Wave Soaring
This is a lenticular cloud caused by South Westerly winds over the Great Dividing Range. These winds cause lift to be generated as "waves" and allow gliders to climb to heights over 20000ft. Pilots wear oxygen masks and thick socks for these flights. The winds reach speeds over 140 kph at these heights but it can be dead calm on the ground. Boonah "wave" happens in winter usually July till September. This photo was taken on 8/6/10 and there have been several good wave flights already this year to 10000ft
