To account for atmospheric model uncertainties in the seasonal forecasting system based on CNRM-CM (Voldoire et al. 2013), two stochastic perturbation methods have been introduced in the ARPEGE-Climate atmospheric model, namely:
We present here separate assessments of the impact of these methods on seasonal forecast quality.
