Hi Karl,
It would be far clearer to me if the same construct established for mean wind velocity were applied to gust wind velocity and I would prefer it if the existing constructs (used for currents as well as winds) were left as they are.
So, my preference would be for Stephane's suggestion to be accepted.
Cheers, Roy.

Subject: Re: [CF-metadata] Standard name for direction of wind gust
Hi,
I think it is better if the construction of this new standard name is
similar with the construction of other ones.
Of course we can discuss if we want to change all the existing
from/to_direction standard_names, but it may take a lot more time to
reach an agreement (On my side, I don't really have an opinion on the
subject. from/to_direction may not be the best construction, but I think
it is clear about what it represents)
I hope that, for the moment, this discussion won't prevent the creation
of this new standard_name !
Best regards
St?phane Tarot
