Abu Dhabi-UAE: The National Meteorological Center (NCM), through the United Arab Emirates Research Program for Rain Enhancement Science (UAEREP), has successfully completed the second phase of demonstration trials of innovative technologies aimed at to explore the possibility of artificial cloud formation by stimulating local updrafts.

The field trials were conducted at the Jebel Jeis in Ras Al Khaimah, United Arab Emirates, by a research team led by Dr. Ali Abshaev, UAEREP postgraduate and senior researcher at the Center for Research on hail suppression in Russia, to observe local-scale winter cloud processes and precipitation over the eastern regions of the United Arab Emirates and compare the results with their previous spring tests conducted from February 17 to March 26, 2021.

The goal of this project is to investigate the possibility of stimulating cumulus formation using an innovative jet engine composite system that releases a high-velocity stream of custom aerosol particles into the atmosphere to trigger artificial updrafts and, consequently, the formation of clouds.

From December 24, 2021 to January 5, 2022, the team conducted a total of twelve experiments under different atmospheric conditions. These included three experiments under clear, cloudless sky conditions, four experiments when convective or layered convective clouds were above the site or a short distance away, three experiments with direct cloud interventions convective and two experiments with interventions in stratiform clouds.

A techno-economic study to scale up the jet engine system to amplify its effects is the primary concern for future work, including more powerful jet engines (or a network of).

His Excellency Dr. Abdulla Al Mandous, Director General of the National Meteorological Center (NCM) and President of Regional Association II (Asia), said: “As part of his support to the National Innovation Strategy of the Arab Emirates United, the NCM continues to drive innovation. in research on improving rain to meet the aspirations of our wise leadership to ensure water security in the United Arab Emirates and beyond. As part of the UAE Research Program for Rain Enhancement Science, the Center works closely with program winners and supports their innovative research to find sustainable water solutions for the benefit communities threatened by water scarcity. Such efforts contribute greatly to building local and global capacity in this important area of ​​research while ensuring a sustainable supply of clean water necessary for our socio-economic development.

For her part, Alya Al Mazroui, Director of the UAE Research Program for Rain Enhancement Science, said: “Results from this project have the potential to advance our understanding of cloud formation. and precipitation development by bringing new insights to the science of rain enhancement. The atmospheric data collected during this campaign answers many important questions about cloud formation and will help us determine the optimal conditions for our future rain enhancement operations. We look forward to using the results of these studies to develop more viable and cost-effective cloud seeding methods that will ultimately increase our precipitation rates and improve freshwater supplies.

As the culmination of three years of theoretical, laboratory-scale and numerical modeling work carried out by the project team, Phase 1 of the field campaign was successfully completed last year in Jebel Jais. , Ras Al Khaimah – the highest peak in the United Arab Emirates at 1,934 meters above sea level. The campaign deployed and tested an innovative composite jet engine system, in addition to advanced scientific measuring instruments, including a bespoke weather drone, microwave radiometer, wind lidar, fog cannon, and thermal infrared imager, among others.

The project draws its theoretical basis from ash clouds from volcanic activity which can produce convective clouds leading to the formation of cumulus and cumulonimbus clouds which could then lead to precipitation. It attempts to recreate this phenomenon of stimulating cloud formation using more sustainable methods and available technology.
