| Session Description | Forecasting the behavior of the atmosphere at seasonal, inter-annual and decadal time scales is opening new challenges due to the increasing role played by the coupling with the other components of the climate system for these long lead times. It is therefore crucial to understand the impact of coupling on the variability and predictability of the atmosphere on long time scales. This session is devoted to the compilation of the recent progresses on this topic, either from state-of-the-art models, time series analysis, or from more theoretically-oriented approaches based on dynamical systems theory and stochastic modelling. The main purpose is to bring several communities together in order to develop new ideas through cross-fertilization. More specific aspects could be: - Investigation of the impact of coupling on the variability in tropical and extra-tropical regions (ENSO, MJO, NAO…) derived from state-of-the-art Earth System Models and observed or reanalysis data sets; - Investigation of the dynamics induced by the coupling of multi-scale systems based on tools developed in the context of dynamical system theory; - New challenges of data assimilation in coupled models; - Insights of the fundamental limits of predictability and analysis of the relevant initial error dynamics and model error physics and methods that attempt to quantify the predictability. |
