Dubai Introduction Part 3

Dubai's extravagance is a magnet for the rich and famous. And this is the place where the wealthiest of them come to stay.

The Burj Al Arab, one of the tallest and most expensive hotels in the world.

Week in the seven star palace could set you back $100,000 VIP arrive 700 feet up on the hill. A bad landing here isn't always a breeze.

Today, wind speed peaks at 45 miles an hour, a challenge even for former Canadian Forces pilot, Don Douglas were half a mile back 300 feet above the neck. And publishing on the final permit went to an hour for a little bit of turbulence.

There's one coming on one side of the stress and the other side and it kind of merged together and it caused a bit of turbulence closer and slower today was hearing but it can get worse.

The wind in Dubai can hit 80 miles an hour.

Protecting buildings from these storms is another challenge for the city's engineers.

And this is the place where they come to test their designs. Tom Bell right runs an outdoor laboratory that can simulate a desert storm and you got this thing set up correctly for these guys over here.

Tom's job is to test the cladding that makes up the skin of skyscrapers and he uses an old aircraft engine is a giant when machine.

This test today will test for everything that mother nature can start with the building. If the system is going to fail, we're going to find out where files the crew add water into the mix. So even tiny cracks in the panels show up. If the inspectors spot just a trace of water inside the design will fail.

So the guys all good, I'm told that's so that's that test out of the way. This this dynamic test is a great test the representative of the real winner of the weekend. It's the kind of forces that buildings have prevailed to resist.

But it's not enough just to protect the outer parts of a building.

In the Burj Al Arab the most impressive technology lies hidden under its skin.

The winds blowing across the Gulf are so strong they could bend or even break the buildings concrete core. So engineers wrap the Burj Al Arab in a strong steel frame bolted to a steel spy

an exoskeleton.

This ingenious invention spreads the force of the wind and stabilizes the concrete core inside the skeleton or shock absorbers. These moves against the direction of the wind and reduce the motion even more so guests can sip. They're expensive cocktails without feeling seasick.

But when the winds blow from the desert, there's another thread sand,

powerful sandstorms can appear totally out of the blue the race towards Dubai. At ferocious speeds, tilting thousands of tons of sand across the streets the most violent sandstorms can shut down the city for days

This one caught on tape reduces visibility to just a few feet sandstorms wreak havoc on anything that's not tied down the club gutters stop traffic and ground plane.

Dubai is in the firing line because it sits on the edge of the largest continuous stretch of sand in the world the rebel Cali desert it's not the place you want to be on a stormy day, it is very tedious Chelsea nothing and driving around in the genes if anybody had to save Catherine has venture deep into the rebel Cali otter mapping mission she's become a master in the science of doing driving desire to be really very high chance of getting stuck driving fast and furious to the key now and it's just a question of letting the car.

Today point in touching the braids because if you do that you just end up weighing in trouble very good reading the contours of these dudes helps Catherine power across them, he's gonna have to accelerate a bit of change it up is bit of self service,and it gives her clues about how the wind interacts with them through a bit like puzzles really is quite a lot of information in them this June, I can see that the shadow side is where the the winds coming from Clemson guys at the shadow side and then they're blowing off down the steep side quite briefly today, but most of the sand is still just rolling on the surface of the dunes here.

As the wind gets stronger, it starts to pick up heavier grains of sand.

When they crash. back down. They released a myriad of dust particles these below high affinity air in dense clouds of driving sand when they finally hit Dubai. They're not a welcome sight.
