Uncertainty or randomness is ubiquitous in climate and geophysical flows. Examples of such randomness are stochastic forcing, uncertain parameters, random sources or inputs, and random initial or random boundary conditions due to an uncertain environment. Taking stochastic effects into account is of central importance for the development of mathematical models of climate and geophysical flows. These mathematical models are in the form of stochastic ordinary or partial differential equations, and random ordinary or partial differential equations. Problems arising in the context of climate and geophysical flows have inspired interesting research directions in the fields of stochastic partial differential equations and random dynamical systems. I will present recent research on geophysical fluid dynamics under uncertainty, especially the stochastic dynamics of some coupled ocean-atmosphere models.
