Periodic point vortex configurations can be used as reduced‐order models of vorticity‐dominated wakes behind bluff bodies. The staggered Kármán street is considered the canonical representation of these vortex wakes. However, the streamline topology of this configuration is structurally unstable. Slight variations in the intervortex separations cause fluid to wind through the street, which has implications for transport and mixing in vortex wakes. (© 2008 WILEY‐VCH Verlag GmbH & Co.
