In an instant, a large black object "smashed" down along the rapid flood.

Even though Gu Ji shouted in advance, the rubber boat still didn't have time to dodge and was hit hard by the black mass on the stern, and the hull began to shake violently.

"Everyone, hurry up!"

The rescue commander and Gu Ji shouted in unison.

Fortunately, the black object was just a pile of branches entangled by the water flow. The hull quickly stabilized under the control of the driver. If it had been the glass that had smashed the train before, the entire rubber boat would have been overturned.

Suddenly, a dazzling white light flashed across, like a giant python leaping on the clouds, several bursts of thunder sounded, and the rain intensified.

The formation commander picked up the waterproof loudspeaker and urged the boat troops to evacuate as soon as possible.

This made Gu Ji feel lucky. If he had urged the central cabinet government to slow down a little more, the transport plane would have been unable to land at this time. While chatting with the lifeguard, he learned that a total of 9 IL-76s had been dispatched from the Indian Air Force base.

and the C-17 strategic heavy transport aircraft introduced at a sky-high price.

Since it is so willing to spend money, the cabinet government cannot waste such a good publicity opportunity.

Gu Ji noticed that among the boat force, at least four or five rubber boats were equipped with professional photographers responsible for capturing rescue details.

"Vidi, look!"

Fatima suddenly tugged on his sleeve and pointed to the water not far away where the light of the rubber boat was shining.

It turned out that the top was covered with dead branches and weeds similar to the ones just now, and occasionally a stone could be seen splashing out. Even the edge of the kayak was already covered with mud from the turbid flood water.

Gu Ji glanced back, thoughtfully.

"It seems there was a mudslide on the river bank."

From the beginning, he felt that the flood was extremely turbid. Opening his eyes in the water was like being rubbed by sandpaper. The conditions for the formation of mudslides are often steep terrain, abundant loose sediments, sudden or continuous heavy rains or large amounts of debris.

When melted ice water flows out, the viscous mudslides erupt suddenly and fiercely, carrying up to 80% solid matter, which is extremely destructive and much more terrifying than floods.

The shape in front of you is more like a rare debris flow, with water as the main component, little clay content, and solid matter accounting for 10-40%. It is highly dispersed, but the sediments will also damage the ecology and traffic.

Gu Ji immediately found the rubber boat commander and asked them to try to avoid the train tunnel and hills ahead.

"In addition, I suggest that you turn off the outboard motor in time and lift it up, and instead use paddles and pennies to paddle. We are in a mountain and forest environment with narrow passages, low water levels, and too many solid objects in the water.

It is easy to entangle the external propeller or clog the injection pump. Once the power system is damaged in large quantities, subsequent rescues will be difficult!"

He proposed to the Cabinet Secretary from the beginning to use detachable external power.

On the one hand, it is convenient for disassembly and transportation and saves space; on the other hand, considering that flood sediments usually contain high amounts of sediment and other impurities, the underwater visibility is low, and there is a lack of basic data of waterways and navigation marks and navigation light guidance, so a large number of floods

Obstacles such as wires and cables, tree trunks, and mounds under the water, as well as a large number of debris floating on the water, make the water environment extremely complex and have a great impact on boat navigation.

The commander is a square-faced Indian guy in his mid-twenties.

After hearing the suggestion, he was slightly startled, as if he was a little surprised as to why Gu Ji knew so much, and subconsciously asked: "Are you..."

“Vidhi Daly, Deputy Disaster Commissioner, Assam Emergency Management Command!”

After hearing Gu Ji's identity, the commander suddenly realized that he was an expert in disaster management.

But what he didn't know was that Fatima beside Gu Ji was also an expert and specialized in meteorology and flood disasters, but she didn't understand the knowledge of search and rescue by boat on the water.

In fact, looking at the entire state disaster management department, even Minister Anurag is not as "erudite and talented" as Gu Ji.

Meteorological analysis, formulation of emergency response strategies, on-site command, crisis medical first aid, and now there is an additional water rescue.

It can simply be described as a monster.

While the commander reported to the commander-in-chief of the formation, Gu Jize pretended to be deep in thought and secretly began to study meteorological rewards and mission objectives.

He clicked on the reward with his mind.

Instantly, a translucent dynamic light screen appeared in front of me, which displayed a partial map of the world. The Bay of Bengal and a large amount of colorful smoke-like gases were condensing on the ocean. The outermost layer was white, and the pink became darker towards the center.

Until it turns pink.

"As expected of military data, it's so detailed."

Gu Ji was surprised by the complexity of the Navy's forecast model. The model dynamically covers the weather forecast for the next 10 days, including ocean surface air temperature, cloud formation, cloud movement forecast, low-altitude wind forecast, atmospheric heat flux, etc.

These meteorological data are not just for weather forecasting.

For example, low-altitude wind is very important for the accurate flight and guidance of military aircraft, missiles, and drones; ocean surface air temperature is involved in calculating atmospheric waveguides in electronic warfare; predicting cloud movements is to support offensive and defensive intelligence, surveillance, and reconnaissance missions.

The only thing that's more troubling is the accuracy.

The unit pixel accuracy of the latest weather model developed by the United States can reach 3.5 kilometers. Xia Guo partially achieved ultra-high accuracy of 100 meters in the Winter Olympics. Although the Indian Navy forecasts the macro-bay area, the accuracy is only a dozen

Kilometers are still at the level of the United States seven or eight years ago.

