    I do like a good lenticle. Is that coming or going?

    Today’s East of Jindy, more a cousin to lenticular, thermal or cumulos wave clouds. The upper wind treating the cloud like a mountain range and forming a wave over the top with the tell tale lenticular cap cloud form to mark it.

    Re the OP. We used to hunt them down to get good wave soaring conditions over the Snowy Mountains, ex Polo Flat airfield in Cooma North. One of our crew hit nearly 29,000 feet over the Main Range using one of the wave systems that the lenticular cloud symbolises the peak of. :D

    Gees that is pretty good. Best I heard about was the wave over cenrtal NSW caused by cyclone Tracy all those years ago. Lots of international pilots a bit gobsmacked by what they experienced.

    Only diamond my mother did not get was the height one, and only because we did not have oxygen.

    Just a little lenticular happening here. Was more apparent just a little earlier when it was a bit darker.

    Mt Yote, near Niseko village.

    My first thought when looking at those was 'why TF would a pilot be wanting to fly anywhere near that shit?' then I read the bit about you being a glider...
    Thanks for sharing. When were they taken?

    Hi Pow,
    yeah, sometimes at 20,000ft in -20c I ask myself the same, but keep going back for more (bit like skiing). And the turbulence near the ground can be frightening. I fly from the Bunyan airfield just north of Cooma, the wave can extend from Jindabyne all the way up past Canberra, these were taken around Bredbo and Berridale.

    We had ground breaking electric booties and mittens. Early 80s.

    Many thermals and oxygen. We flew from the old club field at Cooma North Polo Flat.

    Yes - lee of NZ's main divide is prime for lenticular formation. Seen some beauties over the years.

    Not lenticular but I thought I would put this here. Taken from the Hernes Oak overpass between Moe and Morwell this morning.

    A good reason why we saw light rainfall ahead of the frontal band this morning. Mid-level overshooting at play.

    ^ Oh and Port Augusta mid winter pre frontal is amazing for lenticular and Kelvin-Helmholtz wave formations.

    I reckon I've some photos somewhere. Will try to dig them out.

    Wow, those War of the Worlds clouds in the last few posts are fantastic. I love seeing interesting cloud formations. @di6loc I’d love to see those Kelvin Helmholtz photos if you find them. What I wouldn’t give to see those in person and from a plane!

    These photos are from Mt Buller a couple of weeks ago. A couple during the day that looked like flying saucers.

    The rest during sunrise.Mist rolled down the summit to the right, separated and formed individual lenticulars over Mt Little Buller in the pink dawn. They appeared to be living creatures, or spirits soaring and swooping across the sky, rising and falling over the contours of the hills. The rapid rate of swirling and twisting and colour changes as the early morning sun tinged tendrils as they swirled, was mesmerizing.

    Apologies for the flooding the thread with so many pictures but I just kept snapping as the clouds were constantly changing. Then it's difficult deciding which to cull!

    Without some wild manipulation Lenticular clouds never photograph as well as they appear thanks to their discus (2D) shape.

    If you look heaps carefully you might make out the wisp of thermal wave cloud over this snall cu. Alas it blued out & did not form a lenticular.
