the landing point of Tianlei in advance.

Once we can capture the lightning impact point in real time, we can start the next step. "

Yang Zhengchu almost followed Ma Ning's thinking at this time. He thought:

"I seem to understand what shopkeeper Ma means

That is, first calculate the falling point of 81 sky thunder in each round through the preparation array, then isolate 72 sky thunder by means, and put the remaining nine into it? "

Ma Ning glanced at him in surprise. Unexpectedly, the boss's understanding was much higher than he and the headquarters expected:

"Yes, that's right."

After getting Ma Ning's approval, Yang Zhengchu asked:

"Shopkeeper Ma, not to mention how long the magic weapon blocking thunder robbery can last.

Just the nine heavenly thunder... How do you intend to weaken it? "

Ma Ning didn't answer him directly this time, but took it out of him

A funnel and two plastic bags of sand.

Ma Ning first poured a bag of sand into his hand, and then loosened his left hand.

Shua——

The sand fell to the ground in an instant and scattered into a ball.

Then he picked up the funnel and poured another bag of sand into it.

Soon.

The upper half of the hourglass is filled with sand, and a fine sand line flows out from the lower end of the funnel.

Fine and fast.

But the volume is small.

See this situation.

A glimmer of insight flashed in Yang Zhengchu's eyes and suddenly looked at Ma Ning:

"Shopkeeper Ma, you mean to set up a channel for Lei Jie and let it fall a little bit controllable?"

Ma Ning nodded gently and said:

"Yes, I told you before.

The energy of thunder robbery, or part of the main energy, is the electrical potential energy from it.

Therefore, as long as we stretch its potential energy difference from instantaneous through some means.

In the whole process, the total potential energy difference of mine punishment will not decrease, but will be suspended for a long time.

Then it can reduce the damage of lightning to the body without affecting the forging material.

Just like the sand just now.

One is instant landing, the other is slow decline.

There will be no difference in the total amount between the two. The only difference is the time consumed.

And time

It happens to be the least important factor in the thunder robbery.

Patriarch Yang, you should also know.

It is said that in ancient times.

Some practitioners even spent a whole few days before and after crossing, and finally succeeded in breaking the boundary. "
