[CF-metadata] new standard_names for variables concerning sea surface waves

Dear Heinz and Beate

These concepts look to me like different statistical methods for characterising
the spectrum, and as such, can they be expressed by cell_methods? For instance,
if we define a standard name of
probability_density_function_of_sea_surface_wind_wave_period
we can express the "peak" period (I presume this is the mode of the pdf - is
that right?) with a standard name of sea_surface_wind_wave_period and a
cell_methods of
"probability_density_function_of_sea_surface_wind_wave_period: maximum"

I imagine that something like that could done for the others, but I am not
clear what the "mean" is over, or what "tm" means. "spread" also sounds like
a statistic of some kind, that would need definition, or is it perhaps a
standard deviation?

Cheers

Jonathan
