Summary The two‐dimensional Boussinesq equations are integrated with given conditions on the velocity and static stability on the left‐hand boundary and with a deformed lower boundary, to give the transient gravity wave, or mountain wave. The results are compared with linear theory, and it is found that although in general the overall flow pattern agrees with the linear analysis, in the region near the obstacle the non‐linear boundary condition produces several important departures. Good qualitative agreement with observations is attained.
