I slightly understand the hook and the old Doppler showing a purple or dark color representing debris, but I’m sure that’s only if the debris field is that high up and a large amount. When looking at radar now with representations of tornadoes, I find it hard to pick out which part of the radar shows it. I’m sure this won’t be a popular question but anyone with knowledge of radar, your expertise would be appreciated.

You will usually see a hook echo. On a Doppler radar, it’s a red area that looks coma shaped. Otherwise, there can be a debris field or the wind shear will show up moving in opposite directions as large red areas.
