Hello Jonathan,
I think the "mean" comes from the world of observations. Wave data are acquired with kit that takes multiple measurements so any parameterisation is subject to variance.
However, I have only ever seen means used and I have seen a great deal of inconsistency in whether the fact that the numbers are averages is labelled explicitly or not.
Cheers, Roy.

Dear Jenny
> sea_surface_wave_period_at_variance_spectral_density_maximum sounds good to me.
So that's a definite proposal, which Alison will consider I expect when she
has a moment. Meanwhile I expect you could carry on and use it.

I think it might be sensible to consider deleting "mean" in those existing
names, unless someone can remind us what it indicates - the definitions don't
suggest to mean why "mean" is useful in that context.
Cheers
Jonathan
