observation field meaning in English
露天观测场地
野外观测
Examples
- Because the system error is ineluctable for mode , it is necessary to correct the simulation fielde effectively . in this paper , based on the idea of combined eof correction , the interannual simulation of sea surface wind stress anomalies of the tropical pacific ocean by lap two - level atmosphereic model have been corrected , result of corrected erperiment shows that the corrected field is more similar to the observation field , especially on the distribution of the space . three prediction experiments also shew that correcting scheme of combined eof can improve the interannual prediction veracity of model
在本文中，基于“联合自然正交展开误差订正”的思想，将中科院大气物理研究所两层大气环流模式输出的热带太平洋海表风应力异常的跨年度模拟场进行订正，订正试验的分析结果表明，订正后的热带太平洋海表风应力距平场与相应观测场年际变率分量的相似程度远远好于模式模拟的结果，尤其是在空间分布方面的改善非常显著；三组跨年度订正检验结果也表明，订正后的跨年度预测结果明显好于模式的预测结果。 - Abstract : digital basinis made from digital elevation model considering spatial variability within a catchment . on the basis of digital basin , the digital approach to describing hydrological processes within a catchment is investigated . digital hydrological model is regarded as a modern physically - based modeling technique that includes a large amount of information . the case study on the shiguanhe catchment in the huaihe river basin , intensified observation field of gewex asian monsoon experiment project , has shown that the digital mode lperforms very well not only in simulating runoff processes at any specific site , but also in simulating spatial distribution and temporal variation of hydrological elements and state variable ( especially soil moisture ) , if compared with traditional hydrological models . that provides solid foundation for full use of now available observation in formation and in - depth mining of hydrological data
文摘:考虑流域下垫面空间变异性,基于数字高程模型构建了数字流域,并在此基础上对描述流域水文物理过程的数字方法进行了探讨.文章认为,数字水文模型是一种有物理基础的包含大容量信息的现代模拟技术.史灌河流域实例研究表明,数字水文模型可以十分方便地输出水文要素和状态变量的空间分布与时间序列,这对充分利用现有观测信息进行水文信息的深层挖掘创造了条件
