摘要：

A mathematical model of convection obtained by truncation from the two-dimensional Boussinesq equations exhibits a bifurcation from symmetrical cells to tilted non-symmetrical ones. A subsequent bifurcation leads to time-dependent flow with similarly tilted transient plumes and a large scale Lagrangian mean flow. Although not intended as a description of turbulent convection, the model brings out the possibility of the spontaneous change of symmetry suggested by the experiments.
