What caused the storm that brought Dubai to a grinding halt?

A storm struck the United Arab Emirates and Oman today bringing record rains that flooded highways, flooded homes, gridlocked traffic and caught individuals in their homes.

A minimum of 20 individuals were reported to have passed away in the deluge in Oman while another individual was said to have actually passed away in floods in the UAE that closed government workplaces and schools for days.

The storm had actually initially struck Oman on Sunday before it pounded the UAE on Tuesday, knocking out power and triggering substantial disturbances to flights as runways were developed into rivers.

In the UAE, a record 254 millimetres (10 inches) of rainfall was tape-recorded in Al Ain, a city surrounding Oman. It was the biggest ever in a 24-hour duration since records began in 1949.

DID CLOUD SEEDING TRIGGER THE STORM?

Rain is rare in the UAE and somewhere else on the Arabian Peninsula, that is generally understood for its dry desert climate. Summer season air temperature levels can overlook 50 degrees Celsius.

However the UAE and Oman also do not have drainage systems to deal with heavy rains and submerged roads are not unusual throughout rainfall.

Following Tuesday's events, questions were raised whether cloud seeding, a procedure that the UAE often conducts, might have actually caused the heavy rains.

Cloud seeding is a procedure in which chemicals are implanted into clouds to increase rains in an environment where water scarcity is a concern.

The UAE, situated in one of the hottest and driest areas on earth, has been leading the effort to seed clouds and increase precipitation.

But the UAE's meteorology agency told there were no such operations before the storm.

WHAT ABOUT ENVIRONMENT CHANGE?

The substantial rainfall was rather most likely due to a regular weather system that was worsened by environment change, professionals say.

A low pressure system in the upper environment, paired with low pressure at the surface had imitated a pressure 'squeeze'. on the air, according to Esraa Alnaqbi, a senior forecaster at. the UAE federal government's National Centre of Meteorology.

That capture, intensified by the contrast between warmer. temperature levels at ground level and colder temperatures higher up,. produced the conditions for the powerful thunderstorm, she stated.

The unusual phenomenon was not unexpected in April as. when the season alters the pressure modifications quickly, she said,. adding that climate modification also likely added to the storm.

Climate scientists say that increasing international temperature levels,. brought on by human-led climate change, is resulting in more severe. weather occasions around the world, consisting of intense rains.

Rainfall from thunderstorms, like the ones seen in UAE in. recent days, sees a specific strong boost with warming. This is due to the fact that convection, which is the strong updraft in. thunderstorms, strengthens in a warmer world, stated Dim Coumou,. a professor in environment extremes at Vrije Universiteit Amsterdam.

CAN'T PRODUCE CLOUDS FROM ABSOLUTELY NOTHING

Friederike Otto, a senior speaker in environment science at. Imperial College London, said rains was ending up being much heavier. around the world as the climate warms due to the fact that a warmer. environment can hold more wetness. It was misleading to talk. about cloud seeding as the reason for the heavy rains, she. said.

Cloud seeding can't produce clouds from nothing. It. encourages water that is currently in the sky to condense faster. and drop water in certain locations. So first, you need moisture. Without it, there 'd be no clouds, she said.

Global warming has resulted in extraordinarily warm water. in the seas around Dubai, where there is also very warm air. above, stated Mark Howden, Director at the Australian National. University's Institute for Environment, Energy & & Catastrophe Solutions.

This increases both prospective evaporation rates and the. capability of the environment to hold that water, allowing larger. dumps of rains such as what we have actually just seen in Dubai.

Gabi Hegerl, a climatologist at Edinburgh University, stated. that extreme rains, like in the UAE and Oman, was likely to. get worse in many locations due to the effects of environment change.

When conditions are best for really heavy rain, there's. more wetness in the air, so it rains harder. This extra. moisture is because the air is warmer, which is due to the fact that of. human-caused environment change, she said.
