Phase diagram showing the evolution of the last 40 days of observations along with the 32 day ensemble ECMWF forecast from the seasonal forecast system with a model based climatology (the climatology used is determined by model hindcasts and not observations and is a function of model lead time). This data is updated once per week on Thursday. The yellow lines are the 51 ensemble members and the green line is the ensemble mean (thick-week 1, thin-weeks 2-4). The dark gray shading depicts 50% of the members fall in this area and the light gray shading indicates 90% of the members.
