slantwise convection

A form of convection driven by a combination of gravitational and centrifugal forces.

Slantwise convection can occur in baroclinic flows in which the slantwise-upward displacement of air parcels, elongated in the direction of the thermal wind, results in a vector combination of buoyancy and Coriolis (or centrifugal) and pressure-gradient accelerations that drive the parcel in the same direction as the displacement.
See also symmetric instability.
