Created: Feb. 8, 2021
Proposer: Andy Saulter
Proposed Date: 2021-02-01

Term: northward_friction_velocity
Unit: m s-1
Unit ref: UVAA
AMIP:
GRIB:
A velocity is a vector quantity. "Northward" indicates a vector component which is positive when directed northward (negative southward). Friction velocity is a reference wind velocity derived from the relationship between air density and downward stress and is usually applied at a level close to the surface where stress is assumed to independent of height and approximately proportional to the square of mean velocity.
