G'day All,

these are an interesting couple of shots. I have seen lots of pictures of
the 'shock wave'(for want of a better description) when serious vertical
development occurs in in towering Cu type clouds. But this is the first time
I have seen the 'shock wave' effect in a horizontal situation. The layer of
cloud was very thin - maybe 500/1000' thick at the most & they were moving
very quickly, so much so that just 20 mins after I took these pics it was at
7 ocktas of this very thin strato cu, as it had now become.

Anyhow I hope you enjoy these 2.

see ya
