✦ Synopsis

The vorticity and temperature fields in axisymmetric thermals are studied via a projection method for the Navier-Stokes Boussinesq equations. Development of small-scale structure is observed at high Grashof numbers, and spreading rate, entrainment, mixing in the core, and generation of countersign vorticity are enhanced.
