Review of the Ensemble Prediction Using Stochastic Physics

Model uncertainty is an important aspect of theoretical research and operational application of ensemble forecast. The model uncertainty mainly comes from the mathematical simplification and finite numerical calculation of the atmosphere in time and space, and the imperfect structure of the physical process itself. The prevailing methods include multi-model approach, multiphysics approach and stochastic physics method. The purpose of this paper is to sort out the progress, application, methods, existing problems and other aspects of ensemble forecasting based on stochastic physical processes, sum up the relevant theoretical and technical results and scientific problems, and explore the future directions for work worthy of exploration and research, so as to provide reference for the in-depth application of stochastic physical ensemble forecast.
