英文摘要Inertial oscillations, inertial waves and the initial value problem in a rotating annular channel are investigated for an arbitrarily small but fixed Ekman number E. We first derive the inviscid solution of inertial oscillations and inertial waves, as well as an asymptotic expression for the viscous decay factors valid for the inertial modes of a broad range of frequencies that are required for an asymptotic solution of the initial value problem. A time-dependent asymptotic solution of the initial value problem subject to a physically acceptable initial condition is then obtained. We also perform a fully numerical analysis to estimate the viscous decay factors and to simulate time-dependent solutions of the initial value problem, showing satisfactory quantitative agreement between the asymptotic analysis and the fuller numerics.
