@Ondřej-Šutera this is what is requested:
https://www.weather.gov/jetstream/vel
It shows corrected Doppler velocities, so that it is possible to locate rotating wind areas on a small scale.
Right now, we all have to watch these when there are tornadoes in the US. It would be great to not only have this info layer, but if you went just a step further with some ML, you could autodetect likely areas where a tornado is either on the ground, or likely to form.
This would be amazing! It may also save lives, if done right. If you made a beta version, I think a number of us would use it. (I keep looking for it in the app, which is why I'm here 😃)
There's a whole community based around this concept in the US called storm chasers, or tornado hunters...
Cheers, and thanks!
