You can definitely see, through the rolling motion of the updraft, the horizontal vorticity and thus helicity of the updraft itself. Notice how the far left portion of the updraft remains mostly "confined" or "straight" in that the bubbling updraft does not bulge out towards the left, but has a definite boundary and proceeds to rise to the right of the screen. This is indeed a super cell.
A wonderful timelapse! From someone who's been doing them 33 yrs. Just a great timelapse. Supercell? Rotation would be hard to see, but could be implied from the tilted, rolling updraft portion starting between the silos and over the long barn. That would be the 'rotation' part of the equation. A supercell need not have a back-sheared anvil. Given a high jet stream to storm motion, the top can just get sheared away. Again. Excellent timelapse. Steady frame, nice foreground, long duration!
this is awesome! and here in long island a tornado just recently touched down just south of me. We had about 55 kts of shear and about 1500 CAPE value with a southwest flow with dewpoints near 70!
Look at any other videos of a super cell and you will notice that there is one side of the meso that has a very defined edge, usually the west side of the updraft, that is nearly in contact with the RFD. This is a good indicator of a super cell.
@haloniels1997 That's what forms the typical anvil shape of a thunderstorm! It's raising air within the clouds. At a certain height though the cold air meets hotter air above it, so the cloud spreads, like the top of an anvil :)
Gotta love YT comments wanting to argue. I have a supercell time lapse video as well and there are plenty of comments saying that it's not a supercell. haha Good stuff. Anyway, this is a great time lapse man. Good job!
@retsuzchannel I dont live in Poland, but I know there are alot more than 3 supercells per year. I live in Slovenia (NOT Slovakia), and here we usualy get around 6-10 confirmed supercells per year. There are probably more that are not confirmed :)
I'm going to steal a line from ESPN's NFL Monday Night Countdown and use it on some of the comments directed to the uploader of the video. "C'MON MAN!" -- That is definitely an incredible developing supercell thunderstorm! The anvil and overshooting top are clearly visible. You can even see some pileus above the back sheared anvil, too. I would believe what the uploader states as being true. Why would you want to contradict the contents of a video from a storm chasing legend?
