Hi Nan,
I thoroughly understand what you are proposing and that the proposed names are not affected. Your suggestion does potentially affect existing wave Standard Names outside the proposal and so I'm simply asking to park this consideration until after the current proposals are through the system to make managing the process easier. OK?
Cheers, Roy.

Hi Roy -
I didn't mean to change the 'names themselves', just the order of the
sentences in
some of the new definitions. Sorry if this wasn't clear.
So, for example, the proposed new definition for
sea_surface_swell_wave_to_direction is:
"To_direction" is used in the construction X_to_direction and indicates
the direction towards
which the velocity vector of X is headed. The direction is a bearing in
the usual geographical
sense, measured positive clockwise from due north. Swell waves are the
low frequency portion
of a bimodal wave frequency distribution.
and I am suggesting it be slightly tweaked to:
Swell waves are the low frequency portion of a bimodal wave frequency
distribution.
"To_direction" is used in the construction X_to_direction and indicates
the direction
towards which the velocity vector of X is headed. The direction is a
bearing in the usual
geographical sense, measured positive clockwise from due north.
Is that what you thought I was proposing? It seems like a minor change,
to me. I
don't think it needs to be done to every variable, just the ones that
are being
updated under your proposal and that include a definition of the 'main
term' in
the proposed definition.
Thanks - Nan
