✦ Synopsis

Spurious inertial oscillations are induced in boundary-layer models if a geostrophic wind is prescribed which changes in time. A simple technique is proposed to eliminate these oscillations. The scheme is successfully applied to idealized cases of boundary-layer flow and to a real situation where a pronounced turning of the geostrophic wind has been observed.

Egger and Schmid (1988) present an interesting discussion of inertial oscillations generated in 1-D boundary-layer models with imposed, time-dependent pressure gradients (geostrophic winds). They propose a scheme to eliminate the unwanted oscillations through a modification of the imposed pressur