However, this does not affect Gu Ji's analysis of the future trend of tropical depressions.

According to model predictions, the tropical depression landed near Bangladesh and radiated up and down to Assam in northeastern India and West Bengal in the west. It is also the main reason for the current heavy rains in Assam.

As time goes by, the tropical depression begins to deflect.

Affected by the high mountains on the mainland, the low-pressure belt in Assam gradually weakened, and the precipitation was expected to disappear completely in two days. But what he did not expect was that the tropical depression that had lost its "right arm" would return to the Bay of Bengal during the deflection process, and again

It accumulates strength on the sea surface and has the potential to evolve into a tropical storm.

Tropical storms belong to the second level of the classification of tropical cyclones. They are already considered typhoons or hurricanes. Not only do they have stronger precipitation than "infant stage" tropical depressions, they also have stronger winds, which can reach 17.2 to 24.2 meters/second.

Anyone who has studied geography in high school knows that once a tropical cyclone makes landfall, it will basically weaken quickly or even disappear.

On the one hand, this is because the typhoon loses sufficient water vapor supply from the ocean after it makes landfall; on the other hand, there are too many obstacles on the land, undulations, and high friction, which will quickly lose the typhoon's energy.

But there are some more special examples.

For example, Yutu, the famous "King of Typhoons", weakened after hitting Saipan in the United States, and then significantly strengthened again, returning to the throne of Category 17 typhoons. The main reason was the phenomenon of "eyewall replacement". As long as the eye reorganization is completed, After the new eye is constructed, the typhoon will intensify significantly.

This is exactly what the tropical depression in the Bay of Bengal is doing right now.

Based on weather forecasts, Gu Ji calculated that the re-intensified tropical storm is likely to hit West Bengal.

This is also consistent with his initial inference.

Assam is backed by the Himalayas and has many mountains that easily consume cyclone energy. However, Assam is located in the Ganges Delta, the world's largest, and its terrain is flat. It cannot stop the strong winds and rains of tropical storms. Hurricane disasters in the United States are far more serious than in other countries. Because of this, there are no mountains blocking the central Great Plains.

Gu Ji seemed to have thought of something and hurriedly called up the satellite map on his mobile phone.

However, due to poor signal and heavy rain, he spent a lot of effort to find the topographic map of West Bengal. According to the topography, it is divided into two parts. The northern part has the high-rise Teesta River, and the Tol The Star River, the Ranjit River and the Mahananda River, and the southern region has the Ganges, Hooghly, Rupunararam and Damodar rivers.

This is enough to prove that the water resources of West Bengal are no worse than those of Assam, or even better.

Especially in the northern region, hundreds of large and small dams have been built on many rivers. According to the routine of urgent agricultural irrigation in the delta plain in autumn and winter, they must be full of water. If a tropical storm lands and the dams break, West Bengal will There will be floods worse than those in Assam!

West Bengal has a population of 100 million, three times that of Assam!

Among them is the third largest city in India:

Calcutta!

Just when Gu Ji was caught in a huge whirlpool of crisis, the rescue boat team finally reached the edge of the land safely. Although there was still water here, due to the obstacles of hills, the water could only touch the ankles.

It was already past one o'clock in the middle of the night.

It is hard to imagine that they were hit by floods starting at 9:30 and were trapped alive in the train for nearly four hours.

I have to lament that human survival instinct is really a miracle.

The victims jumped out of the boats with joy and rushed to the nearest disaster evacuation center on foot according to the arrangements of the soldiers, while some old, weak, sick and disabled people were taken away directly by transport vehicles sent by the army.

"Great, Vidi, we are setting foot on this land again!"

Fatima was about to share the joy of surviving the disaster with Gu Ji, but the other party just lowered his head with a solemn expression and did not respond, "Vidi, Vidi! Why don't you seem unhappy? What happened? What?"

"Fatima, this flood disaster is far from over. We must quickly find Minister Anurag and the Meteorological Bureau."

Gu Ji cannot yet state clearly that the tropical storm will hit West Bengal, because in the eyes of outsiders, he has no access to data from the Indian Naval Meteorological Center, and naturally has no basic evidence to support his argument.

The disaster evacuation centers supported by the central government are much more organized than before.

Looking around, in addition to the densely packed tents, there are also specially set up material centers and command centers. The materials include tents, blankets, clothing, medicines and the most important food, mainly rice and noodles.

Senior officials of the state government had already come out of the tent at the command center to greet the victims and express condolences to the victims.

Gu and Ji hurried through the crowd and found Anurag.

"Thank you to Lord Shiva for blessing, you two finally came back safe and sound."

Anurag couldn't help but feel excited when he saw the two of them. One was his most proud subordinate, and the other was a talent with unlimited potential that he had just recruited. He would have been reluctant to let go of anyone else, "If I had known, I wouldn't have let you go.

The car is under escort!"

"Minister, you should be grateful for sending the two of us on the train. Otherwise, without Vidi here, what will be the final outcome of this train? I'm afraid..."

Fatima did not tell everything, but everyone knew that the successful rescue of these victims was all thanks to Gu Ji!

But Gu Ji himself was not immersed in the flattery, but asked with a serious face: "Minister, what is the real cause of the sudden flood in Assam this time? Was it because the dam's water storage exceeded the standard, causing the embankment to burst?

"

This is the answer Gu Ji wants to know most right now.

If this is the reason, West Bengal will surely repeat the same mistake.

I just didn't expect it.
