symmetric instability

Similar to inertial instability but due to imbalance between pressure gradient and inertial forces for infinitessimal disturbances that meridionally displaces fluid along isentropes (in atmosphere) or isopycnals (in ocean). For geostrophic motion in the Northern Hemisphere, symmetric instability may occur only if the potential vorticity is negative.
