How can shortwaves be identified and followed on 500 mb charts?
What will be the ideal response?
ANSWER: ?Sometimes it is difficult to pinpoint the location of a shortwave trough on a 500-mb chart simply by looking at the contour lines. However, with the aid of vorticity, it is possible to locate a shortwave on a map and determine how it will move. The shortwave aligns itself with the region of maximum vorticity. So where we find a vorticity maximum on the chart, we also find a shortwave trough.
