中文摘要: 对TOVS和云导风非常规反演资料进行了质量控制,并将控制后的反演场与常规观测资料以及T106分析场资料进行变分同化,得到合成分析场。结果表明:在合理的目标函数设计的基础上,合成分析场与仅用常规探空资料相比更接近于实况,弥补了实况资料的不足。运用MICAPS中特有的网格点绘图功能实现了机器自动绘制历史天气图工作。经检验误差较小,线条平滑。该方法为在实时天气图和历史图分析中使用非常规资料提供了一条新的途径,具有一定的实用价值。

Abstract:The scheme is designed to describe the composite assimilation analysis field of satellite retrieval data,conventional observations and T106 analysis field. Results show that the composite analysis field is more similar to the actual atmospheric condition and make up the lack of the observations based on the reasonable design of the objective function,in contrast to the conventional radiosonde observations. It is found that the error is smaller and the isoline is smooth.
