Abstract

We study dynamical behavior of local structures, such as sources and holes, in traveling wave patterns in a very long (2 m) heated wire convection experiment. The {\em sources} undergo a transition from stable coherent behavior to erratic behavior when the driving parameter ϵ\epsilon is {\em decreased}. This transition, as well as the scaling of the average source width in the erratic regime, are both qualitatively and quantitatively in accord with earlier theoretical predictions. We also present new results for the {\em holes} sent out by the erratic sources.
