Under the patronage of His Highness Sheikh Mansour bin Zayed Al Nahyan, UAE Deputy Prime Minister and Minister of Presidential Affairs, the UAE Research Program for Rain Enhancement Science today hosted a special ceremony at the UAE pavilion at Expo 2020 Dubai to honour the winners of its fourth cycle grant.


Under the Patronage of His Highness Sheikh Mansour Bin Zayed Al Nahyan, Deputy Prime Minister and Minister of Presidential Affairs, we are cordially inviting you to attend the UAE Research Program for Rain Enhancement Science Fourth Cycle Award Ceremony taking place on the 13th of January 2022 in the UAE Pavilion during EXPO 2020.


The National Center of Meteorology (NCM), through the UAE Research Program for Rain Enhancement Science (UAEREP), hosted an expert-led panel discussion at the UAE pavilion in 26th UN Climate Change Conference of Parties (COP26) currently underway in Glasgow, Scotland to highlight the UAE’s achievements in rain enhancement research and its application.


The National Center of Meteorology (NCM), through the UAE Research Program for Rain Enhancement Science (UAEREP), has carried out a research campaign in Colorado, United States of America to investigate the possibility of using autonomous unmanned aircraft systems to collect cloud microphysical measurements and provide automated cloud seeding decisions.

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...

National Center of Meteorology Participates in WETEX 2021

Abu Dhabi-UAE: 5 October, 2021 – The National Center of Meteorology (NCM) announced its participation in the 23rd edition of Water, Energy, Environment Technology Exhibition (WETEX) 2021, which is running from 5 to 7 October, 2021 at the venue of Expo 2020 Dubai. Showcasing the Center’s key achievements and the latest technologies in rain enhancement science and research, the NCM pavilion at WETEX will provide visitors with an overview of the nine research projects receivedRead more...

Study Uses Hybrid Bin Microphysics Parcel Model to Investigate Impact of Hygroscopic Seeding on Precipitation Formation

Hygroscopic seeding accelerates precipitation formation by suppressing the activation of the natural, less hygroscopic particles, and or by promoting the formation of larger water drops directly. The seeding particles become activated at lower supersaturation due to their higher hygroscopicity and larger size compared to background cloud condensation nuclei (CCN). Different techniques are used to estimate the droplet spectra just after the activation. In most bin microphysical models, onlyRead more...

Study Applies Customized Non-Hydrostatic Model to Simulate Cloud-Precipitation Processes over the UAE

As part of its continued efforts to promote scientific advancement and new technologies in rain enhancement, the UAE Research Program for Rain Enhancement Science (UAEREP) supported a project titled ‘Advanced Study on Precipitation Enhancement in Arid and Semi-Arid Regions’, undertaken by Professor Masataka Murakami, a First Cycle Awardee of the program, and a scientist at Japan’s Meteorological Research Institute. The project applied the cloudRead more...
