How Did Dubai Make Fake Rain?
- Anthony Watkins
The United Arab Emirates’ (UAE) government has used a practice known as cloud seeding as part of its plan to alleviate the country’s severe water shortage. There are a few different names for cloud seeding, including “man generated precipitation,” “artificial rain creation,” and “cloud seeding.” The United Arab Emirates was one of the first nations in the Arabian Gulf area to implement cloud seeding technology, making it a pioneer in the field.
Because of the country’s severely dry environment, UAE researchers have begun to implement cloud seeding technology in an effort to alleviate the country’s severe water shortage. They do this by using weather radar to keep a constant eye on the atmosphere around the country.
It has been predicted by meteorologists and other experts that cloud seeding operations can increase rainfall by up to 30–35% in an environment with low levels of humidity, and by up to 10-15% in an atmosphere with higher levels of humidity. Because it is impossible to anticipate the long-term global repercussions of this practice, it has given rise to worries over the influence that it will have on the environment.
How is artificial rain created?
Cloud seeding is one means of modifying the weather, and the production of artificial rain is one of its many applications. The purpose of carrying out cloud seeding is to bring about a change in the amount of precipitation that is brought down by the clouds.
One method for accomplishing this goal is to release compounds into the atmosphere. Answer in its entirety: The process of changing the weather through the manipulation of clouds is called cloud seeding.
In this approach, artificial rain is generated by spraying dry ice or silver iodide aerosols into the top section of the cloud in an effort to induce precipitation and form rain. This process is also known as a cloud seeding technique. The stimulation may be accomplished with the help of an airplane and a rocket.
- Silver iodide is the material that is utilized the most frequently since it is both affordable and readily available;
- Cloud seeding is a process that may be broken down into three parts, which are as follows: Agitation is the step when the chemical is used to encourage the air mass upwind of the target site to rise and produce clouds;
This is accomplished by the application of the chemical. Condensation can occur more easily as a result of the chemical’s ability to draw moisture from the surrounding air and store it. A chemical such as calcium oxides, ammonium nitrate, chloride, calcium carbonate.
- Taking shape on the rise: This is the second stage, and in this phase, the mass of the cloud is built up by the utilization of dry ice, urea, and salts (kitchen salt) in order to raise the cloud’s density;
In the process known as “seeding,” extremely chilly chemicals are shot out of pressurized canisters at the base of the clouds in order to create water droplet beads. Last but not least, cause them to fall like rain. The following is a list of the many ways of cloud seeding: Clouds can be seeded hygroscopically.
In this technique, the salts are spread in the lowest section of the clouds by the use of flares or explosions. The molecules of salt combine with the water, which causes them to expand in size. In the process known as static cloud seeding, a chemical such as silver iodide is sprayed into the surrounding air and clouds.
The silver iodide creates a crystal structure all around it, which allows moisture to condense on it. The process of dynamic cloud seeding involves enhancing the vertical air current, which in turn causes an increase in the amount of precipitation that is extracted from the clouds.
Why does it not rain in Dubai?
In order to combat an ever hotter future, diminishing water sources, and an ever-increasing population, scientists in one Middle Eastern nation are working to make it rain. Literally. This week, authorities from the meteorological department of the United Arab Emirates published a video showing automobiles driving through a deluge in Ras al Khaimah, which is located in the north of the nation.
- The storm was caused by one of the United Arab Emirates’ most recent attempts to boost rainfall in a desert nation that only receives approximately 10 centimeters of precipitation on average each year;
In comparison, Washington, District of Columbia has received an annual average of approximately 45 inches of rain during the last ten years. According to a story in “The Independent,” scientists manufactured rainstorms by shooting drones into the clouds, which then blasted the clouds with electricity.
Researchers discovered that jolting droplets in the clouds can force them to cluster together. [Citation needed] The bigger raindrops that are produced as a consequence then fall to the ground rather than melting in midair, which is often what happens to the smaller droplets in the United Arab Emirates because of the high temperatures and dense cloud cover.
