Technology Bigshot

After coming out of K-3018 Prehistoric Biology Laboratory, everyone also started to get down to business. People from the Bureau of Land Management and a large group of "national teams" did not come to the Matrix Technology headquarters to visit the zoo.

Half an hour later, Ren Hong arranged for everyone to come to a conference room to discuss how to transform the 330,000 square kilometers of the Taklamakan Desert.

In the conference room, a group of scientists, the Bureau of Land Management, Kang Tao and others sat on the seats, while Ren Hong was in front of a huge spotlight screen directly in front of the conference. The topographic map of the western region of the country was displayed on the screen. in the middle of .

"About the project to transform the second largest mobile desert in the world." Ren Hong looked at everyone, he looked back at the screen, and said, "We have to start with the climate. The Tarim Basin has a typical continental monsoon climate, which is arid. !"

"If you want to transform, you must first start from the root cause. The Taklamakan Desert had sand accumulation in the Cretaceous era, and it evolved into today's large desert in the Cenozoic. The typical reason is the topography of the western region of my country. Tarim The basin is surrounded by mountains, with the Tianshan Mountains in the north and the Pamirs in the west. The most important thing is the double isolation of the ultra-high Himalayas and Kunlun Mountains in the south. In addition, the southeast is the highest plateau in my country and the world. , causing the water vapor in the Indian Ocean to hardly enter the Tarim Basin, the Pamirs in the west blocked the humid ocean air flow, and the southeast monsoon and southwest monsoon could not blow into the Tarim Basin..."

Ren Hong pointed to the map and said: "And this plateau and mountains also block the dry and hot westerly wind from Central Asia from flowing northward. The basin is surrounded by thousands of meters of mountains and plateaus, and the humid water vapor in many directions is blocked. The most deadly thing is that the coordinate area of ​​the Tarim Basin is not yet in the monsoon area. The dry and violent westerly wind in Central Asia has always controlled this area. land, directly leading to the formation of the Taklimakan Desert."

A meteorologist sitting at the front also started to speak. He said: "As for the water vapor transport problem in the southern border, my investigation team has conducted long-term field investigations over the years. After investigations and observations over the years, we have concluded that Based on some results, we believe that the source of water vapor in the Taklamakan is basically formed by the weather evolution of the mainstream system of the outer circulation, rather than the inner circulation of the Tarim Basin. Very little, almost zero."

"A series of studies have found that, relatively speaking, the vertical transport of water vapor is very rich. In the area where the Tarim Basin is located, the horizontal and vertical transport of the atmosphere in the middle and lower airspace is reduced, and the convective clouds in the local area move slowly in summer. This convection effect, The vertical water vapor transport has greatly increased. Our research found that the vertical convection in the Tarim Basin is very strong, especially in summer, but unfortunately, although the vertical convection is strong, the vertical rise is also quite strong, and The ground layer humidity in the Tarim Basin is very small, so small that it can almost reach zero index, and the amount of water vapor transport is indirectly reduced."

Ren Hong nodded silently,

The meteorologist continued: "But it is worth mentioning that, on the contrary, there is a large amount of horizontal transport in the lower and middle layers of the region, which is often the horizontal output of water vapor under the influence of the external monsoon, combined with vertical convection, theoretically Generally speaking, this will often produce a large number of heavy rains, such as the one on July 23, 1988."

"As far as I know, that heavy rainstorm was a special case." Ren Hong said, then turned around and expanded the map to cover the whole of Asia. He stared at the screen and said, "The heavy rainfall in 1988 was due to the eastward direction of the European high pressure ridge." Advances to the south, and the trough from West Siberia to Central Asia in the north blocks the eastward movement of the low vortex. In addition, due to the split of the subhigh pressure in Iran, the plateau area in the southeast is in the subtropical low trough. Before the low vortex invades, there is A short-term trough under its influence produces a large amount of precipitation."

Ren Hong turned to look at the meteorologist, then at other people, and said: "The water vapor transport in the Taklamakan region comes from four directions: east, west, south, and north, of which the west and north are the main ones, while the east in summer Water vapor from the north and the south can enter the Taklamakan region, but even though the precipitation in July 1988 was as high as 45mm, it was just an unexpected accident."

"It is true that the precipitation in the Taklimakan region is actually not a minority, generally around 50 to 60 millimeters, but it is basically in the high mountain areas, the most typical one is the northern slope of Kunlun Mountains, and the evaporation in desert areas is quite large. , the water that actually falls to the ground will soon infiltrate the soil layer and be evaporated.” He glanced back at the map and said, “Anyway, fundamentally speaking, for the high convective vertical Conveying the climate problem does nothing to change the local desert climate."

"What is Mr. Ren's opinion on this? Or the solution?" asked the meteorologist.

When Ren Hong heard this, he was silent for a moment, organized his words in his mind, and then said: "The problem of the rigidity of the Tarim Basin is still surrounded by mountains, which is affected by the geographical characteristics of high mountains and plateaus. The climate of the outer circulation cannot directly affect the interior of the Tarim Basin. climate impact."

"The solution to the problem lies in the problem itself." Ren Hong said, which made all the experts present curious.

"For many things, they will ignore the solutions that can solve them, or disguise their weaknesses as strengths." Ren Hong said, this sentence undoubtedly puzzled everyone, but he did not ask questions. Ren Hong obviously did not After finishing speaking, he continued after a while: "The core factor that causes the current climate in the Taklamakan region is still the reason for the geographical features, and the answer to the problem lies here."

"How do you say that?" The meteorologist sitting in the front row was very different.

Ren Hong looked at the map on the spotlight screen again, and said: "Everyone, please look at the geographical features of the Tarim Basin. It is surrounded by high mountains and plateaus, with the Tianshan Mountains in the north, the Pamirs in the west, the Qinghai-Tibet Plateau in the southeast, and the Himalayas in the south. And the Kunlun Mountains, the impact of the external circulation climate can be ignored, and the surrounding mountains prevent the internal air and wind from going north, and this series of factors can make the Tarim Basin have the climate characteristics of the internal circulation.”

Ren Hong looked at everyone again and said: "The solution to the problem is to form a relatively humid internal circulation climate in the middle and low-level airspace of the Tarim Basin, which is independent of the external climate circulation. In short..."

"Our starting point is the issue of its internal circulation!"
