The city in the clouds - Dubai

Dubai's skyscrapers poke through a carpet of fog at night in dramatic images taken from 800ft up in the air. The world's tallest building - the 2,700ft-high Burj Khalifa - can be seen bursting through the dense fog banks which descend on the city in March year year. In other pictures, the lights from Dubai's shops and apartments illuminate the fog from below at sunset.
