Several peculiarly shaped clouds formed over the city of Antwerp, Belgium, in the afternoon of June 16, 2006. This one was captured at 4:54 p.m. A strong northwestern breeze and an important temperature inversion at 1,500 m (4.900 feet) were instrumental in creating these bizarre shapes.
Camera : Olympus C200Z. Time exposure : 1/1000 sec. Focal number : 5.6. Focal length : 36 mm. ISO : 100.
