SummaryThe transition to turbulence in a fast moving fluid often starts from a localized turbulent seed that grows until it fills the whole domain. Methods stemming from dynamical systems theory allow first steps towards understanding the observed spreading: Recently constructed special solutions of the underlying equations capture aspects of the characteristic spatiotemporal dynamics. The new solutions are created by known pattern formation mechanisms also believed to underlie the characteristic spots and stripes on leopards and tigers.
