Boosting Rainfall: New Technologies' Promise
Rainfall Could Increase by 25% With New Technologies
Research into artificially increasing rainfall in the United Arab Emirates (UAE) has reached new heights after the UAE Research Program for Rain Enhancement Science (UAEREP) officially launched its sixth application cycle. Winning projects could receive up to 5.511 million dirhams in support, with new technologies potentially increasing rainfall amounts by as much as 25%.
How can the amount of rainfall be increased?
According to the director of UAEREP, research shows that under the right atmospheric conditions, rainfall amounts can be increased by 10-25% using new procedures. The new technologies work most effectively in clearer atmospheres using advanced materials and more precise techniques.
This was discussed at the 7th International Rain Enhancement Forum (IREF) held in Abu Dhabi, one of the most important professional events on global water security and artificial rain induction.
The sixth research cycle and supported areas
UAEREP's sixth research cycle focuses on the following five key areas:
1. Optimized seeding materials – new, more effective compounds for cloud seeding.
2. Innovative systems for cloud formation and rainfall enhancement.
3. Unmanned Aerial Systems (UAS) – development of autonomous drones and flight devices to increase process efficiency.
4. Region-specific climate interventions – technologies that consider the specific characteristics of a given region.
5. Advanced modeling and data processing solutions – application of artificial intelligence and big data analytics.
Winning projects can receive up to $1.5 million in funding, encouraging innovation in this crucial area.
Nanotechnology and 300% growth in large water droplet size
Currently, the country uses nanotechnology-based cloud seeding materials, which represent a significant advance over traditional methods. These new materials are exclusively produced at the UAE's National Center of Meteorology (NCM) weather modification plant, leading to a 300% increase in large water droplet amounts compared to traditional technologies.
Central to these developments are nanoscale materials based on titanium dioxide, which improve the efficiency of precipitation formation at a 10% concentration. While earlier materials operated with combustion-based flares, the new nanotechnological material is present in a fine powder form applied in doses of just 250 grams, offering a more efficient and sustainable method.
Why is artificial rainfall becoming more popular?
In recent years, more experts and decision-makers have turned toward cloud seeding, as securing water resources has become crucial, especially in the Middle East and North Africa. According to Mohammed Mahmoud, director-general of the Climate and Water Initiative (CWI), given the increasing demand for water, every possible solution must be considered.
"The world – and especially this region – are desperately searching for ways to secure their water resources, be it for drinking, agricultural irrigation, or industrial use. Even energy production requires water use, so any technology that can help expand water supply is of paramount importance," Mahmoud stated.
Global water security and sustainable rainfall enhancement
The UAE government has set a long-term goal to support global water security by developing sustainable rainfall enhancement methods. UAEREP plays a significant role not only locally but also internationally in addressing water scarcity, seeking scientifically-backed solutions that are applicable in the long term.
Currently, the NCM's permanent meteorological unit carries out cloud seeding operations, which do not use harmful chemicals. Through innovations, the Emirates continuously improve the technology to achieve the greatest efficiency with the least environmental impact.
International recognition and future plans
According to the director-general of the NCM and president of the World Meteorological Organization (WMO), the UAE’s program has achieved outstanding results in artificial rainfall enhancement and makes a significant contribution to addressing the global water shortage.
"The leadership of the United Arab Emirates plays a huge role in making UAEREP successful. The country is committed to international research collaborations, which are recognized worldwide and are key in shaping the future of water security," he stated.
Summary
The UAE's rain enhancement program is one of the most advanced and ambitious initiatives in this area globally. With the opening of the sixth research cycle, further innovations are expected that can make artificial rainfall enhancement even more effective. The new nanotechnological materials and advanced methods could increase rainfall amounts by up to 25%, while the country's goal remains to promote global water security and apply sustainable solutions.
