    "abstract": "A model for the large-scale circulation (LSC) dynamics of turbulent\nRayleigh-Benard convection is presented. It consists of two stochastic ordinary\ndifferential equations motivated by the Navier-Stokes equation, one each for\nthe strength and the azimuthal orientation of the LSC. Stochastic forces\nrepresent phenomenologically the action of the turbulent fluctuations on the\nLSC. Without adjustable parameters, the model yields a meandering LSC with\noccasional rotations, and with more rare cessations that occur a few times per\nday -- differing only by about a factor of two from experiment. Also as in\nexperiments, the distribution of LSC orientation-change is uniform for\ncessations and a power law for rotations.",
