Dear Jim

You could put "latitude: mean" for latitude if that is more representative
of what you have done. I assumed that you had calculated the mean latitude over
the whole area of the cyclone, which might imply giving equal weight to each
element of area rather than to each latitude. I don't have a clear picture of
what the calculation is and I think the distinction is quite subtle. The
cell_methods is not a detailed record of processing. It doesn't record anything
in a standardised way about weighting, for instance, but you can describe that
in the () comment.