Meteorologist and researcher Keri Nicoll told CNN in May as her team prepared to begin testing the drones near Dubai, “What we are trying to do is make the droplets inside the clouds large enough so that when they fall out of the cloud, they survive down to the surface.” This was said as the team was getting ready to begin testing the drones.
Nicoll is a member of a group of researchers from the University of Reading in England whose work was responsible for the artificial rainstorms that have occurred in the last week. The United Arab Emirates Research Program for Rain Enhancement Science provided the university’s researchers with 1.5 million dollars in 2017 to be used over the course of three years.
This program has funded at least nine separate research endeavors over the course of the previous five years. Nicoll and her colleagues created four drones with wingspans of around 6 and a half feet so that they could test their study. According to CNN, the drones have a flight time of around forty minutes and can be launched using a catapult.
The sensors on the drone detect the temperature, humidity, and electrical charge within a cloud as it is in flight. This provides the researchers with the information necessary to determine when and where they need to zap.
There is a significant problem with water in the UAE. According to the CIA, although the nation consumes over 4 billion cubic meters of it annually, it only has access to approximately 4% of that amount in the form of renewable water resources. According to the government’s report titled “State of Environment” from 2015, the number of people living in the United Arab Emirates (UAE) has skyrocketed in recent years, doubling to 8.
- 3 million between 2005 and 2010;
- This helps explain why demand for water spiked by a third around that time, as it was stated in the report;
- The population continued to increase during the subsequent decade and is presently estimated to be 9.9 million;
According to a statement made by Maarten Ambaum, a professor at the University of Reading and a meteorologist, who was quoted by BBC News, “the water table is lowering severely in [the] UAE,” and “the goal of this [project] is to attempt to help with rainfall.” In the UAE, rainfall is typically limited to just a few days spread out over the whole year.
- The summer months see very little in the way of precipitation;
- Recently, temperatures there reached 125 degrees or more;
- In recent years, the United Arab Emirates has made a significant investment in desalination technology, which converts salty seawater into potable freshwater by removing the salt from the water;
This has assisted in bringing the supply of water closer to the level of demand for it. According to the government of the UAE, the country’s approximately 70 desalination facilities provide the majority of the country’s potable water as well as 42 percent of the country’s total water use.
- Despite this, one of the goals of the government’s “water security policy” is to reduce the demand for water by 21% over the next 15 years;
- There has been no shortage of creative thinking on ways to increase the UAE’s water supply;
In 2016, it was reported by The Washington Post that government authorities were examining the possibility of constructing a mountain in order to induce rainfall. When humid air hits a mountain, the air is pushed to climb, and as it does so, it loses heat.
- After that, the air might get saturated with water vapor and change into precipitation in the form of rain;
- Another proposed mountain-building endeavor in the Netherlands may cost as much as $230 billion, according to the most recent estimates;
Building a pipeline from Pakistan and transporting icebergs from the Arctic are two of the other potential methods of bringing additional water to the United Arab Emirates (UAE).
What are the dangers of cloud seeding?
Is There a Connection Between Cloud Seeding and Negative Effects on Human Health and the Environment? – The use of silver iodide to seed clouds has not been shown to have any negative consequences on the surrounding environment, according to the findings of specialists.
The amount of silver that may be found in a storm as a result of cloud seeding is nowhere near the permissible limit of fifty micrograms per liter. The iodine content of iodized salt, also known as the salt that is used by people, is significantly higher than that of this particular type of rainfall.
Researchers have not discovered any big difficulties in the cloud seeding operations, even in experiments that have lasted for 30 to 40 years. There is no discernible difference in the flavor or odor of the rainfall that falls from clouds that have been seeded.
