Uncertainty is unavoidable in weather and climate prediction, which gives rise to difficulties for societal decision-making, and meanwhile provides opportunity for developing the research of prediction. This note reviews the thoughts that have emerged in recent years towards the future development of the meteorological prediction system. And then it makes up an example to show how the user′s knowledge can be combined with weather forecasting based on decision-making theory. Finally, a conceptual framework of the future prediction system is proposed, which combines the meteorological models and the decision-making processes comprising risk assessments and other knowledge from various users.
