Trying to test this, but I've hit a snag at the ipynb stage. Can someone confirm that

$$
\begin{align}
\frac{\partial v}{\partial t} + u \frac{\partial v}{\partial x} + v \frac{\partial v}{\partial y} + w \frac{\partial v}{\partial z} + fu = - \, \frac{1}{\rho} \, \frac{\partial p}{\partial y}
+ A_v \, \frac{\partial^2 v}{\partial z^2} + A_h \, \nabla^2 v
\end{align}
$$

works in jupyter? The jupyter parser adds a nested equation environment that mathjax chokes on.

Yep, just tried it and it works OK.

Though I just added $$ around the latex addition in this PR, and that also worked fine. I also tried the version you just gave and, with this PR, it worked fine too...

ok -- must be the latex notebook extension I've installed in jupyter that's getting in the way

OK cool - I'm gonna merge this away and we can spot-check bugs if they come up