- The two are so similar that it would be impossible for you to tell them apart;
- If cloud seeding were to become widespread on a much bigger scale, a number of industry professionals fear that it might result in silver toxicity and environmental issues;
However, we do not have enough information to definitively say whether or not cloud seeding poses a risk. In a similar vein, many individuals are concerned that cloud seeding may upset the natural equilibrium of moisture on earth. They are concerned that this may have an impact on the rate of evaporation and the amount of precipitation.
How much does it cost to make it rain in Dubai?
A Brief Overview  – Since the 1940s, researchers have been exploring the potential of cloud seeding as a technological tool. In the late 1990s, the United Arab Emirates became one of the first Middle Eastern governments to implement a cloud-seeding program.
The UAE was one of the first countries in the world to use this method. In partnership with the World Meteorological Organization, the United Arab Emirates (UAE) established the UAE Prize for Excellence in Advancing the Science and Practice of Weather Modification in the year 2005.
(WMO). Cloud seeding was initially implemented as a project by meteorological officials in 2010 with the intention of producing artificial rain. The project, which began out in July 2010 and had a total cost of $11 million USD, was successful in its goal of bringing rain storms to the deserts of Dubai and Abu Dhabi.
Does Dubai get cold at night?
Seasonal climate The daytime temperature during the winter season is often about 25 degrees Celsius (77 degrees Fahrenheit). Nighttime temperatures along the shore vary from 12 degrees Celsius (54 degrees Fahrenheit) to 15 degrees Celsius (59 degrees Fahrenheit), whereas in the desert they are 5 degrees Celsius (41 degrees Fahrenheit), with the evenings being reasonably chilly throughout the year.
Which countries do cloud seeding?
The results of operational cloud seeding operations in various nations, including the United States of America, China, India, Israel, South Africa, and Thailand, record increases of between 10 and 30 percent in the amount of precipitation and cloud ‘lifetime.’ Alternately, numerous research indicated that seeding had just a small amount of effectiveness.
Why is cloud seeding done in UAE?
THE CREATION OF CLOUDS IN THE UAE – The United Arab Emirates (UAE) has a long history of cloud seeding. More than twenty years have passed since the program was first put into action. The United Nations estimates that by the year 2025, around 14% of the world’s population would be affected by water shortage.
It is anticipated that dry nations such as the UAE would experience a more severe water deficit. This is due to the fact that the region has an average yearly rainfall of around 120 millimeters, and occasionally even less than that.
The United Arab Emirates (UAE) cloud seeding effort is a component of the government’s endeavor to cope with the current as well as the future water demands of the country’s rising population. The United Arab Emirates Research Programme for Rain Enhancement Science, often known as UAEREP, got its start in the year 1990.
- Since that time, the mission of the program has remained unchanged: to develop a new supply of water for the nation by utilizing the most cutting-edge methods and technology currently available;
- The undertaking has been collaborated on by a number of organizations, one of which being the NASA;
Desalination facilities are the most practical option for the United Arab Emirates (UAE), although there are certainly other methods to guarantee access to usable water sources. However, when the expenses are compared, cloud seeding in the UAE is around sixty percent less expensive.
The seeding of clouds in Dubai and around the UAE has proven to be fairly successful. Around 200 rainmaking operations were carried out in 2019, with eight of the operations taking place in October 2019, leading to the collection of 6.7 million cubic meters of water.
Twenty-one additional seeding operations were carried out during the first half of the year 2021, bringing the total to 219. These figures indicate the relevance of artificial rain in the UAE as well as the advantages it provides.
How does cloud seeding work in Dubai?
How does it work? – A graphical representation to aid in the explanation of the cloud-seeding process that takes place in the UAE. Researchers in the United Arab Emirates are putting a novel approach to cloud seeding to the test by employing drones that emit electric zaps into the atmosphere. Researchers discovered that jolting droplets in the clouds can force them to cluster together.
[Citation needed] The bigger raindrops that are produced as a consequence then fall to the ground rather than melting in midair, which is often what happens to the smaller droplets in the United Arab Emirates because of the high temperatures and dense cloud cover.
