Is artificial rain behind UAE’s rare torrential weather? Dubai, renowned for its relentless heat and minimal precipitation, experienced an extraordinary event on Tuesday when heavy rain caused widespread flooding throughout the desert nation.
This unexpected downpour not only disrupted the bustling city’s usual rhythm but also sparked concerns about the increasing impact of climate change on extreme weather events in the region.
Is artificial rain behind UAE’s rare torrential weather?
The United Arab Emirates (UAE) typically receives less than 200 millimetres of rainfall annually, and its scorching temperatures, which can soar to 50 degrees Celsius in summer, put immense pressure on the country’s water resources.
The UAE heavily relies on groundwater sources, compounding the strain on its limited water supply.
Innovative Solutions: Cloud Seeding:
To tackle these challenges, the UAE has pioneered innovative solutions, including cloud seeding—a technique aimed at enhancing rainfall by introducing specific agents into clouds to stimulate precipitation.

The National Center of Meteorology (NCM) plays a critical role in monitoring atmospheric conditions and identifying suitable clouds for seeding based on precipitation patterns.
The Role of the Rain Enhancement Program:
The UAE’s Rain Enhancement Program (UAEREP), managed by the NCM, has been instrumental in advancing cloud seeding initiatives.
Collaborative scientific and technical research with renowned institutions such as the National Center for Atmospheric Research (NCAR) in the USA, Witwatersrand University in South Africa, and NASA has further bolstered the UAE’s capabilities in artificial rain generation.
Understanding Cloud Seeding Process:
Cloud seeding involves deploying specialized aircraft equipped with hygroscopic flares containing salt material components into targeted clouds.
These salt particles serve as nuclei around which water droplets condense, eventually leading to precipitation in the form of rain.
Environmental Concerns and Mitigation Measures:
Despite the potential benefits of cloud seeding, concerns have been raised about its environmental impact and the safety of the seeding agents used.
In response, the NCM has taken proactive measures to ensure the safety and sustainability of its operations. Unlike some other programs that use potentially harmful chemicals like silver iodide, the UAE’s initiative refrains from using such substances, opting instead for natural salts as seeding agents.
Future Directions: Nano Material Trials:
The NCM has developed a new seeding agent known as nano material, which consists of fine salt coated with titanium oxide.
This material is currently undergoing trials and experimentation to evaluate its effectiveness in enhancing precipitation while maintaining environmental sustainability.
Debates and Ethical Considerations:
Amidst the progress in cloud seeding technology, there are ongoing debates about the ethical implications of manipulating natural weather patterns.
Critics caution against interfering with nature, suggesting that extreme weather events like heavy rainfall and flooding could be nature’s response to human interventions in the environment.
