The cloud masses above the Amazon rainforest contain more water than the Amazon itself. When these “flying rivers” hit the Andes they are pushed south and rain down over the cities of South America.
The Amazon rainforest is immense, stretching across several countries. Considered the green lung of the earth, it is one of the regions with the greatest biodiversity in the world.
The precious ecosystem of this forest area, which is several hundred thousand years old, plays a central role in maintaining the global climate’s delicate balance. Here, billions of trees absorb carbon dioxide and release oxygen. This ‘green ocean‘ also constitutes the world’s largest freshwater reserve.
In the future, water is expected to become scarce. It may well become as sought-after a resource as oil was in the 20th century. That’s why it’s so important to have a thorough understanding of water cycles.
Twenty years ago, Brazilian scientist Antonio D. Nobre coined the term “flying rivers” to refer to the masses of water that circulate in the rain clouds over South America. He tirelessly researched how they function and gained insights into the complex role played by the rainforest in climate regulation. His investigations focused on two major questions: Why are there no deserts in South America, while dozens of them exist at the same latitudes in Africa and Australia? And why can the winds blowing from the northern hemisphere cross the equator — which is an insurmountable barrier everywhere else on earth — here?
To find answers to these questions, Prof. Nobre investigated what’s known as the biopump theory, developed by two Russian physicists. This theory states that forests create negative pressure that draws moist air inland with great suction, which then ensures further rain. This fundamental discovery turns earlier scientific findings on their head.
The film uses 3D models, among other things, to illustrate how “flying rivers” work, and explain why they have such a major impact on the global climate.

At 36 years old does anyone else feel like every so often everything you were told by experts gets absolutely blown out of the water and something new emerges.
Strongly said: « Leave the forests alone!!! ».
Or the forests will leave you alone.
Forests can survive without us but humans can not.
Would you please translate this documentary into BENGALI? It will be very helpful to fully understand this eye-opening masterpiece for us too.😁😊
Very informative and well done documentary. Thank you DW
😂
My whole geography class passed by which I learnt as a student .. the difference was that I did not ask these questions…. This is what separates the innovator ….. beautiful documentary ….. well done team .. the hard work and research can be seen …. Mother Earth you don’t stop amazing is eternally ….
With a simple count, 1000 litres of water divided by 720 minutes of day light (only time the water circulate on the trees) and you get 1.4 litres per minute, that sound a lot off of a exact count to me. Maybe the greatest tree along a river would be able to do that so, but even that would sound a over estimation for me.
Amazon will be gone in another twenty years at the rate it is going. An unfolding disaster really but hey it's just a cycle of life..
STOP USING WOOD FOR HOUSES, ETC…ALL COUNTRIES SHOULD HELP TO PROTECT AND STOP THE USE OF THESE TREES OF THE RAIN FORESTS…🙏
Thank You Mother Earth.
Soon this vapor river will been seen in every part of earth as the result of climate changes. the gift will be given to human by mother nature.
let me shorten this trash video up. Millions of trees… yes. Billions… no. That's in the first minute of the video. As for the rest… moisture is in clouds, and brings water. Nothing new here. There ya go. Don't waste more of your time. They want commercial time for you to endure here.

If the "scientists" just looked at the steam property tables, they can answer the questions without the biopump theory.
I do these calculations every day. Not rocket science.
Thank you DW for a quality documentary 🔥
Many trees that are more than 30 years old spread roots for kilometers and kilometers. I am 61. I have seen and experienced it.
Thank you for a excellent informative documentary.

@DW Documentary : Excellent documentary and it is great that there are some scientists working on this project, rather than having only one scientist doing this ; however, the ending of the film says, " In Memory of Victor Gorshkov ", and it would be good to learn about him. I just did a search at Wikipedia and did not get any page about Victor Gorshkov, and I didn't notice anything about him in this film, only the short "In Memory of" him bit at the very end of this film.
carbon – water cycle is stored in 'carbohydrates'. also just as important is N-P-K cycles.
love the mention of the 'vertical cooling mechanism' and the bionic pump!
such a great episode!
It just shows everything great or small are all connected!
I live exactly in the middle of this "lucky quadrangle". In the middle of São Paulo State, Brazil. This year its raining almost every day since january. What just a few know is that underneath this "lucky quadrangle" is the biggest natural water revervoir of the planet ! It reaches four countries, Brazil, Argentina, Paraguay and Uruguay. Search by "aquifero guarani" (guarani aquifer).
Stop the video at 30:56 min when she says " sensors positioned all the way up the tower". You will see one of these "sensors" who protect the rainforest ! They fly against the drone ! Native tribes says the forest is protected by "souls of the forest"
97% of the oxygen on earth comes from the oceans
DW hands down the best documentaries on the internet ! Thank you for existing!
This is Amazing Research . Its likely that the Himalayan Forest in India do the same to Monsoons . Am i Right?
Wind blowing from low pressure to hight pressure could be due to interplanetary magnetic fields.

The answer to these anomalies could be – THE STATUTE OF THE CHRIST REDEEMER. Jesus says: "Come to Me and you will never thirst again". The statute is quite big and is located in Rio De Janeiro.
very informative. thanks DW Documentary
I really enjoyed this. Again we can see how nature is such a marvellous thing and we humans are the blight on it's surface. We will never save this planet because there are so many people who don't care about the consequences of their actions. Sad, very sad.
