Chapter 406: : Problems and how to solve them]

After coming out of the K-3018 Prehistoric Biology Laboratory, everyone began to get into the subject. People from the Bureau of Land Management and a large group of "national teams" came to the Matrix Technology Headquarters instead of visiting 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 kilometer Taklimakan Desert.
In the conference room, a group of scientists, the Bureau of Land Management, Kang Tao and others sat in the seats, while Ren Hong was in front of a huge concentrating screen directly in front of the conference. The screen displayed the topographic map of the western region of the country. The Tarim Basin was on the screen. In the center.
"About the project to transform this piece of the world's second largest mobile desert." 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 with drought. !"
"If you want to transform, you must first start from the root cause. The Taklimakan Desert has accumulated sand during the Cretaceous Period, and it evolved into today's large desert in the Cenozoic. The typical reason is the topographic structure of the western region of China, 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 where China is also the highest plateau in the world. As a result, the water vapor of the Indian Ocean could hardly enter the Tarim Basin. The Pamirs in the west blocked the humid ocean currents, and the southeast and southwest monsoons could not blow into the Tarim Basin..."
Ren Hong pointed to the map and said: "And this plateau and mountains also blocked the dry and hot westerly wind in Central Asia from flowing northward. This is undoubtedly adding fuel to the fire. The dry westerly wind in Central Asia cannot disperse here. Tarim The basin is surrounded by thousands of meters of mountains and plateaus on all sides, and moist water vapor in multiple directions is blocked. The most deadly thing is that the coordinate area of ​​the Tarim Basin is not in the monsoon area. The arid and violent west wind in Central Asia has been controlling this area. The land directly led to the formation of the Taklimakan Desert."
A meteorologist at the forefront also began to speak. He said: "With regard to the problem of water vapor transport in the southern region, my team has conducted long-term field surveys over the years. After inspection and years of observation, we have concluded that We have obtained some results. We believe that the source of water vapor in Taklimakan is basically formed by the evolution of the mainstream system weather in the external cycle, rather than the internal cycle of the Tarim Basin. The Tarim Basin is surrounded by high mountains and plateaus, and the middle and low levels of water vapor transport There are very few, or almost zero."
"A series of studies have found that, relatively speaking, the vertical transportation of water vapor is very abundant. In the region where the Tarim Basin is located, the horizontal vertical transportation of the atmosphere in the middle and low-level airspace is reduced. When the convective clouds move slowly in summer, this convective effect, This greatly increases the vertical water vapor transport. Our research found that the vertical convection in the Tarim Basin is very strong, especially in summer. Unfortunately, although the vertical convection is strong, the vertical ascent is also quite strong. The ground layer humidity in the Tarim Basin is very small, so small that it can almost reach zero index, and the water vapor transport volume is indirectly reduced."
As Ren Hong nodded silently, the meteorologist continued,
But it’s worth mentioning that on the contrary, the low- and middle-level horizontal transportation in this area is very large, often due to the horizontal output of water vapor under the influence of the external monsoon. , With the effect of vertical convection, theoretically speaking, this will often produce a lot of heavy rain, such as the heavy rain on July 23, 1988."
"As far as I know, the heavy rain was a special case." Ren Hong said, turning around to expand the map to the entire Asia. He stared at the screen and said: "The large amount of precipitation produced in 1988 was due to the eastward direction of the European high pressure ridge. The trough from West Siberia to Central Asia in the north blocked the eastward movement of the low vortex. In addition, the plateau area in the southeast was in a subtropical low trough due to the split of the subtropical high in Iran. Before the low vortex invaded, there was A short period of wave trough is affected by the large amount of precipitation."
Ren Hong turned to look at the meteorologist, and then to the others, and said: "The water vapor transport in the Taklimakan area comes from the four directions of movement, west, south, and north, of which the west and the north are the main ones, and the east in summer Water vapor from and to the south can enter the Taklimakan area, but the precipitation in July of 1988, although it was as high as 45 mm, was just an unexpected accident."
"It is true that the precipitation in the Taklimakan area is actually not a small number, generally around 50 to 60 mm, but it is basically in the high mountain area. The most typical is that the northern of the Kunlun Mountain is particularly prominent, and the evaporation in the desert area is quite large. , The water that really fell to the ground soon infiltrated the soil layer and evaporated." He glanced back at the map and said: "Anyway, fundamentally speaking, for the high convection vertical in the Taklimakan Desert. The climate problem of the transportation is not helpful in changing the local desert climate."
"What is Mr. Ren's opinion on this? Or the solution?" the meteorologist asked.
Hearing this, Ren Hong was silent for a moment, organized a speech in his mind, and then said: "The problem of rigidity in the Tarim Basin is still surrounded by mountains. It is affected by the geographical features of the high mountains and plateaus. The climate of the outer cycle cannot directly affect the interior of the Tarim Basin. Climate impact."
"The way to solve the problem lies in the problem itself." Ren Hong said, which made the experts present curious.
"Many things, they will disguise the methods that can solve them, or the weaknesses as strong, and thus be ignored." Ren Hong said, this sentence undoubtedly makes everyone very puzzled~EbookFREE.me~ but there is no Asking the question, Ren Hong obviously did not finish speaking. For a moment, he continued: "The core factor that causes the current climate in the Taklimakan area is still the cause of geographical features, and the answer to the problem lies here."
"What do you say?" The meteorologist sitting in the front row was very different.
Ren Hong looked at the map on the concentrating screen again and said: "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. With the Kunlun Mountains, the influence of the external cycle climate on it can be ignored, and the surrounding mountains prevent the internal air and wind from going north. These series of factors have allowed the Tarim Basin to have the internal cycle climate characteristics."
Ren Hong looked at all humans again: "The solution to the problem is to form a relatively humid internal circulation climate in the low- and middle-level airspace of the Tarim Basin, independent of the external climate cycle, in short..."
"Our starting point is on the issue of its inner loop!"
