Suppose there is a region of maximum absolute vorticity at position M on the chart in Fig. 12.31.

(a) How would the absolute vorticity be changing with time as an air parcel moves downstream (from position M) with the flow?

(b) Based on absolute vorticity, circle on the map where you would expect to find upper-level divergence, surface convergence, and a developing mid latitude cyclone.

(c) Draw a dashed line where you would expect to observe a shortwave trough.
