Dubai is making its own fake rain to beat 122°F heat

This is actually the reason why Miami is one of the few major American cities that's never broken 100 F in recorded history. When temperatures rise significantly above 90, then the chance of rain goes to 100%, which cools things back down. It's pretty much why you get clockwork torrential downpours every afternoon in Florida summers.

Are there any known side-effects of inducing rain in an unusual place like this? The weather is a complex system, so I hesitate to speculate too much, but would it reduce rainfall elsewhere?<p>With geopolitical tensions rising over rights to the Nile, I wonder if rainfall patterns could follow a similar trend.

This is just cloud seeding. They’ve been doing it for decades, though not with drones.

&gt; The enhanced rain is created using drone technology that unleashes electrical charges into clouds in order for them to clump together and form precipitation...Applying electrical shocks to clouds is preferred as it doesn’t require the use of chemicals.<p>Sounds pretty innocuous. I&#x27;m looking forward to reading comments about how this is dangerous and could cause unintended consequences. Only thing I can think of is perhaps that could reduce rainfall in neighboring areas which would have received the rain.

Evaporative cooling for the win.<p>I wish (any) parks had this built in (ignoring splash&#x2F;water parks), because it would be easier justifying brining kids out in this type of heat (especially for parks with no shade due to poor design).<p>It would also bring more community together to have outdoor areas that are dramatically cooler than the surroundings.

I&#x27;m surprised they get even 4 inches of rain a year, but it seems like it&#x27;s almost all in the winter. Assuming they can get another 4 inches during the summer, they can get as much rain as Phoenix. I wonder if this can dramatically change the landscape.

&gt; electrical charges into clouds in order for them to clump together and form precipitation<p>So like … real rain?

Question! Is there any reason this technique could not be applied to solve the Oregon wildfires?

The other comments here talk about hoarding potential for rain in the future and depriving others of it but what about weaponising it? You could potentially annihilate your enemy by generating masses of rainfall and destroying their infrastructure could you not?<p>It wouldn&#x27;t be as targetted as a missile strike but you could easily say &quot;it wasn&#x27;t me!&quot;...

I got interested in drone tech and this source has more info: <a href="https:&#x2F;&#x2F;edition.cnn.com&#x2F;2021&#x2F;05&#x2F;27&#x2F;middleeast&#x2F;clouds-electricity-rain-spc-intl&#x2F;index.html" rel="nofollow">https:&#x2F;&#x2F;edition.cnn.com&#x2F;2021&#x2F;05&#x2F;27&#x2F;middleeast&#x2F;clouds-electri...</a>

Could this be used in California as an additional fire extinguishing method?

&gt; The monsoon-like downpour drenches a busy highway,<p>Why is the word monsoon used for countries in the east and heavy rainfall or other words in the west? Is there a scientific difference?

I have read that they are using drone technology to create precipitation. Can the same method be applied in extinguishing forest fires?

so now we&#x27;re saying weather control&#x2F;manipulation is real then?<p>i guess the conspiracy nuts were right again.

Subject reminds me of this short sci-fi animation I saw somewhat recently, worth the 10 minutes imho.<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=uWCGK4nneeU" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=uWCGK4nneeU</a>

I&#x27;m curious how places out there by the sea like Dubai are essentially a desert. Evaporation should be massive at those areas no?

aka cloud seeding, a lot of country does this<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Cloud_seeding" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Cloud_seeding</a>
