Field trials were conducted at Jebel Jeis in Ras Al Khaimah, led by a research team led by United Arab Emirates 3rd cycle laureate Dr Ali Abshaev, senior researcher at the Russian Centre for Hail Suppression Research, to observe local-scale cloud processes and precipitation in winter . Eastern United Arab Emirates. These were then compared with the results of the spring trial conducted from February 17 to March 26 last year.
The purpose of the project is to investigate the possibility of stimulating cumulus cloud formation using an innovative jet-engine composite system that releases a tailored high-velocity stream of aerosol particles into the atmosphere to trigger artificial updrafts to form clouds.
From December 24, 2021, to January 5, 2022, the team conducted a total of 12 experiments under different atmospheric conditions. These included three experiments under clear cloudless sky conditions, four experiments with convective or stratified convective clouds over the site or at short distances, three experiments with direct intervention with convective clouds, and two with stratified clouds experiment of.
Technoeconomic research to expand jet engine systems to expand their impact is a major focus of future work, including more powerful (or networked) jet engines.
“As part of its support to the UAE’s National Innovation Strategy, NCM continues to drive innovation in stormwater enhancement research to fulfil the aspirations of our wise leadership to ensure water security in the UAE and beyond. Through UAAREP, NCM works closely with project winners Collaborate to support their pioneering research efforts to find sustainable water solutions for the benefit of communities at risk of water scarcity. These efforts go a long way in developing local and global capacity in this important area of research, while ensuring Sustainable supply of clean water for our socio-economic development,” said Dr Abdulla Al Mandous, Director Chair, NCM, Regional Association II (Asia).
“The results of this project have the potential to advance our understanding of cloud formation and precipitation development by contributing new knowledge to precipitation enhancement science. Atmospheric data collected from this event answers many important questions about cloud formation and will help We identify optimal conditions for future rain enhancement operations. We look forward to using the results of these studies to develop more feasible and cost-effective cloud seeding methods that will ultimately increase our rainfall rates and enhance freshwater supplies,” UAEREP Director Alya Al Mazroui said. added.
As the result of three years of theoretical, laboratory-scale and numerical modelling work by the project team, the first phase of the field activity was successfully completed last year in Jebel Jais, Ras Al Khaimah, an area 1,934 meters above sea level in the UAE The highest peak sea level. The event deployed and tested an innovative jet engine composite system, as well as advanced scientific measurement instruments, including custom-made weather drones, microwave radiometers, wind Lidar, fog cannons and thermal infrared imagers, among others.
The theoretical basis for the project comes from ash clouds produced by volcanic activity, which can create convective clouds that form cumulus and cumulonimbus clouds, which can then lead to precipitation. It attempts to reproduce this phenomenon that stimulates cloud formation using more sustainable methods and available technologies.
