Summary

A perturbation method is developed which will permit the calculation of inertial wave eigenfrequencies for a Poincaré model of the Earth's fluid outer core in which the rotation speed is non-uniform. The method is demonstrated by calculating the frequency for an axisymmetric wave in a cylindrical cavity using differential rotations obtained from a numerical model. The results indicate a sensitivity of the eigenfrequency shifts to the profile of the differential rotation. The relevance of the associated geophysical inverse problem is discussed.
