W-
Vertical component of the wind velocity (m/s).
Wbar-
ARPS model variable: Base state vertical component of the wind velocity.
Wetcanp-
ARPS model variable: Amount of water present on the vegetation canopy.
WRF (Weather Research and Forecasting Model)-
A non-hydrostatic mesoscale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs. It features multiple dynamical cores, a 3-dimensional variational (3DVAR) data assimilation system, and a software architecture allowing for computational parallelism and system extensibility. WRF is suitable for a broad spectrum of applications across scales ranging from meters to thousands of kilometers.
