UAE uses innovative ground-based seeding solution to generate rain

Last update: 19/09/2019
KUALA LUMPUR, Sept 19 -- The United Arab Emirates (UAE) has started to use ground-based seeding generators, which is a new and alternative method of enhancing rain in the country.

The environmentally-friendly method, which is carried out with the help of special aircrafts, is used by UAE's National Centre of Meteorology to complement the traditional method of cloud seeding.

According to the centre’s Head of Cloud Seeding Section Khalid Alobeidli, the operations are carried out by fitting these generators with 48 special flares that are loaded with salt crystals which are later fired into convective, or warm clouds accompanied with updraft or rising current of air.

"The updraft then sucks up the salt crystals into the clouds and the salts attract tiny water droplets and collide with others to enhance the coalescence process, which accelerates the growth of water droplets in the clouds into bigger droplets that eventually lead to rainfall,” said Alobeidli as quoted by the Emirates News Agency (WAM) on Wednesday.

These generators are solely controlled from the operating room at the National Centre of Meteorology, Alobeidli added.

He said the rain enhancement attempts to extract as much water from the clouds as possible, which reaches more than 25 per cent in some cases.

The report added that the technology is part of the country’s continuous efforts to seek innovative solutions for rain enhancement programmes in order to boost water security in the country.

It added that some 150 cloud seeding aircraft operations had been carried out so far this year.
