Abstract: Neither Henri Poicaré nor David Ruelle ever saw any contradiction between chance and determinism. What, then, is a random variable? Where does stochasticity come from? How can we use centuries of theory, observations, and modeling to inform state-of-the art General Circulation Models? I will address, if not completely answer, these and other questions in a somewhat random walk through issues in stochastic climate modeling. See more details MPE Weds (inc.

SGS distributions are associated with damped linear Markov processes perturbed by asymmetric stochastic noise and as such represent the simplest physically based prototypes of the observed distributions. As is true in most dynamical systems, an ensemble-mean forecast based on this process is generally not the most likely forecast, and the forecast uncertainty depends on the initial conditions, even when the initial conditions are perfect. Further, the heavy tails associated with SGS distributions have large ramifications for prediction of extremes. In this talk, I will discuss these and other annoyances. See more details •	6

When it rains, spatial variation in the soil infiltration rate leads to the formation and reabsorption of rivulets on the surface, and local topography determines the coalescence of rivulets. We consider the question of how coalescence facilitates overland flow using a highly abstracted version of the problem, in which the drainage pattern is represented by a Galton-Watson tree. We show that as the rate of rainfall increases there is a distinct phase-change: when there is no stream coalescence the critical point occurs when the rainfall rate equals the infiltration rate, but when we allow coalescence the critical point occurs when the rainfall rate is less than the infiltration rate, and increasing the amount of coalescence increases the total expected runoff.
