V-
ARPS model variable: Velocity in the y-direction at a given point (m/s).
Variational objective analysis-
An objective analysis technique used to create an estimate of the atmospheric state that maximizes (or minimizes) a mathematical measure of desirable (or undesirable) characteristics. The analysis characteristics usually include measures of the fit to data, background field, and dynamical constraints.
Vbar-
ARPS model variable: Base state velocity component in the y-direction (m/s).
Veg-
ARPS model variable: Fraction of ground surface covered by vegetation.
Vegtyp-
ARPS model variable: Index of vegetation type.
Vertical altitude-
A measure or condition of height, especially of great height in the vertical direction.
Vertical dust flux-
Rate of flow of dust in the vertical direction.It is often estimated using a gradient method and the flux equation and it is used to develop and validate estimates predicted in wind and aerosol dispersion models.
Viscosity-
The transport of mass motion momentum solely by the random motions of individual molecules not moving together in coherent groups. Viscosity is a consequence of gradients in velocity fields in fluids. Sometimes described as fluid friction because velocity gradients in fluids are damped as a consequence of viscosity.
Vsflx-
ARPS model variable: Surface flux of v-velocity momentum
