06.29.11: Mean PV along 60°W in OFES

Fig.1 shows the 2004-6 mean planetary and total potential vorticity (PV) along 60°W in the QuickScat OFES simulation. The PV is computed for isopycnal surfaces in such a way that if there were temporal or spatial variation, the PV would be uniform in time and space. First, there is little difference between the total and planetary PV. Second, we see several regions where PV appears to be homogenized in the horizontal and vertical.

Figure 1: (a) Planetary and (b) total PV computed along 60°W in the QuickScat OFES simulation for 2004-6. The horizonal dash line shows the reference depth used to compute the potential density. On the vertical axis of panel (b) are shown the mean depth of the set of isopycnal layers used.

Fig. 2 shows the standard deviation.
