#39

Change Date: 15 Aug 2024, 12:03 p.m.

Term: **northward_friction_velocity_at_sea_water_surface**

Unit: m s-1

Unit ref: UVAA

AMIP:

GRIB:

"Northward" indicates a vector component which is positive when directed northward (negative southward). Friction velocity is a reference ocean velocity derived from the relationship between ocean density and downward stress and is usually applied at a level close to the surface where stress is assumed to be independent of height and approximately proportional to the square of mean velocity.
