Abstract: We consider the Oberbeck–Boussinesq system with non-local boundary conditions arising as a singular limit of the full Navier–Stokes–Fourier system in the regime of low Mach and low Froude numbers. The existence of strong solutions is shown on a maximal time interval $[0, T_{\mathrm {max}})$. Moreover, $T_{\mathrm {max}} = \infty$ in the two-dimensional setting.
