The worst rainstorm in the United Arab Emirates in 75 years: Dubai Airport is paralyzed Is the heavy rain in the desert caused by artificial rain?
On April 16, the United Arab Emirates experienced the heaviest rainstorm in 75 years, including Dubai International Airport and many flooded roads; the rain in Dubai exceeded 142 millimeters on the 16th, far higher than the annual rainfall in previous years, hundreds of flights at Dubai Airport were grounded, and airport services were still unable to normal operations resumed from the 17th, heavy rains caused major flooding. However, in the opinion of the public online, there was an argument that the heavy rains were the result of the artificial increase of water regularly organized by the United Arab Emirates National Meteorological Center of the United Arab Emirates, which the responsible for monitoring the increase of artificial water, first. The deputy director later made the rumors official, saying that no artificial water raising work had been carried out before or during this period of heavy rain, and it was identified by the use of artificial water raising to generate or change major weather. real events are not based on current technology.
Since the United Arab Emirates began recording weather data in 1949, it has never received such heavy rainfall as this one. day. in one day.
More than 250 millimeters of rain was recorded in some areas of the United Arab Emirates, with Al Ain, the city with the worst rainfall, recording 256 millimeters of rain.
Because the Arabian Peninsula has been dry for many years and it rains very often, many cities lack drainage systems. Building facades were damaged. Since the 17th, heavy rains After the closure, Dubai Airport was still unable to resume normal operations due to water accumulation, road blockage and other effects.
Rainfall in Dubai exceeded 142 millimeters on the 16th, well above the 97 millimeters of rain in previous years Hundreds of flights to Dubai Airport… Due to the prolonged drought Peninsula Arab, rainfall is unusual and many cities are sparse. Unprecedented heavy rain caused…
The number of passengers at Dubai International Airport in 2023 will be 87 million, and 5 airlines will use Dubai Airport as a hub compared to the population of the UAE of about 10 million, the number of passengers at Dubai Airport and all the airports in the UAE as a whole. 1.34 The number of passengers per billion is impressive, and it also shows the important role that the UAE plays in the global aviation industry.
According to Flight Aware data, around 290 flights to and from Dubai International Airport were canceled on the 17th, and another 440 flights were delayed.
Emirates, the largest airline in the Middle East, has announced that it will suspend check-in procedures for passengers departing from Dubai from 8am on the 17th to midnight on the 18th from Dubai Airport Airlines also reported flight delays, with low-cost airline Flydubai canceling all flights by 10am local time on the 17th.
Dubai Airport also advised on the morning of the 17th that “do not go to the airport unless necessary” and indicated that flights were delayed or diverted to other airports.
The United Arab Emirates government also issued a warning ahead of the heavy rains, asking people to stay at home unless going out is “absolutely necessary” and ordering that most public sector employees working remotely. Schools across the country were closed, delivery services stopped, subways were flooded, and the few people who had to go out were walking through the water.
The UAE authorities have not yet provided complete information on the total damage or casualties caused by heavy rains However, in Ras al-Khaimah, the northernmost part of the UAE, police reported that a 70- year to be swept away by floods. when his vehicle was swept away.
In addition to the United Arab Emirates, rain also occurred in Oman, Bahrain, Qatar and Saudi Arabia on the 16th that heavy rains caused major floods, killing at least 18 people, including 10 school children were swept away in a car by an adult; later the search and rescue team found the body of a girl in Saham district in the north-east of Oman Currently, the number of people known to have died in heavy rain in Oman.

▌ The heavy rain is caused by artificial water?
The heavy rains caused disasters and led to doubts from the outside world It was believed that the UAE authorities may have usedSeeding clouds, only when technology gets out of control can disaster happen. But the National Center of Meteorology (NCM) of the United Arab Emirates immediately rejected these rumours. Omar Al Yazeedi, the deputy director of NCM, also said: “We did not do any work to increase the water before and after this storm. There is no need to increase the water.”
However, Forbesreport, the UAE authorities have given conflicting statements. NCM meteorologist Ahmed Habib once revealed that they sent out drones to increase rain on the 15th and 16th later NCM deniedthis statement and said that the authorities increased rain on the 14th and 15th, instead of the 16th when the wind and rain increased. But later, after the deputy director repeated the above statement, the various explanations only added to the doubts of the outside world.
Artificial water, also known as artificial water, is often thought of as being able to “spawn water out of thin air”. components or salt particles in the air By increasing the surface area on which the concentration of water occurs could accelerate the collision of water molecules, thus increasing the chance of precipitation in a certain place.
Therefore, completely dry areas cannot yet use water augmentation technology, but must wait for the weather with sufficient moisture. Maarten Ambaum, a professor at the Department of Atmosphere at the University of Reading in the UK, pointed out that the target clouds for artificial rain enhancement are often not susceptible to rain and are unlikely to produce severe storms.
It has been more than 70 years since artificial precipitation was invented in the 1940s. It is usually released from the surface or using devices such as aircraft and drones.
In the center and south of the Arabian Peninsula, where the United Arab Emirates is located, there is a subtropical desert climate, with an annual rainfall that does not exceed 200 millimeters. growth, there has been a shortage of fresh water resources for years. The United Arab Emirates not only has the world’s largest desalination plant, but also began using natural materials such as salt grains to artificially increase precipitation as early as the 1990s, said United Arab Emirates media “The National”.reportAl Ain, the city with the heaviest rain this time, is one of the main bases for artificial water augmentation.
However, the impact of artificial rain on climate change is currently controversial. First, current technology cannot control the details of irrigation, such as the amount, location and timing of the rain, very accurately. In addition, because chemical raw materials are used to increase water in some areas, if they are used too often, what will be the effect of climate change and on the environment in general Not enough is known yet.“BBC” was reported once, the United Arab Emirates made at least 185 artificial water increases in 2019, and heavy rains and floods also occurred at the end of that year. It is still difficult to clarify to what extent the flood is related to artificial rain, or if it is just one of the real weather disasters caused by climate change.
Esraa Alnaqbi, another senior researcher at NCM, said that two tropical low pressures are affecting the UAE this time, together with high temperature pressure on the ground and cold air at high altitude, strong storms will come.
Climatologists also believe that the global warming crisis is causing the global temperature to rise and is therefore more likely to exacerbate this phenomenon. Dim Coumou, professor of meteorology at Vrije Universiteit Amsterdam, said: “Under the warming phenomenon, the rain that causes thunderstorms will be particularly heavy, because the high-temperature environment will make the updrafts created by thunderstorms stronger. ” —— For every 1 degree Celsius rise in temperature, the humidity in the air will increase by 7%, and the intensity of the rain will also increase.
