In this paper, we study the number of traveling wave families near a shear flow under the influence of Coriolis force, where the traveling speeds lie outside the range of the flowu. Under the-plane approximation, if the flowuhas a critical point at whichuattains its minimal (resp. maximal) value, then a unique transitionalvalue exists in the positive (resp. negative) half-line such that the number of traveling wave families near the shear flow changes suddenly from finite to infinite whenpasses through it. On the other hand, ifuhas no such critical points, then the number is always finite for positive (resp. negative)values. This is true for general shear flows under mildly technical assumptions, and for a large class of shear flows including a cosine jet(i.e. the sinus profile) and analytic monotone flows unconditionally. The sudden change of the number of traveling wave families indicates that long time dynamics around the shear flow is much richer than the non-rotating case, where no such traveling wave families exist.
