China's largest desert: Taklimakan Desert, can it become an oasis if it rains heavily?

It took the people of China nearly half a century to turn the Mu Us Desert and Kubuqi Desert into oases of nearly 60,000 square kilometers. Of course, compared with the largest Taklimakan desert in China, it is still a drop in the bucket!

If there is heavy rain in the Taklimakan desert, such as three days and three nights, with sufficient rainfall, is it possible for the desert to become an oasis?

What will happen if it rains heavily in the desert?

"When you meet an old friend in another country, the long drought meets the rain, and the wedding night is spent." This is the three great happy events in life. Heavy rain in the desert is definitely a good thing for God. But there are not many things falling from the sky, such as hail or falling rocks, so it is basically not a good thing to have a rainstorm in the desert!

Xinhua News Agency reported on June 9th that extreme precipitation occurred in southern Xinjiang on 20 10. From the 2nd to the 9th, the precipitation in the southern margin of Taklimakan Basin and southwest Xinjiang has exceeded 50 mm, and even exceeded 100 mm in some places, all exceeding the average precipitation for many years, including 65,438 in Aksu City, Minfeng County in Hotan area, Maigaiti County and Zepu County in Kashgar area.

Hotan area belongs to desert arid or desert arid climate, and the average annual precipitation is only 35 mm, which exceeds 100 mm in a few days, which is equivalent to several years of rain. So, local people welcome nectar? But the eggs merged, the flood! Heavy rainfall has caused death in Qiemo County 1 person in southern Xinjiang, many roads have been washed away and traffic has been blocked!

So the rainstorm in desert area is not a good thing, but may lead to disaster!

Rainfall in the hinterland of arid desert is unlikely, but it does exist, except that the desert can not store water at all, which will also cause floods, disappear after being absorbed by the desert, or form oases in low-lying areas. This is entirely possible. The oasis area of the desert is a relatively high groundwater level area. If such conditions exist, it is still possible to form several regional oases in the Taklimakan desert!

What is the fate of Aier Lake, the largest desert lake in the world?

In fact, there is no need to assume that the climate will change after the heavy rain in the Taklimakan desert, because there is really a lake on the earth that will pop up every few years, and that is Lake Ayr!

Location of Lake Aier, Australia

Lake Aier is a seasonal lake located in the desert of central Australia. The lake is below sea level12m. The precipitation here is less than 120mm, but the evaporation is more than 2500mm, so the Cooper Creek and warburton River injected into Aier Lake evaporate completely in the dry season, and there is no water in Aier Lake, so Aier Lake often dries up!

It will be filled every few years and submerged every few decades. In the past hundred years, there have been four relatively large floods, with the largest area exceeding 8200 square kilometers and the minimum precipitation being 0 square kilometers!

When the lake dries up, it is a salt field.

The creatures in Lake Aier are really miserable. They died of drought and waterlogging, so the fish and shrimp there have a special ability to produce seeds and ensure the reproduction of future generations. Their eggs can be preserved in the arid desert for several years, and then hatch when the next rain fills the lake in a few days, and then become a paradise for all kinds of birds!

However, the existence of Lake Aier did not permanently change the climate of the desert in central Australia. Otherwise, how can there be only four floods in this hundred years? The key is the continuous input of water vapor. It's no use relying on the river alone. Excessive evaporation will change everything, and the lake will eventually dry up, leaving a shiny salt shell!

The result of heavy rain in Taklimakan desert

So after the rainstorm, there will be lakes in the Taklimakan desert, but nothing will change. Of course, we have been saying that the result is not important, but the process! Indeed, a rainstorm can greatly change the Taklimakan desert. Before the lake dries up, all kinds of plant seeds left in the surrounding wet area will germinate quickly and then spread into a green sea of flowers!

Then these flowers will bloom and bear seeds in about two weeks, and then fall into the cracks in the sand, expecting the next rain. Maybe they have been waiting for this germination for hundreds or thousands of years, and plant seeds can be preserved for a long time under suitable conditions!

So the flower sea will appear in the desert of South America after an abnormal rainstorm. They have been here, they have been brilliant, and they have left seeds. For life, this is a reincarnation!

The Taklimakan desert will return to the past hot and desolate, because there is no benign water vapor input source and it has been controlled by the dry westerly belt. After the water evaporates, it will return to loneliness!
