How did Dubai ‘beat the heat’ through the use of artificial rains, read more about cloud seeding?DNA India
While the monsoon season wreaks havoc in some parts of India, Dubai has created some artificial rainfall for its own benefit. With temperatures exceeding 50 degrees, Dubai utilised the cloud seeding technique to obtain some relief.
The National Center of Meteorology (NCM) of the United Arab Emirates used drones to coerce clouds into raining. They accomplished this by electrically charging clouds. Drones are charged into the clouds during this process, causing them to clump together and precipitate.
Extreme weather is occurring in several parts of the world, including North America, Africa, Europe, and Asia. Climate change, experts say, is to blame for these conditions.
Cloud seeding: Refers to the practise of seeding clouds.
Cloud seeding is a technique for causing a cloud to rain. This technology was introduced in the late 1990s in the United Arab Emirates.
Chemicals such as silver iodide, potassium iodide, and dry ice are released into the atmosphere via planes here.
These particles attract the moisture in the air, resulting in the formation of cumulonimbus clouds and eventually rain.
This method produces rain in about a half-hour. The quickest method is to zap the top layers.
The time required to generate rain is dependent on the portion of the cloud into which the chemicals are injected.
Drones are used to induce rains in several ways.
Following the identification of cumulus clouds by experts, a drone is sent to spray water into warm clouds and drop ice into cold ones.
Drones are then flown over the cloud, spraying salt particles such as silver iodide and chloride on it.
These salt particles act as a core, drawing water vapour into clouds, where it condenses into water droplets, forming raindrops.
Dubai’s cloud seeding project began in July 2010 and is estimated to cost USD 11 million.
Negative consequences for the environment
According to scientists, this method could result in ocean acidification, ozone layer depletion, and an increase in atmospheric carbon dioxide levels.
Silver is a toxic, heavy metal that is harmful to plants, humans, and animals.
The expense of cloud seeding
Cloud seeding is also an expensive technique. A foot of rain costs approximately USD 200.
According to experts, Dubai’s recent rainfall programme could have cost between USD 27 and USD 427 per acre-foot.
Dubai may have spent Rs 4.15 crores on this fabricated rainfall.
