Why is hail falling in the UAE in the middle of summer?

When the mercury rises in the UAE during the summer, the last things residents expect to see falling from the sky are hailstones – but they have appeared this week.

Social media users in Al Ain have posted videos of hailstones that appear to be sized somewhere between a pea and a golf ball.

The sudden flurry created an unlikely winter wonderland at the height of another sizzling summer in the UAE desert.

It came amid a spell of cloudy weather and rain that primarily affected Abu Dhabi and Al Ain.

Why are we seeing hail in the summer and why are updrafts important?

Crucial to the formation of hail are updrafts of air, which keep ice particles suspended in the atmosphere and allow them to grow into hailstones before they fall to Earth.

Surprisingly, the conditions that are ideal for hailstone formation are more likely to be seen in summer in the UAE.

“With warmer temperatures, the updrafts are stronger and sustained in time,” said Dr Diana Francis, an assistant professor and head of the Environmental and Geophysical Science (Engeos) Lab at Khalifa University in Abu Dhabi.

“That’s why the UAE witnesses hailstones when convective clouds occur during summer, when the temperatures are very high.

“The warm air naturally rises up, which fuels and maintains strong updrafts within the convective clouds.”

David Schultz, a professor of synoptic meteorology at the University of Manchester in the UK, said a number of factors, including a weather front or a sea breeze, could create an updraft capable of keeping ice particles in the atmosphere to form hail.

“What you need to start that updraft is usually a convergence of air coming from various locations. There are a number of ways that could happen,” he said.

The terrain could also cause an updraft, he said, with mountains able to cause the air movement required.

How do hailstones form and grow?

According to US space agency Nasa, the starting point for hailstones can be aggregated ice particles, known as graupel, or frozen raindrops.

The water exists in frozen form because temperatures 5km or 6km up in the atmosphere are below freezing, said Prof Schultz.

“Any cloud producing rain or snow at the surface of the middle or high latitudes … will start out as ice or snow,” he said.

“The conditions that form hail – you will have very strong updrafts into these clouds.”

“You can imagine that [hailstones] several centimetres across require even stronger [updrafts] in the atmosphere to keep [them] suspended in the air,” Prof Schultz said.

Dr Francis said that large hailstones were the result of several down-and-up movements of the hail that had initially formed within a cloud.

“They get tossed back up to the top of the storm by another updraft,” Dr Francis said. “Each trip above and below freezing adds another layer of ice until the hail becomes heavy enough to fall down to the surface.”

Nasa notes that each hailstone can experience both dry growth, when their surface remains dry, or wet growth, when a water-ice mesh forms. The combination creates a layered internal structure.

Why don't hailstones melt as they fall to Earth?

Eventually the hailstones become so large and heavy that the updrafts cannot keep them suspended any longer and they fall to Earth.

“Because they're falling quite rapidly, several metres per second, they can fall relatively quickly before they have time to melt,” Prof Schultz said.

He said hailstones could fall even in equatorial regions, as long as there was a strong enough updraft and they fell too fast to melt on the way down.

According to Nasa, hailstones are typically about 1cm in diameter, but some as large as 15cm in diameter have been recorded.

Conflict, drought, famine

Estimates of the number of deaths caused by the famine range from 400,000 to 1 million, according to a document prepared for the UK House of Lords in 2024.
It has been claimed that the policies of the Ethiopian government, which took control after deposing Emperor Haile Selassie in a military-led revolution in 1974, contributed to the scale of the famine.
Dr Miriam Bradley, senior lecturer in humanitarian studies at the University of Manchester, has argued that, by the early 1980s, “several government policies combined to cause, rather than prevent, a famine which lasted from 1983 to 1985. Mengistu’s government imposed Stalinist-model agricultural policies involving forced collectivisation and villagisation [relocation of communities into planned villages].
The West became aware of the catastrophe through a series of BBC News reports by journalist Michael Buerk in October 1984 describing a “biblical famine” and containing graphic images of thousands of people, including children, facing starvation.

Band Aid

Bob Geldof, singer with the Irish rock group The Boomtown Rats, formed Band Aid in response to the horrific images shown in the news broadcasts.
With Midge Ure of the band Ultravox, he wrote the hit charity single Do They Know it’s Christmas in December 1984, featuring a string of high-profile musicians.
Following the single’s success, the idea to stage a rock concert evolved.
Live Aid was a series of simultaneous concerts that took place at Wembley Stadium in London, John F Kennedy Stadium in Philadelphia, the US, and at various other venues across the world.
The combined event was broadcast to an estimated worldwide audience of 1.5 billion.

This year’s projects are in partnership with Street Child Nepal, Larchfield Kids, the Foundation for African Empowerment and SOS Children's Villages. Since 2001, the organisation has raised more than $3.5 million (Dh12.8m) in support of over 50 children’s charities.

Noor Dubai Foundation

Sheikh Mohammed bin Rashid Al Maktoum launched the Noor Dubai Foundation a decade ago with the aim of eliminating all forms of preventable blindness globally. You can donate Dh50 to support mobile eye camps by texting the word “Noor” to 4565 (Etisalat) or 4849 (du).

Tips to keep your car cool
  • Place a sun reflector in your windshield when not driving
  • Park in shaded or covered areas
  • Add tint to windows
  • Wrap your car to change the exterior colour
  • Pick light interiors - choose colours such as beige and cream for seats and dashboard furniture
  • Avoid leather interiors as these absorb more heat
Cultural fiesta

What: The Al Burda Festival
When: November 14 (from 10am)

The Al Burda Festival is a celebration of Islamic art and culture, featuring talks, performances and exhibitions. Organised by the Ministry of Culture and Knowledge Development, this one-day event opens with a session on the future of Islamic art. With this in mind, it is followed by a number of workshops and “masterclass” sessions in everything from calligraphy and typography to geometry and the origins of Islamic design. There will also be discussions on subjects including ‘Who is the Audience for Islamic Art?’ and ‘New Markets for Islamic Design.’ A live performance from Kuwaiti guitarist Yousif Yaseen should be one of the highlights of the day.

Is it worth it? We put cheesecake frap to the test.

The verdict from the nutritionists is damning. But does a cheesecake frappuccino taste good enough to merit the indulgence?

My advice is to only go there if you have unusually sweet tooth. I like my puddings, but this was a bit much even for me. The first hit is a winner, but it's downhill, slowly, from there. Each sip is a little less satisfying than the last, and maybe it was just all that sugar, but it isn't long before the rush is replaced by a creeping remorse. And half of the thing is still left.

The caramel version is far superior to the blueberry, too. If someone put a full caramel cheesecake through a liquidiser and scooped out the contents, it would probably taste something like this. Blueberry, on the other hand, has more of an artificial taste. It's like someone has tried to invent this drink in a lab, and while early results were promising, they're still in the testing phase. It isn't terrible, but something isn't quite right either.

So if you want an experience, go for a small, and opt for the caramel. But if you want a cheesecake, it's probably more satisfying, and not quite as unhealthy, to just order the real thing.
