摘　　要：文章对自主研制的基于神威巨型机的并行化集合数值天气预报系统的研制背景、系统组成、主要技术特点和应用发展前景作了一简要介绍。The development background, structure and main technical characteristic of a parallel ensemble numerical weather prediction system on the Shenwei massively parallel processor system are described. The system is composed of seven subsystems: preprocessing, data assimilation, ensemble initial data generation, numerical weather prediction, post processing, product generation and visual real time monitoring control. The singular vector is used to create initial perturbation at the T21L19 resolution and the forecast subsystem is at the T106L19 resolution. The number of ensemble members is 32.
