**Title:**Coupled boundary layers for the primitive equations of atmosphere.

**Abstract:** In this talk I will discuss the boundary layers problems of the primitive equations of
atmosphere. It is proved that, for well-prepared initial data, the smooth solutions
of the primitive equations converge to smooth solutions of quasi-geostrophic
equations as the Rossby number, the vertical viscosity and the vertical heat
conductivity tend to zero. The new ingredient is that the velocity boundary layer and thermal layer are considered
simultaneously.
