Technology & Innovation

Recent rainfall across Al Ain, Ras Al Khaimah, and eastern UAE wasn't just fortuitous, it resulted from a highly sophisticated cloud-seeding operation led by the National Centre of Meteorology (NCM).

How It Works:

Cloud seeding enhances a cloud’s ability to produce rain or snow by introducing condensation or ice nuclei, tiny particles that encourage moisture to coalesce into heavier droplets that eventually fall as precipitation. In the UAE, NCM leverages advanced monitoring systems, radars, ground stations, and satellite data, along with live feeds from 26 camera sites, to forecast and detect clouds best suited for seeding.

From there, specially equipped aircraft take over. These planes briefly circle the target cloud formation; typically over a three-hour mission, and release flares containing hygroscopic agents such as magnesium, sodium chloride, and potassium chloride. A single flight may deploy around 48 flares. These flares absorb moisture and help small cloud droplets merge into heavier rain droplets.

Why It’s Effective (and Safe):

Targeting convective clouds (those pop-up, fluffy formations) yields the best results, as these clouds already carry moisture and rising energy, which seeding enhances. NCM has conducted thousands of such missions over the past decade, with aircraft deploying seeding materials whenever suitable clouds emerge. Critically, the amount of salt used is negligible compared to the natural mineral content of the atmosphere. Experts assert there are no harmful side effects from the minimal quantities released during flights.

A Leader in Cloud-Seeding Innovation:

The UAE is at the forefront of rain-enhancement research, using both traditional salt flares and groundbreaking nanotechnology inspired by international collaborations. This adoption of research-driven methods positions the country as a global hub for weather modification science.
