• An infiscid shallow rotaing ocean model with linearized bottom friction is considered to determine the frictional effects on the unsteady wave motions generated in the ocean by arbitrary as well as special atmospheric disturbances. The asymptotic solution is abtained for the free surface elevation due to stationary as well as travelling wind stresses. It is shown that the transient solution decays exponentially as t→∞ and the ultimate steady-atate solution describes standing and progressive long waves propagating upstream and downstream with exponentially damping amplitude. The indlusion of the bottom friction introduces the exponential damping factor into the amplitude, and makes other significant changes in the wave-structure as well as its various properties. The resonance-type effect on the wave motions observed in a frictionless ocean model is no longer present in this frictional model.
