Dubai flooding amid atypical heavy rains snarls traffic on UAE roads and airport runways​


Heavy rains lashed the United Arab Emirates on Tuesday, flooding portions of major highways, leaving vehicles abandoned on roadways across Dubai and grinding traffic at the city-state's huge international airport briefly to a complete halt. Meanwhile, the death toll from separate heavy flooding in neighboring Oman rose to 18, with others still missing as the sultanate prepared for the storm.

The rains began overnight, leaving massive ponds on normally parched streets and airport tarmacs as whipping winds contributed to flight disruptions at Dubai International Airport, the world's busiest for international travel and the home of the long-haul carrier Emirates. The airport said in a series of social media posts that all operations were halted for about 25 minutes on Tuesday afternoon, and that all arrivals would be diverted after that "until the weather conditions improve."

United Arab Emirates is using cloud seeding tech to make it rain​

  • In the 1990s, the UAE introduced a rain enhancement methodology called cloud seeding.
  • Cloud seeding is the process of increasing the amount of rain produced from the clouds above, which is designed to improve water shortage issues in arid regions around the emirate.
  • By the early 2000s, Sheikh Mansour Bin Zayed Al Nahyan, the vice president of the UAE, allocated up to $20 million for research into cloud seeding.
  • The UAE partnered with the National Center for Atmospheric Research in Colorado and NASA to set up the methodology for the cloud seeding program.
Skeptics have long argued that governments who have introduced weather modification techniques to their skies are "playing God."

During a visit to the NCM, General Director Abdulla Al Mandous told CNBC that the technology is "based on scientific background."

Al Mandous added that Abu Dhabi's program does not use silver iodide, a common crystal-like material used as a seeding agent in other countries. This material has been widely criticized for potential harmful effects on the environment and the public, however, some cloud seeding studies show there has been no substantial evidence to prove that at current levels it poses any toxic effects.

The NCM said it does not use any harmful chemicals in its operations. "Our specialized aircrafts only use natural salts, and no harmful chemicals," the organization told CNBC.

La pluie tombée représente près de deux ans de précipitations pour Dubaï.
En moyenne, la région reçoit environ 70 mm de pluie annuellement.

The city of Dubai was the scene of deadly floods caused by torrential rains.
Nearly 160 mm of rain fell in Dubai in less than 24 hours. This episode was so intense that the Middle Eastern city was submerged. The exceptional storm flooded the streets of the city, but also the tarmac of the international airport, the second busiest in the world. The establishment predicted that this bad weather would continue the next day. Several flights have been temporarily suspended.

According to the Royal Oman Police, at least 75 residents have been rescued in the last 24 hours.
The rain that fell represents almost two years of precipitation for Dubai.
On average, the region receives around 70 mm of rain annually.

 
Extreme rains have been known to fall since Thursday 18 April, causing many points in the province to be flooded. By Monday, about 110,000 people had been evacuated across the province, while 25,800 people were in emergency shelters, according to Xinhua.

Kenya's first-ever cyclone "could hit at any time."​


Kenyan President William Ruto warned that the situation due to devastating floods caused by torrential rains that have left at least 210 people dead will worsen, as the African country's first-ever cyclone "could hit at any time along the coast."

"Unfortunately, we have not seen the last of this dangerous period, as the situation is expected to worsen," he said. The Department of Ecology and the Climate Prediction Application Center (ICPAC) have issued a stark warning that Kenya could face its first ever cyclone," Ruto said in an address to the nation from the presidential headquarters.

The Council of Ministers was warned by experts on Thursday that Cyclone Hidaya could hit Kenya's coastal region in the coming days, according to local media.

Some really bad storms with tornadoes have been going across the US of late. This article about one in late April caught my eye.

Oklahoma storm had 3 extraordinary features, including a "wrong-way" tornado

Meteorologists stared at their radar screens in awe as a supercell thunderstorm performed several neat tricks.

By Jesse Ferrell, AccuWeather meteorologist and senior weather editor

Hours after a tornado was documented in Tillman County, Oklahoma, on April 30, meteorologists and weather enthusiasts were enthralled by a severe thunderstorm in the same county because several rare meteorological phenomena, including double tornadoes, a tornado track that looped back on itself and an "anti-cyclonic" tornado, were documented. Because the storm occurred after dark, photos and videos are few and far between, but it left its evidence on the radar.

Twin tornadoes

The radar shows the Tillman storm appeared to have two tornadoes at the same time. Having two tornadoes in the same storm, especially as one is dying and another is forming, is not rare, as supercell thunderstorms cycle their energy; in fact, two concurrent tornadoes in one storm have been documented via video on occasion, such as the twin tornadoes at Pilger, Nebraska, of June 16, 2014.

The first tornado from the Tillman storm also appeared to have looped over on its own track, which is rare but not unheard of.

Wrong-way tornado

The second tornado spawned by the Tillman storm spun the wrong way, exhibiting clockwise or "anti-cyclonic" movement. This is because the Coriolis Effect, which dictates rotation at the size of a tornado, is never 100 percent effective. It is estimated that only 1 to 2 percent of tornadoes rotate clockwise.

The radar showed winds toward the radar on the south side of the storm, with winds away from the radar on the north side, meaning that the tornado was spinning clockwise. The two tornadoes from the Tillman storm may have even experienced the Fujiwhara effect, spinning around each other.

A towering, rotating storm

The Tillman thunderstorm also appeared to have a complete cyclonic structure as high as 18,000 feet, which is rarely seen in radar data. Typically, tornadoes twist below the storm's base, which is also rotating but far beneath the top of the storm.

Tornadoes are rated on the Fujita scale based on a post-storm estimate of damage, and tornadoes in rural areas can be underestimated because there are no structures to indicate damage. Very little damage was done by these rural storms. The NWS said "this [first] tornado produced EF1 damage, although it was likely much stronger." The second anti-cyclonic tornado was also rated EF1.

Sudden floods around the Iranian city of Mashhad have taken the lives of at least seven people, with three more missing.
The head of the Khorasan Razavi Province Reza Abbasisaid at least seven people have died in the floods and three more are missing in the flash floods hitting the provincial capital and its neighborhoods. Many people were injured.
Heavy downpours hit the province, mainly the capital Mashhad and clogged the streets. Many vehicles also got stuck in the floods.
Abbasi said Red Crescent Society rescue teams and military forces have been dispatched to the affected areas. Enqelab Square in Mashhad is the hardest hit area and it will take more time to return back to normal.
Other cities in the province, including Fariman and Torghabeh, were also flooded.
Areas close to the northern border with Turkmenistan have seen heavy rainfall and large hail with streets, homes and shops all under more than 90cm of water in some locations. At the same time, further rain is expected across central Asia, with more predicted close to the Afghan and Tajik border.
City fire brigade divers retrieved the bodies of a man and a woman, both approximately 50 years old, in the northern Iranian city, which has seen several recent days of floods and freak weather events in part due to the wetter regional climate this year.
Rescue operations have continued late in the evening to find other potential victims.
