The undulation of this spectacular cloud sitting above the Dunstan Range near Cromwell has been enhanced by speeding it up.

“When the nor’ westerly wind blows through Central Otago we often see excellent displays of lenticular cloud” says Steve Thomson of www.wowstockfootage.com .

“This was a very unique formation that sat above the Dunstan range for about 3 hours as if it was a huge wing gliding on the wind”.
