Rainmakers in Dubai

Not sure which forum it should go to? Not an aviation incident, but on the other hand, the jets are floating on water... well, seemingly anyway. #-o
The surreal scenes in DXB - airport flooded (video).
And there are opinions it could be their 'own making' - the 'rainmaking technology' side-effects (or after-effects), as discussed in Business Insider, Photos show Dubai overwhelmed by torrential rain — and may expose the downsides of trying to control the weather
While images of extreme flooding can show the consequences of the climate crisis, this particular event may have been worsened by a direct attempt to play rainmaker — literally.
To address water scarcity in the typically dry country, the UAE started using a practice referred to as cloud seeding in the 90s and early 2000s.
Cloud seeding is a method designed to increase the amount of water that falls from a cloud. It involves identifying suitable clouds and then using aircraft or ground-based generators to introduce a chemical agent that facilitates the production of snowflakes.
Cloud seeding has been used in countries worldwide, including in western US states dealing with drought, like California, Colorado, Nevada, Idaho, and Texas.

The practice has long been controversial, with critics dismissing it as an attempt to "play God" or being potentially harmful to the environment or public health. Scientists have not documented the harmful impacts of cloud seeding, and recent studies have suggested that the practice works.
Ahmed Habib, a specialist meteorologist, told Bloomberg that the UAE's cloud seeding operations contributed directly to the heavy rainfall that fell this week. Habib told the outlet that two planes conducted cloud seeding operations on Monday and Tuesday and that seven seeding missions had been carried out in two days.

Flight-tracking data analyzed by the AP suggested that an aircraft affiliated with the UAE's cloud-seeding project flew around the country Sunday.

More on cloud-seeding, so maybe there's something in it after all?
CNN: Dubai flooding sparks cloud seeding questions. What is it and does it work?

TV news here in South Australia showed footage of the floods and then a very brief interview with someone supposedly from the Dubai Bureau of Meteorology ( or whatever it is called there) explaining how Cloud Seeding is occasionally used and how it works.

The News footage then cut to some 'Climate Expert' in England who explained that it was all due to Climate Change and that Cloud seeding had nothing to do with it!!

I was stationed at RAF Sharjah 1963-64 when it rained for the first time in a few years complete with accompanying thunder, lightning & storm F10 winds. Lots of damage to buildings and the airfield was flooded. One bonus was the desert blooming, quite literally; an absolutely fantastic display of flowers & plants which lasted for about 12 hours or so.

Lived in four Middle Eastern countries, Qatar, Kuwait, Bahrain and Abu Dhabi for a total of seven years, it rained in every one at some time. Each time it resulted in some degree of flooding as the infrastructure was not designed to cope with any significant rain.

Hmm! Sounds like the UK.

Bahrain also flooded. When I lived there, they redid the roads in the souk. They were very proud of them and had even put a camber in the road-unfortunately, no drainage. Unless things have changed, therein lies the problem.

I remember that in Limassol (1965-67) they filled the road drains with sand during the hot summer months, can't remember how they cleared them ready for the rains

Former colleague, old gliding mate of Pinky, did a big statistical study on cloud seeding here in the early '60s. From memory, it showed an increase in rain over the area studied, but don't know if it looked at effects upwing or downwind. I presume he looked at various atmospheric conditions, but don't know for sure.

I worked for Rex Aviation in the '60s and was contracted to provide maintenance for 2 x Cessna 310 used for cloud seeding. As to the success,
the pilots would say the operation can best be described as,---- does not rain water, but rains money doing it.----

Bob, that may have been the same project - right timing. Our guy was Jan C.

Hydro, the only one I can remember from those times was one of the pilots George Martin. George was responsible for pulling off a great belly landing
at Sydney due to u/c failure, shut both engines off on approach aligned the 2 bladed props with wings usiing starter and hardly put a scratch on the A/C

Stolen from TOP
Regarding the wheels up landing by REL or REK at SY, I was the Surface Movement Controller in Sydney Tower when this occurred - in 1961 or 1962. It happened much as described. The only "damage" was scratches on the underside of the engine cowls. When the fuss was over a crane went out on the grass area to raise the aircraft, the gear was successfully lowered and locked, the engines were started and the aircraft was taxied to the apron. I think the pilots name was George Martin?

Well, some said the Dubai residents were somewhat happy about the relief from heat, too?

Funnily enough last night I was trying to recall the name of a person involved with anti-hail operations over the fields in the centre of the country. I have seen then operating and they did a great job transforming a hail front to torrential rain.

Any 'recall' on how they did it?

Jan had a scar on his lip from a forced landing, but I think it was from his time on bombers during WW II.
