Vorticity refers to the spinning or rotation of a fluid, such as air or water. It measures the strength and direction of this rotation, telling us how much a fluid is swirling or twisting at any given point. The concept of
vorticity is important in fields like fluid dynamics and meteorology where understanding the movement of fluids is crucial.

Role
of vorticity mixing in the maintenance of surface winds.
This is consistent with regional patterns of
potential vorticity anomalies, which, as discussed, may be associated with Rossby wave breaking and western boundary currents.
Below is a plot of
relative vorticity for a single day simulated by CAM5 with pre-industrial forcing, which has been computed by uv2vrF.

vorticity dynamics.
EETCs are tracked from relative
vorticity using an objective feature tracking algorithm.
As meridional potential
vorticity mixing is inhibited across the jet, a discontinuity is created between weakly stratified air on its warm side and strongly stratified air on its cool side.
These cascades can be modified or halted, for example, by friction, a background
vorticity gradient or a mean temperature gradient.
The same region is also projected to experience a small intensification of explosive cyclones, with
larger vorticity values for models that predict stronger increases in the speed of the jet stream (R = 0.58).
I noted the data (independent data not depending on the identification of the intensity of tropical storms) indicates that there is no trend in all but one of the necessary conditions of cyclogenesis (wind shear, large
scale vorticity and etc: see Hoyos et al. 2006) and that these parameters change only on interannual time scales.
Ascending clouds create turbulences that cause
stronger vorticity or changes in trajectory.
In particular, the formation of shocks and the consequent a) departure from local thermal equilibrium, which may be important for baryogenesis, and b) the generation of
vorticity which may be important in the origin of primordial magnetic fields.
This area of
vorticity served as a focusing mechanism for moisture lift and advection (movement) from the Gulf of Mexico consistently replenishing the available precipitable water.
For forecast models these errors can be overcome by continually inserting new vertical component of
vorticity observational data every 6 hours, thus reducing the error that has spread upward from the erroneous boundary layer.
Significant enhancement in low level
cyclonic vorticity and mid-troposphere humidity during La Niña years compared to El Niño years when the PDO was in warm phase, rather than the PDO was in cold phase leads to this difference.
Below are animations of the zonal wind and
vorticity at the level in the model that corresponds roughly to the estimated level of the cloud tops from which the observed flows are inferred.
Using piecewise potential
vorticity inversion, I show that the lower level contributes most to maximum ETC intensification (52 %), followed by the upper level (26 %), and the surface (22 %).

Meteorologically speaking, that
extra vorticity — literally a measure of energy causing the atmosphere to form complex features at the local level — could bring a foot of snow in only a few hours over very narrow strips.
Enstrophy diagnostics show that when the condition of a
negative vorticity gradient is met, the effects of barotropic instability are indeed more prevalent.
The business of doing successful real estate transactions is not based in science or mathematical dynamics, but if thought about in the realm of
vorticity curves, as Brian often notes, ORE puppy mill procedures might be differently arranged.
A review of observations, theory and modeling is presented to support the claim that strong anticyclonic
relative vorticity can also lead to CAT through the generation of gravity wave activity by geostrophic adjustment and inertial instability.
Finds that, in the Atlantic, potential intensity, low -
level vorticity, and vertical wind shear strongly covary and are also highly correlated with sea surface temperature, at least during the period in which reanalysis products are considered reliable

It works not by spinning in the wind, but by taking advantage of a phenomenon
called vorticity, or the Kármán vortex street, which is a «repeating pattern of swirling vortices.»
