Furthering Rain Enhancement Science with the 5th Cycle Grant Awards: Interview with Alya Al Mazroui, Director of UAEREP

The UAE Research Program for Rain Enhancement Science (UAEREP) recently hosted their 5th Cycle Awards Ceremony, awarding three new teams on their unique projects in the rain enhancement sciences. Why do you believe it’s important to invest in this field? Rain enhancement presents a promising opportunity to diversify water resources and reduce dependence on traditional water supplies. In the face of a rapidly growing population that places increasing pressure on water resources,Read more...

Uncrewed Aircraft System Demonstration to Identify Seedable Regions for Precipitation Enhancement

Cloud seeding operations can be made more effective by improving the operational targeting of seeding material. However, a key challenge when attempting to improve the effectiveness of cloud seeding through the current standard practice involves identifying and utilizing sub-cloud features in real-time to deliver the seeding material to the right time and location within the identified cloud. Overcoming this challenge is crucial for maximizing the operational and outreach benefits of cloudRead more...

National Center of Meteorology Hosts Successful 6th Edition of International Rain Enhancement Forum

Under the patronage of His Highness Sheikh Mansour Bin Zayed Al Nahyan, Deputy Prime Minister and Minister of Presidential Court, the National Center of Meteorology (NCM), through the UAE Research Program for Rain Enhancement Science (UAEREP) hosted a highly successful sixth edition of the International Rain Enhancement Forum (IREF) from 24 to 26, January 2023. Organized as a biennial forum, IREF provides a global platform for discussion of the latest developments and efforts to findRead more...

Study Uses Large-eddy Simulation to Demonstrate Importance of Mixed-phase Processes for Rain Enhancement in UAE

Cloud seeding aims to accelerate the hydrometeor growth and consequently convert water contained inside clouds to snow or rainfall more efficiently than it would naturally. Due to its importance in tackling water scarcity, seeding clouds by the release of hygroscopic or glaciogenic aerosol particles in convective clouds to enhance precipitation has received increasing scientific as well as commercial interest. While glaciogenic seeding in orographic clouds has consistently shown positiveRead more...

Study Uses Doppler Lidar and Cloud Radar to Observe Pre-convective Environment and Convection Initiation in UAE’s Al Hajar Mountains

With an annual precipitation ranging from 20–40mm to 140–150 mm, the UAE is one of the driest countries in the Middle East, making it highly vulnerable to climate change impacts in the future like the rest of the region. Furthermore, the UAE’s precipitation trends are projected to decrease by 20% by the year 2050 and 45% by 2100, compared to the period 1961 to 1990. This has prompted the UAE Research Program for Rain Enhancement Science (UAEREP) to fund a project titledRead more...

Study Investigates Role of Electrostatic Attraction Between Drops in Rain Formation

Aerosol particles play a central role in cloud microphysics and hence in the formation of precipitation. In warm clouds, the process of precipitation formation begins with the nucleation of cloud droplets on aerosol particles. Many studies have explored the possibility of sending an electric charge into aerosol particles to induce precipitation. Such methods can potentially help countries like the UAE reduce the risk of water stress given the high levels of dust andRead more...

Study Investigates Evolution of Drop Size Distributions in High-based Cumulus Congestus Clouds over the UAE

‘Warm rain’ generation, a process that does not involve an ice phase, depends on the characteristics of the cloud Droplet Size Distribution (DSD). Observations show that the formation of warm rain requires large droplets with a radius exceeding 12 - 14 micrometers prior to the development of warm rain. Another key factor in warm rain formation is the width of DSD, as wide DSDs promote the growth of drizzle-sized drops through collision-coalescence. To better understand DSDRead more...

Study Uses New Dataset to Investigate Desert Precipitation

Precipitation generation requires a combination of conditions such as moisture availability, cloud processes that can grow droplets to large sizes, and conditions in which droplets can reach the surface without evaporating. Understanding the details of rainfall generation in these conditions is important for weather forecasting and for the evaluation of artificial interventions to increase rainfall. Despite the presence of rain-bearing clouds, surface-reaching rainfall amounts remain scarceRead more...
