Technology Bigshot Chapter 406: : Problems and how to solve them]

After coming out of the K-18 Prehistoric Biology Laboratory, everyone started to get to the point. People from the Land Administration and a large group of "national teams" came to the Matrix Technology headquarters not to visit the zoo. 〔net[(

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

In the conference room, a group of scientists, the Bureau of Land Management, Kang Tao and others were sitting on the seats, while Ren Hong was in front of a huge spotlight screen right in front of the conference. The screen displayed the topographic map of the western region of the country. The basin is in the exact center of the screen.

"About the project of transforming this second largest mobile desert in the world." Ren Hong looked at everyone, he looked back at the screen, and said, "We have to start from the climate aspect, the Tarim Basin is a typical monsoon. Sexual climate, drought!"

"If you want to transform, you must first start from the root cause. The Taklimakan Desert has accumulated sand in the Baiji era, and it evolved into today's large desert in the Cenozoic. The typical reason is the topography of the western region of our country. Structure, the Tarim Basin is surrounded by mountains, with the Tianshan Mountains in the north and the Pamir Plateau in the west. The most important thing is the dual isolation of the high-altitude Himalayas and Kunlun Mountains in the south. In addition, the southeast is the highest plateau in my country and the world. Here, the water vapor from the Indian Ocean can hardly enter the Tarim Basin, the Pamir Plateau in the west blocks the humid ocean air flow, and the southeast monsoon and the southwest monsoon cannot blow into the Tarim Basin..."

Ren Hong pointed to the map and said: "And this plateau and mountain range also blocked the northward flow of the dry and hot westerly wind in Central Asia, which undoubtedly added fuel to the fire. The dry westerly wind in Central Asia cannot be dissipated here. Go, the Tarim Basin is surrounded by thousands of meters of mountains and plateaus on all sides, 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, and the dry and violent west wind in Central Asia has been controlled. This land directly led to the formation of the Taklimakan Desert.”

A meteorologist sitting at the front also began to speak, he said: "As for the water vapor transport in the southern frontier, my expedition team has conducted long-term field surveys over the years. We have obtained some results. We believe that the source of water vapor in the Taklimakan is basically formed by the weather evolution of the mainstream system of external circulation, rather than the internal circulation of the Tarim Basin. The Tarim Basin is surrounded by high mountains and plateaus. The transport of water vapor in the lower layers is very little or almost zero."

"A series of studies have shown 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 when the convective cloud moves slowly in the summer, this kind of Convection greatly increases the vertical water vapor transport. Our research shows 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 However, the humidity of the ground layer 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 listened and nodded silently, the meteorologist continued: "But it is worth mentioning that on the contrary, the middle and lower levels of the region transport a large amount of water vapor, often under the influence of the external monsoon. The horizontal output of the action, combined with the vertical convection action, theoretically, will often produce a large number of heavy rains, such as the attack of the heavy rainstorm on July 1988."

"As far as I know, that heavy rain was a special case." Ren Hong said, and then turned to expand the map to the whole of Asia. He stared at the screen and said, "The heavy rainfall in 1988 was due to the high pressure ridge in Europe. The east moves southward, and the wave trough from West Siberia to Central Asia in the north blocks the eastward movement of the vortex. In addition, due to the splitting of the subtropical high in the Iran region, the southeastern plateau is in a subtropical low wave trough. In the past, there was a period of short-term wave trough affected by it, which produced a large amount of precipitation.”

Ren Hong turned to look at the meteorologist, and then looked at the others, and said: "The water vapor transport in the Taklimakan area comes from four directions: moving, west, south, and north, among which the west and north are the main ones. In summer, the water vapor from the east and south can enter the Taklimakan area, but although the eight rainfalls were as high as 45 mm, it was just an unexpected accident.”

"It is true that the precipitation in the Taklimakan area is actually not a small number, generally around 5o to 6o mm, but it is basically located in the high mountain area, the most typical is the northern **** of the Kunlun Mountains, especially in the northern slope, and the evaporation in the desert area. It is quite large, and the water that actually falls to the ground will soon seep into the soil layer and be evaporated." He glanced back at the map and said, "Anyway, fundamentally speaking, for the Taklimakan Desert area, the The climate problem of high convection vertical transport does nothing to change the local desert climate.”

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

Ren Hong heard the words, was silent for a moment, organized the words in his mind, and then said: "The problem of rigidity in the Tarim Basin is still surrounded by mountains, which are affected by the geographical features of the high mountains and plateaus. The climate of the external circulation cannot affect the interior of the Tarim Basin. cause direct climate impacts.”

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

"A lot of things, they will disguise the way to solve them, or disguise their weaknesses as strong, so they are ignored." Ren Hong said, this sentence undoubtedly made everyone puzzled, but he did not ask, Ren Hong said. Hong obviously didn't finish his sentence. After a while, he continued: "The core factor that causes the current climate in the Taklimakan region is the cause of geographical features, and the answer to the problem is here."

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

Ren Hong looked at the map on the spotlight screen again and said, "Look at the geographical features of the Tarim Basin, surrounded by high mountains and plateaus, with the Tianshan Mountains in the north, the Pamir Plateau in the west, the Qinghai-Tibet Plateau in the southeast, and the Qinghai-Tibet Plateau in the south. There are the Himalayas and Kunlun Mountains, and the influence of the external circulation climate can be ignored, while the surrounding mountains prevent the internal air and wind from going northward. These factors allow the Tarim Basin to have the characteristics of the internal circulation climate.”

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

"Our starting point is the problem of inner loops!"