Cumulus cloud formations are required for cloud seeding operations to be carried out, so as soon as they are spotted, the National Cloud Seeding Mission (NCSM) will quickly launch aircrafts carrying salt crystals, which are then mixed with magnesium, sodium chloride, and potassium chloride before being shot into the sky.
- The salt crystal flares promote the creation and release of cloud moisture, which eventually converts into precipitation;
- This process is repeated until precipitation occurs;
- According to information obtained by Gulf News, the NCM is equipped to carry out cloud seeding operations with six pilots and four aeroplanes;
The effort that aims to boost the amount of rain droplets that fall to the earth will be called cloud seeding. Following the detection of cumulus cloud forms, the NCM will promptly deploy aircrafts carrying salt crystals, which will then be fired into the sky together with magnesium, sodium chloride, and potassium chloride.
- It works by sending the aircraft to the cloud and targeting the updraft to seed it, which helps the small rain droplets to be bigger and heavier, so that it will fall to the ground, said Al Obeidli, who emphasized that no harmful chemicals were used in the process;
“It works by sending the aircraft to the cloud and targeting the updraft to seed it,” he said. “It helps the small rain droplets to be larger and heavier, so that it will fall to the ground The mission to seed clouds is not confined by the changing of the seasons; rather, it is carried out throughout the year whenever seedable clouds are spotted.
- Even if the initiative has the potential to increase the total quantity of rainfall, it cannot take sole credit for the precipitation because the overall success rate of cloud seeding ranges from 15 to 30 percent worldwide;
The World Meteorological Organization reports that as many as 56 nations are employing cloud seeding technology, mostly in an effort to alleviate drought conditions in countries such as China, Indonesia, and the United States. Shawky Mabrouk is a forecaster at the National Centre for Meteorology and Seismology’s cloud seeding branch.
Abdel-Krim Kallouche is responsible for the image that was taken from the Gulf News Archives. According to the World Wildlife Fund, recent estimates suggest that two-thirds of the world’s population may experience water shortages by the year 2025.
These shortages might be caused by climate change. In spite of the fact that governments from all over the world are continuing their study on the rain-making project, the United Arab Emirates continues to be in the forefront of paving the way for worldwide cloud seeding research.
Is there technology to make it rain?
In order to induce precipitation, scientists are zapping clouds with electricity. In an effort to induce precipitation through the use of drones, an electrical charge will be applied to the clouds. (CNN) The United Arab Emirates (UAE) is in desperate need of additional freshwater due to its severe desert environment and low annual rainfall average of about ten centimeters (four inches).
Which chemical is used in artificial rain?
This year’s monsoon was very fruitful, which brought joy to people all around the country. However, other regions, most notably those in the states of Karnataka, Andhra Pradesh, and Maharashtra, were not as fortunate as the others. The governments of these states came to the conclusion that they might alter their destinies with the use of a method of causing rain to fall artificially known as “cloud seeding.” Karnataka has already begun seeding the clouds that are over its sky (the effort did actually prove to be worthwhile), and other states are beginning to do the same thing.
But despite their best efforts, Andhra Pradesh and Tamil Nadu were not successful in their attempt to sow clouds in the past. Cloud seeding is a method that was developed in the late 1940s and is described as the purposeful modification of clouds to increase rainfall.
Certain compounds, such as sodium chloride (common salt) and silver iodide (another non-toxic chemical), have the ability to increase rainfall if they are sprayed from the air (with the assistance of airplanes and, on occasion, rockets). During the 1940s and 1950s, specialists at the General Electric Research Laboratory (gerl) in the United States brought the method to its current state of perfection.
