DESCRIPTION:The unfolding of inertial instability in vortices in a uniform
 ly rotating and stratified fluid is studied through numerical simulations.
  The vortex dynamics during the instability is examined in detail. We demo
 nstrate that the instability is stabilized via redistribution of angular m
 omentum in a way that produces a new equilibrated vortex with a stable vel
 ocity profile. Based on extrapolations from the results of a series of sim
 ulations in which the Reynolds number and strength of stratification are v
 aried\, we arrive at a construction based on angular momentum mixing that 
 predicts the infinite-Reynolds-number form of the equilibrated vortex towa
 rd which inertial instability acting alone would drive an unstable vortex.
  The essential constraint is conservation of total absolute angular moment
 um. The construction can be used to predict the total energy loss during t
 he equilibration process.
