p_rgh outlet boundary condition for atmospheric simulation

Hi all, can someone help me?
I'm having trouble understanding boundary conditions for p_rgh. For example, I'm using the buoyantSimpleFoam solver to simulate atmospheric conditions. To sum up, the flow with buoyant effects.
At first I created a great computational domain, with height of 200 m. For now, I set every face as a walll except inlet and outlet. For inlet, I specified:
uniform value (10 0 0);
I am in doubt about what boundary conditions I will need to specify for the outlet.
Because p_rgh presents a small variation along the z-axis, the axis of gravity direction. I understand that p_rgh = p - rho.g.h, so there would be no change in the direction of g, right?
