Hole Punch Clouds
« on: 01 June 2007, 08:26:41 AM »
MB, I was scanning through the photo gallery of yours and noticed a great photo of high level cloud with what seems to be a circular hole created by something (!).  I have no idea what it is, so could you explain some details of what you photographed?  Looks truly amazing!

Is it this sequence?

If so they are known as punch hole clouds. The holes develop as ice crystals above the main cloud layer fall through the clouds.

I've never heard of them and never seen anything like it. Why does it look like a funnel?  Is there some particular atmospheric condition above the cloud that makes it do this - more information please!

It's just something that has caught my attention greatly.

This is the best info I have found so far.

Doesn't sound like it is well understood. Feel free to post any info you find.

Another example I took on 10th March 2006

Checked the link to NOAA.  Well, well that was very interesting.  It really does look like something fell through the cloud blanket and left a gaping hole in it.

Thanks for that.  I might source some stuff out on it for interests sake.
