Dear Alison and Siobhan Sorry for late comments on the cryosphere names.
I commented this week on "shear". I was wrong to suggest that sea ice shear is like wind speed shear, because the latter is the vertical derivative of a horizontal speed, whereas sea ice shear is (I think) a horizontal derivative of a horizontal velocity or speed. I wonder what the quantity required is symbolically? Is it du/dy or dv/dx? These, I think, are two distinct components of a tensor, but I might be wrong. > Perhaps the name should be > tendency_of_fractional_growth_in_ice_volume_due_to_ridging or > tendency_of_fractional_growth_in_ice_area_due_to_ridging. > > I think we need to call the quantity a tendency because that is the term we > normally use in standard names to mean the time rate of change. I agree that it should be a tendency, and I suspect the quantity could be called tendency_of_sea_ice_area_fraction_due_to_ridging which is a contribution to (or perhaps identical with) the existing quantity tendency_of_sea_ice_area_fraction_due_to_dynamics Best wishes Jonathan _______________________________________________ CF-metadata mailing list CF-metadata@cgd.ucar.edu http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