- Irving Langmuir, a chemist who won the Nobel Prize in 1932, and Vincent J;
- Schaefer, who worked under him, are acknowledged for their groundbreaking contributions to this area of study;
- The method included There is a continuous circulation of millions of tons of water in the atmosphere, which may be found in the forms of vapour, droplets, and ice particles;
At times, clouds are composed of both water droplets and ice crystals, but more often than not, they are composed of water droplets alone. Due to the fact that the droplets are so minute, it takes at least a million of them to create a single raindrop. The formation of droplets surrounding small particles of dust, smoke, salt crystals, dirt, and other elements that are abundantly present in the atmosphere is the initial step in the process of cloud formation.
Clouds can be formed from a variety of substances. Scientists categorize these particles as cloud condensation nuclei. A couple of these particles are particularly noteworthy; they are referred to as ice-forming nuclei, and they are located on the surfaces of the water droplets that create ice (due to their capacity to absorb water).
In most cases, there is a limited supply of the unique nuclei (this may be a reason for the rainfall variations). The procedure in which the droplets get condensed is an extremely significant step. It happens when the temperature of the air lowers, which causes a reduction in the capacity of the air to contain water vapour.
As a result, it happens. If the air is allowed to continue to cool, it will eventually reach the point where it has reached its maximum capacity for the quantity of water that it can retain. The term “dew point” refers to this particular temperature.
At this stage, the water vapor starts to turn back into smaller and smaller droplets. The process of condensation can result in two different kinds of precipitation: “warm rain” and “cold rain.” The latter occurs in areas that are considered to be tropical; the process is given this name because precipitation falls from clouds in locations where the temperature is higher than 0 degrees Celsius.
When bigger water droplets hit with and absorb smaller water droplets, this results in the formation of rain in the “warm clouds.” For the purpose of producing ‘warm rain,’ substances such as table salt, which are capable of drawing moisture from the air, are typically utilized.
The phenomenon known as “cold rain” takes place when the temperature within all or some regions of a cloud is lower than 0 degrees Celsius. The majority of the time, these clouds are made up of ice crystals in addition to water droplets. The crystals expand at a quick rate, absorbing moisture from the water droplets that are located everywhere around them, until the weight of the crystals forces them to fall.
In the process of descending, the crystals might potentially melt and combine with smaller droplets of liquid water, after which they could potentially condense into raindrops in a way that is analogous to the phenomenon known as “warm rain.” In the event that the crystals do not melt, there is a possibility that they will agglomerate into huge snowflakes and fall to the earth as snow.
Silver iodide or dry ice (solid carbon dioxide) is utilized in order to provide naturally deficient clouds with the appropriate concentration of ice crystals in order to boost precipitation through the process known as “cold rain.” According to the findings of many scientific studies, the practice of weather manipulation might result in an average increase of 15-24 percent in precipitation.
However, the success rate might be as low as thirty percent due to the fact that scientists do not fully understand the science of cloud formation and the fact that not all clouds produce rain. In addition, there are occasions when circumstances that are necessary for precipitation to take place are not satisfied, which results in either very light precipitation or none at all.
The vertical and horizontal dimensions of the clouds, the lifetime of the clouds, the sizes and concentrations of cloud droplets and ice particles, and the lifetime of the clouds are the most important conditions for both the beginning of rainfall and the determination of how much rainfall will occur.
The process of seeding the cloud can even have a positive effect on one or more of these elements if the conditions are right. However, the whole cost might be seen to be exorbitantly high. Despite the fact that GERL had the intellectual property rights to the technology, the company decided to release it into the public domain because it feared that private companies would use it to artificially increase rainfall in areas that already received an abundant amount of precipitation.
Even while it isn’t harmful in any other way, the seeding might cause it to rain heavily in areas where it wasn’t supposed to, which could lead to flooding. However, China has been putting the method’s full potential to use in rain-deficient provinces, notably those that are located in the northern regions of the nation, in order to maximize its effectiveness.
How are artificial clouds made?
A man-made cloud was produced in an otherwise clear environment at a temperature below 0 degrees Celsius by dispersing pellets of dry ice into air that contained a higher concentration of water vapor than what would be expected to be present at the saturation point with regard to ice.
