The mаp аbоve shоws 500 millibаr geоpotential height contours. When examining the trough over the Pacific Northwest, we might be interested in identifying the labeled point that has the greatest relative vorticity. Develop a discussion that details the relative vorticity characteristics at each of the labeled points. As part of your discussion, rank the labeled points in order of least amount of relative vorticity to greatest and justify your answer using the components of the relative vorticity equation shown below.
