Hook echo

**Original** - A Doppler on wheels image of a tornadic thunderstorm near La Grange, Wyoming captured during the VORTEX2 project. In the velocity image on the left, Blues/green represent winds moving towards the radar, and reds/yellows indicate winds moving away from the radar. The reason that some of the darker blues contain red/yellow within them is a trait known as Aliasing, where the winds are moving faster than the radar can detect. In the reflectivity image on the right, the main body of the storm can be seen, with the appendage on the bottom of the storm being a hook echo, which is associated directly with the tornado, and the tornado circulation itself can be seen as the doughnut like shape in the later part of the animation.

Reason: High quality radar animation showing a severe storm, hook echo, and tornado vortex signature.

In the caption all the colors represent winds moving towards the radar? franklin 23:11, 29 January 2010 (UTC)[reply]
- Wow...I never caught that...thanks. Corrected it. Ks0stm ^(T•C•G) 04:07, 30 January 2010 (UTC)[reply]
Comment: I'm concerned about the size of the animation and the resources it hogs. When I try to scroll past the nomination it locks up my browser for half a minute or so, and I've had the same problem when viewing the Hook echo article. Actually viewing the image page itself is even worse. I'm not on a very fast connection, fair enough, but is anyone else having difficulty with it? From what I can tell, the right hand frame is communicating the most information, as it's the part that most clearly shows the hook echo. Couldn't this frame stand alone? Halving the animation would be good, I think, making it more easily understandable, more easily viewable, and hopefully not kill my browser, :-). Maedin\^talk 09:47, 3 February 2010 (UTC)[reply]
- That would be fine, but if that happens the halved one needs to get uploaded as a different file...this one just got featured over at Commons. I don't really have the skills to edit an animation in half, though...is this something the Graphics Lab could do? Ks0stm ^(T•C•G) 15:18, 3 February 2010 (UTC)[reply]
  - Errmmm, pass? :) Even if they aren't familiar with .ogv, I guess they may know others who are or they might be able to figure it out. Hopefully, anyway! Maedin\^talk 16:34, 3 February 2010 (UTC)[reply]
