蒲朝霞 , . 数据同化在气候模拟中的应用——对中国西部区域气候研究的展望[J]. 地球科学进展, 2007 , 22(11) : 1177 -1184 . DOI: 10.11867/j.issn.1001-8166.2007.11.1177
Modern data assimilation techniques represent a way to combine the numerical model and observations together for an optimal estimation of the state of the earth system. In addition to their vital role in numerical weather prediction and climate reanalysis, data assimilation techniques can also be applied in many aspects of climate study, such as model initialization, validation and optimization. The paper gives a brief discussion on the applications of data assimilation in climate modeling with emphases on a few key issues that are closely associated with the regional climate study over the western China. Challenges, potential methodologies, recent results and future development are presented.
