Statistical state dynamics (SSD) has recently proven useful in providing insight into physical mechanisms underlying the dynamics of turbulence in atmospheres at planetary scale. In SSD statistical quantities are taken as the dynamical variables and the dynamics of the statistical state is typically closed at second order. Using SSD allows analytical expressions to be obtained for aspects of the dynamics of turbulence that have well recognized manifestation in both observation and simulation, but lack analytical expression in the dynamics of single realizations of turbulent states. Example applications to the climate of the Earth and outer planets will be presented.
