摘　　要：统计插值客观分析由于其具有综合不同类型观测资料的能力、并较适合于四维同化而越来越广泛地被许多国家用于业务。 本文用统计插值方法对多层高度场及风场客观分析从技术处理、参数调整到多种方案的选择作了一系列的试验研究,得出了较优越的格式和方案。A series of experiments of height and wind field statistical objective analysis has been made, coming to the conclusions that the analysis scheme is effective; the statistical interpolation is better than the correction method; some parameters, for instance, the number of observations included in the grid estimate, the influence radius and the first guess field, are not sensitive to RMS differences between the analyzed and observed values; and the Gaussian correlation model is more effective than the damped cosine model.
