On the evolution & equilibration of submesoscale fronts
… activity. Submesoscale fronts are susceptible to symmetric instability — a form of convective–inertial instability which occurs when the potential vorticity is of opposite sign to the Coriolis parameter. Symmetric instability is characterised by growing slantwise convection cells nearly aligned …

Synoptic and Mesoscale Dynamics of Snowbands in Winter Cyclones
… similar to radar observations; (2) Conditional symmetric instability did not contribute to the formation of the narrow bands, rather, the release of potential instability at the interface of the dry slot and the trowal led to the development of upright convection and initiated the narrow bands. …

The Formation and Impact of an Incipient Cold-Air Precipitation Feature on the 24-25 January 2000 East Coast Cyclone
… the IP formed in a region of elevated convective symmetric instability (a mixture of gravitational conditional instability and conditional symmetric instability) where forcing for ascent was provided by an approaching upper-level trough/jet streak. Short-range forecasts from NWP models …

The evolution and breakdown of submesoscale instabilities
… particular, we will investigate the way in which symmetric and ageostrophic baroclinic instabilities interact when simultaneously present in a flow, with focus on the growth rates and energetic pathways of previously unexplored dynamic instabilities that arise in this paradigm; three-dimensional, …
