How Did Dubai Create Its Artificial Rain?

The government of Dubai has opted to regulate its scorching heat, which often surpasses 115 degrees Fahrenheit. You may have heard about the recent fake rain, sometimes known as artificial rain, in the United Arab Emirates.

The United Arab Emirates’ scientists are making it rain – artificially – by controlling the weather using electrical charges from drones and pushing rainfall across the parched nation. Meteorological officials in Ras al Khaimah and other regions of the UAE released video footage of rainfall this week.

The new cloud seeding technique can help alleviate global drought conditions. It also poses fewer environmental concerns than prior salt flare-based alternatives. Every year, the UAE receives about 4 inches of rain.

The government believes that zapping clouds to generate rain on a regular basis would help to mitigate some of the country’s annual heatwaves. According to Maarten Ambaum, a meteorologist at the University of Reading, “the water table in the UAE is quickly dropping”. “And the objective here is to try to help with the rain.”

The UAE’s National Center of Meteorology shared a post showing monsoon-like downpours across the country, creating a sheet of rain on the roadways.

Clouds store water. Unfortunately, the water does not always reach the areas on the ground where it is required. This is because the water molecules aren’t thick enough to sense Earth’s gravity when they’re spread out. When molecules clump together, more significant, heavier droplets develop. They get heavy enough to fall to the Earth as precipitation eventually.

Cloud seeding is the process of altering the structure of a cloud to enhance the likelihood of precipitation. Cloud seeding is the process of introducing tiny, ice-like particles to clouds. Generally, the particles used are Silver iodide particles. These particles provide additional condensation nuclei. In the clouds, unattached supercooled water vapor molecules condense around these particles. The condensed water vapor droplets then form a clump. This cycle repeats itself until the droplets are large enough to fall like rain!

Recent Researches on this technique to create artificial rain:

According to research from the University of Reading in the United Kingdom, scientists created the storms by employing drones to strike clouds with electricity, resulting in massive rainfall. It requires larger raindrops in hot countries because small drops evaporate before reaching the ground.

“It’s inspiring to think that the rainwater technology I witnessed today may one day help nations like the UAE that are water-scarce,” Mansoor Abulhoul remarked. He observed demonstrations of this technology during his visit to the University of Reading in May. He is the UAE’s ambassador to the United Kingdom.

During the visit, vice-chancellor Robert Van de Noort stated, “Of course, our capacity to control the weather is tiny compared to the forces of nature”. “We recognize that we, as a university, have a significant role to play in understanding and mitigating the worst consequences of climate change by collaborating with worldwide partners.”

The UAE is one of the first Gulf countries to use cloud seeding technology, according to the National Center of Meteorology. According to The Scientific American, a variant of the notion is in use in at least eight states in the western United States.
