Here's a few images of the monster cell which appeared over Maghera on friday evening August 1st. It had a very large mesocyclone and based on the visual features I believe this is a good candidate for a rare LP supercell over N. Ireland. It has been a major goal of mine to catch a Meso. So with a solar eclipse, the excitement of John's funnel and the meso during the evening, I would say that this would be a day which I will never forget. I have a report with images on my site...

Here's a video clip...

















A meso is a persistent rotating updraught within a storm cell. This one had an area of rotation longer than several football pitches end on end and was cranking for over 1.5 hours. It also produced inflow bands and a wall cloud. These cells are capable of strong tornadoes and big hail. They are rare in the UK but are a big attaction in the states.  More info...

Thanks very much guys!

Paul, I actually haven't. I wasn't going to because I thought I would be pushing my luck. Do you think I should?, and if so, which images should I send in?

Thanks  Smiley

Here's an annotated version with the storm structures identified. I forgot to mark the striations in the updraught near the word Mesocyclone which is another visual sign of rapid rotation.

Now that's a fabulous annotated photo Martin  - very informative for those of us who are some way behind you on the weather front Smiley

I'd seriously send in an unannotated version of that  pic to the Beeb - I don't think there's a restriction on how many times you can be on!

Glad you liked the annotated version. It took me some time to put that together.

I sent in the full size version of the above image and an annotated version and talked a bit about the phenomena. It's in their hands now. Hopefully it should generate some interest.

Thanks.

Martin, what a great photos!!  Smiley It looks like a real storm, not like other gentle storms. I have no words to comment, just beatiful weather. Underlined weather because when it is warm and clear (like today in Poltava) I can say there is no weather.
Especially liked your annotated photo  Smiley

Now I recall January. That's what I call weather!
