Abstract
The spatial and temporal bifurcations to chaos and dimensionality of strange attractors in Rayleigh-Benard convection are studied in an extended rectangular container with aspect ratios 15.0 and 1.0. With increasing Rayleigh number, oscillatory states, quasiperiodic states, and chaotic states are observed where the amplitudes of various modes strongly depend on the spatial position. The chaotic states just above the onset are characterized by low-dimensional attractors and the correlation dimension of the attractor is investigated as a function of Rayleigh number.
