Testing for Dynamical Dependence: Application to the Surface Mass Balance Over Antarctica
Dynamical dependence between key observables and the surface mass balance (SMB) over Antarctica is analyzed in two historical runs performed with the MPIâ€ESMâ€P and the CESM1â€CAM5 climate models. The approach used is a novel method allowing for evaluating the rate of information transfer between o...

Dynamical dependence between key observables and the surface mass balance (SMB) over Antarctica is analyzed in two historical runs performed with the MPIâ€ESMâ€P and the CESM1â€CAM5 climate models. The approach used is a novel method allowing for evaluating the rate of information transfer between observables that goes beyond the classical correlation analysis and allows for directional characterization of dependence. It reveals that a large proportion of significant correlations do not lead to dependence.
