Abstract
In this paper, we obtain a refined blow-up criterion in term of vorticity of fluid for smooth solutions to the 3D Boussinesq system with no viscosity term in the velocity equation, this criterion may admit more singular vorticity than previous ones do. Particularly, it improves Fan’s results.
