Hi Aussie Girl

I had to make a cheap little youtube so I could show you the video of the doppler. I used to be able to upload the link to the archive that you create with the Chasers and you could play around with the speed, go forward or rewind etc.

So hopefully this works and can explain a little. The 1st two images highlighted with a black circle, show the two interesting signatures showing rotation, they are both going clockwise in this storm as that was from the prevailing feeding winds or shear. Seeing rotation does not mean automatically there is a tornado. Usually there are other tell tale signs of a possible tornado such as a hook etc. and a more pronounced tightly wound rotation. And they can spin both ways. The corolla effect doesn’t play a big roll in storm cells unlike a cyclone. Storms are controlled more from where the main winds in the atmosphere are moving. But that is another big conversation and very interesting.

Another feature you can look at is the Towards and Away from the radar winds. When you see the Away wind mixed within the Toward winds or the other way around as well, it is also a bit of a tell tale sign that there could be rotation. It is not always the case as you could have a strong change coming through on a weak storm.





And hopefully the link works and you can see these two areas rotate clockwise as they approach the East.

You can see a larger rotation of the storm as it headed over the Bay/Sea. The rotation was very weak and indicated some fairly strong wind gusts. It is not the best one to actually see what rotation looks like.
