![]()
Was a good day for October!
Long lived cold core that I intercepted North of London took me quite a distance away from town. I had to head ENE to keep up. The chase began with an interesting event, an updraft formed fast ahead of the main line. it looked like something from a warm front not a cold core. This shot is me looking up its north side. ![]() As I approach a sinking motion becomes apparent on the backside, I'm driving south because I overshot how far north I wanted to go. durr ![]() Here a small area of rotation persisted for a few minutes before falling apart. It had some decent speed to it, no funnel though. ![]() The updraft began to fall apart after that, also the gust front was catching up behind me now from the west ![]() Now under the original updraft, this was my view looking straight up. Some rotation still was going on slowly. ![]() This had some kind of horizontal tube in it, but fell apart fast. ![]() This feature was rotating, had a circular shape inflow tail and lasted around half an hour changing shape, so I want to call it a wall cloud. I still think it was odd though forming from a cold core right next to a weak gust front... Here it is early on ![]() About 20 minutes later it had become this! With good rotation and inflow tail still, the side on the right of the image had the most intense motions. ![]() Here it was about ten minutes later, a lot weaker than before but still spinning a bit ![]() Southern edge of the core had a neat feature on it now and LOTS of cg's ![]() another 15 minutes or so later the dying wall cloud made one final appearance change, I had caught up to it finally! ![]() After that it finally fell apart for good, I then decided to head north into the core then west and see what was up with the north side..... I saw a nasty looking line with a pocket of intense vertical motions; I followed for awhile until it too fell apart. Here is the view coming out of the core ![]() getting closer, strongest up motion was the area right above the road ![]() Last shot I take on the way back as the system weakens ![]() This little guy was in London and had some rotation! Nice surprise on the way home ![]() This even smaller one had a small anvil downstream and some rain and an inflow tail! ![]() [media]http://www.youtube.com/watch?v=maLDm-L6Fxs[/media] Last edited by Itchy; 08-13-2010 at 02:00 AM. |
