 Solution

To return the broad interior transport, the western boundary current has opposite sign and characteristic peakThe leading exponential profile retains the smaller interior offset, $v(0)\simeq (F_0/\beta )(1-L/{\delta }_W)\simeq -52.1\mathrm{m}{\mathrm{s}}^{-1}$. Because $\gamma L\simeq 0.593$ is not very small, the exact two-wall solution gives a more accurate linear-model peak:All three evaluations identify an intense southward western boundary current, with peak at $x=0,y=0$, of order tens of metres per second. They are predictions of the stated steady linear barotropic model. Nonlinear advection, stratification and the actual basin geometry could alter them substantially; the calculation does not establish that real Pluto winds attain these values.
