0 an area of high atmospheric pressure that causes calm weather:
Anticyclones cause cloudless blue skies and high temperatures in summer.
The cyclones are discernably stronger than the anticyclones, implying the presence of a cyclonic shear over the forcing region.
Dotted lines correspond to cyclones, and solid lines to anticyclones.
When friction is present, the stationary field has a component with anticyclones (high pressures) on the westward sides of the crests.
The potential flow is then away from the source point and an anticyclone forms.
An anticyclone leads to pumping (as sketched), a cyclone to suction.
A large-scale dipole vortex splits into two monopoles (a cyclone and an anticyclone), where a vortex of one polarity is long-lived whereas the vortex of the opposite polarity disperses.
In this case, the vortex patches in each layer merged and formed a single, motionless connected rotational vortex structure consisting of an upper-layer anticyclone and a lower-layer quasielliptical cyclone.
Two main methods of generation were identified : viz, the use of sources and sinks to produce anticyclones and cyclones, respectively, and vortices produced by stirring a localized region.
