Dubai Floods: Is artificial rain behind UAE's rare torrential weather?

Dubai, known for its arid climate and blistering temperatures, was battered by torrential rain on Tuesday, triggering widespread flooding throughout the desert nation. The unforeseen downpour not only halted the bustling city's usual pace but also sparked worries about the escalating influence of climate change on extreme weather phenomena in the area. Authorities have also reported at least one fatality and significant damage to home and businesses.

Following the intense thunderstorms that swept across the United Arab Emirates on Tuesday, Dubai experienced significant flooding, with the desert city-state receiving over a year and a half's worth of rainfall in just a few hours. The storm, which intensified around 9 am on Tuesday, caused disruption to major highways and operations at Dubai International Airport, one of the world's busiest airports for international travel.

Inside the terminal, the scenes were chaotic, with reports of families stranded and some people being turned away due to overcrowding. Witnesses described the flooding as reaching 'Biblical levels,' with more than 4.7 inches of rain falling before 4 pm, matching the typical yearly average. Roads around the airport were submerged, and wealthy drivers in luxury cars were seen 'floating' through the flooded streets.


Meteorological reports indicate that approximately 20 millimeters (0.79 inches) of rain drenched Dubai late Monday, with the city accumulating more than 142 millimeters (5.59 inches) of rain by the end of the day. This amount far exceeds Dubai's average annual rainfall of 94.7 millimeters (3.73 inches) at its international airport.

Understanding Cloud Seeding
Cloud seeding is a technique that involves introducing "seeding agents" into clouds to stimulate the condensation process and trigger rainfall. The process begins with weather forecasters at the NCM monitoring atmospheric conditions and identifying suitable clouds for seeding based on precipitation patterns.

The UAE first tested cloud seeding in 1982. By the early 2000s, the Gulf nation's artificial rain program had been bolstered by collaborative scientific and technical research with the National Center for Atmospheric Research (NCAR) in Colorado, USA, Witwatersrand University in South Africa, and NASA.


The UAE's Rain Enhancement Program (UAEREP)
Managed by the Emirates' National Centre of Meteorology (NCM), UAEREP spearheads the program. The scientists behind this program focused on analyzing the physical and chemical characteristics of the UAE's atmosphere, particularly aerosols and pollutants, and their influence on cloud formation. The aim was to identify an effective agent to stimulate cloud growth and ultimately augment rainfall.

"The NCM has established a national network of 86 automatic weather stations (AWOS) for weather monitoring, six weather radars covering the entire UAE, and one upper air station. The Centre has also created climate databases and assisted in the development of high precision Numerical Weather Predictions and simulation software in the UAE," the UAEREP's description of the process reads.

"At present, the NCM operates four Beechcraft King Air C90 aircraft from Al Ain Airport equipped with the latest technologies and devices employed for cloud seeding and atmospheric research."


Environmental Concerns
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 measures to ensure the safety and sustainability of its operations.

Unlike some other countries' cloud seeding programs that utilize silver iodide, a crystal-like material that has raised environmental concerns, the UAE's program refrains from using harmful chemicals. Instead, it employs natural salts as seeding agents.

The UAE's innovative approach to combat its water crisis through cloud seeding demonstrates its commitment to finding sustainable solutions to environmental challenges. As the effects of climate change become increasingly pronounced, initiatives like UAEREP serve as examples of proactive measures that nations can take to mitigate the impact of extreme weather events.
