The Hot Summer Months Are ACTUALLY Really Good For Dubai’s Cloud Seeding Plans
You’re probably thinking summer and good do NOT go together. Well, they do. And it’sĀ for good reason. This season is best for harvesting rain in the UAE, and theĀ National Centre for Meteorology and Seismology runs cloud seeding flights four days per week. A number that’s higher than what it does in winter months.
If you don’t know much about cloud seeding…
It is basically a form of weather modification. The idea is to change the amount or type of precipitation that falls from clouds (increase rain or snow). This is done by dispersing substances into the air that serve as cloud condensation, and theyĀ alter the microphysical processes within the cloud.
UAE started cloud seeding in the 1990s
It generally happens in the mountainous areas in the north of the country. The government is looking into cloud seeding as an alternative to desalination plantsĀ which are harmful to the environment and expensive. Though, currently these plants are becoming the major source ofĀ water in the UAE.
So why is summer a good time for this?
Sufian Farrah, meteorologist and cloud seeding expert at the centre, explains, “It’s because in summer months the monsoon drafts, which traps moisture into the atmosphere”.
How does the process work?
The centre has set upĀ 74 automatic weather stations across the country. They measure the elements that are important to cloud seeding –Ā weather conditions, atmospheric pressure, wind direction and speed and global solar radiation. Plus they haveĀ a second generation satellite that watches and monitors the region’s air mass, fog, storms and thunderstorms.Ā
Once a ‘good’ cloud is found, theirĀ Beach Craft King Air C 90 airplaneĀ is sent out to seed the cloud,Ā where the pilot releases flares at its base containing salts. In 15-20 minutes, the reaction to the salts is produced and it starts to rain.

The results
Since its start 16 years ago, dusty areas have seen an increase of rainfall byĀ 10 to 15%. On the other hand cleaner areasĀ have seen an increaseĀ of rainfall from cloud seeding by 30 to 35%.
