Other Considerations
- With both patterns, the comma tail is associated with the warm conveyor belt. Vorticity advection will be minimal in this region. The comma tail begins at the upstream long wave trough.
- It is very important to remember that all satellite features are generated by system-relative motions.
- If moisture elements on the poleward side of the cyclonic circulation are stationary or moving westward with respect to the earth's surface, the vorticity maximum is actually a closed upper low or cold core low.
