Dear Jenny and Jonathan,
I think agreement has been reached on using
sea_surface_wave_period_at_variance_spectral_density_maximum for the
required quantity. This is accepted for inclusion in the standard name
table with units of seconds and the definition that Jenny originally
provided: "A period is an interval of time, or the time-period of an
oscillation. The peak wave period is the period of the most energetic
waves in the total wave spectrum at a specific point."
I note the subsequent discussion with comments from Roy and Bert
regarding the use of 'mean' in existing wave period names. I need to
digest this information some more before deciding whether we need to
change the existing names.
Best wishes,
Alison
