Figure 7.25a
Solution of the two-dimensional equations for the parameters in Table 7.1
corresponding to run 1. Plotted in (a) are contours of the stream function at four uniformly
spaced times in the sequence: upper left, upper right, lower left, and lower right. The
horizontal axis is the x direction and the vertical axis is the z direction. The parameters for
the run are

closed contours just above the center line correspond to a flow rotation in the clockwise
direction and the contours just below the center line correspond to counterclockwise
rotation. [After Seyler (2005). Reproduced with permission of the American Geophysical

one should note that because of the periodic boundary conditions the waves that
go out the right boundary emerge from the left boundary.
Figure 7.25b is the potential temperature perturbation for the same times
shown in Fig. 7.25a. Note that almost all of the potential temperature pertur-
bation occurs in the layer while the flow can extend well beyond the layer. The
closed contours just above the center line correspond to a flow rotation in the
clockwise direction and the contours just below the center line correspond to
