“As the air rises in the tropics, it starts being transported away from the tropics at higher latitudes,” says Prof David Schultz, professor of synoptic meteorology at the University of Manchester in the UK.
At subtropical latitudes, the air tends to descend, warming and meaning that, as Prof Schultz describes, it “is not favourable for the creation of deep, fluffy clouds”.
So heavy cloud cover in the UAE is rare.
“Many of the other deserts are in the subtropical latitudes, like Australia, the deserts of China, the deserts of North America. They’re devoid of lots of cloud because the air is descending,” says Prof Schultz.
“There’s not going to be a lot of moisture from the south,” says Prof Schultz.
“There will be some, but not as dramatic as the air being flowed into India.”
