A new four-dimensional data assimilation method named 4DSVD based on attractor theory is introduced by Qiu and Chou(2006).
4DSVD是最近提出的一种新的资料同化方法。
One of the major difficulties in data assimilation is that the degree of freedom in NWP model far exceeds the number of observations collected at any single time,so the problem is usually underdetermined.
对Qiu和Chou(2006)提出的一种基于预报集合的降维资料同化方法(4DSVD)给出了可行的实施方案,利用中尺度模式MM5产生的模拟资料进行数值试验并将其与MM5/3DVAR的同化结果进行比较,分析了不同的观测误差和观测点密度对同化结果的影响。
GRAPES project is mainly focused on data assimilation,dynamical core,physical parameterization schemes,and infrastructure software.
中国气象科学研究院(灾害天气国家重点实验室)自2000年起,先后在科技部“973”重大基础项目“我国重大天气灾害形成机理和预测理论研究”和“十五”重点攻关项目“中国气象数值预报系统技术创新研究”支持下,主持承担了中国气象局新一代全球/区域多尺度通用同化与数值预报系统GRAPES(Global/Regional Assimilation andPrEdiction System)的研究开发,围绕着资料同化、模式动力框架、物理过程、大型软件工程等核心技术开展了自主创新研究,取得了非静力中尺度模式、三维变分资料同化、标准化、模块化、并行化模式程序软件等方面的突出成果,部分成果已在业务上得到了应用,显示了良好的技术性能和业务发展潜力。
