Query: The global attractor of the 2D Boussinesq equations with fractional
  Laplacian in Subcritical case   We prove global well-posedness of strong solutions and existence of the
global attractor for the 2D Boussinesq system in a periodic channel with
fractional Laplacian in subcritical case. The analysis reveals a relation
between the Laplacian exponent and the regularity of the spaces of velocity and
temperature.
