Original – A Doppler on wheels image of a tornadic thunderstorm near La Grange, Wyoming (USA) 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: This is a high resolution Doppler on Wheels radar animation of a tornado producing severe thunderstorm. It is by far Wikipedia's best and most educational depiction of a hook echo, thus adding significant EV to the article.

Comment: I don't know anything about the subject - is the left half of the image useful in understanding the hook echo? Other than that it looks good (I didn't read where you said "animation" at first though!) and I could well believe we don't have better given the provenance and technical difficulty, etc. Grandiose (me, talk, contribs) 17:16, 22 September 2012 (UTC)[reply]
- Yes, the left half does help to understand, at least in my view. In the velocity image where the winds blowing towards the radar are right next to the winds blowing away it indicates rotation...it's somewhat complicated to explain, but basically is like explained at Tornado vortex signature#Display.

Oppose Too knotty and mixed up view. Alborzagros (talk) 13:41, 23 September 2012 (UTC)[reply]
- Can you please explain "knotty and mixed up view"? Ks0stm ^{(T•C•G•E)} 22:03, 27 September 2012 (UTC)[reply]
Comment: Is the thumbnail supposed to move? It's sitting awfully still for me and the full resolution takes forever to load. --Paul_012 (talk) 13:41, 24 September 2012 (UTC)[reply]
- So far as I know the thumbnail does not move since the file is so large; you have to load the full resolution. Ks0stm ^{(T•C•G•E)} 22:02, 27 September 2012 (UTC)[reply]
  - Be better if it was converted into a movie so that it would play in-line of the page... Added. — raeky t 22:55, 28 September 2012 (UTC)[reply]
