atmosphere_helicity

under discussion
Created: Feb. 8, 2021
Proposer: Emily Schlie, Eric Engle, and the CAMPS team
Proposed Date: 2020-12-22
Change Date: Feb. 8, 2021, 2:56 p.m.
Term: atmosphere_helicity
Unit: m2 s-2
Unit ref:
AMIP:
GRIB:
One-half the scalar product of the velocity and vorticity vectors, where vorticity refers to the standard name atmosphere_upward_absolute_vorticity. Helicity is proportional to the strength of the flow, the amount of vertical wind shear, and the amount of turning in the flow.
