Sorry I post a lot of questions here, but I just can't find the answers anywhere else because I sometimes don't know what to search and I know you guys will know but anyways heres a few questions I have about radar:
1) I was thinking about this but couldn't come to a conclusion; the radar starts at 0º and slowly spins to 360º I assume so shouldn't there be a line where products don't line up correctly in between the 0º and 360º radial due to time differences? Iv'e never seen this so it certainly must not be the case but I'm curious as to what is. (looking for a somewhat more detailed account of what goes on during that 4.5 minutes or whatever the VCP time is.)
2) Occasionally I see small areas of lower reflectivity extending from the radar in opposite directions, primarily at night due to greater amounts of lower reflectivity, that are usually perfectly parallel or perfectly perpendicular to the wind fields in the velocity product at the time. Could anyone explain why this is because I can't exactly wrap my head around it.

3) I have seen this only a few times and it is easier shown than explained but in short, there are small waves on reflectivity with corresponding alternating velocity directions on the velocity and I have no idea what they are...gravity waves, large horizontal vortices maybe? Does anyone know what they are and what their significance is. Also, are these related to the northward moving bands of low reflectivity seen in the warm sector leading to south-westward moving storms along or ahead of the cold front? (don't know what those are or what they are called either!)

I also have a loop but was unsure how to attach a video.
Thanks for any input as it is greatly appreciated!!!
