曲面拟合客观分析方法中的滤波特性
The Filtering Technique with the Curved Surface Fitting Objective Analysis Method
-
摘要: 在一般区域上使用曲面拟合的方法进行客观分析时，所得的客观分析场具有良好的低通滤波效果。通过对比分析发现，使用曲面拟合的客观分析方法，其滤波结果能够较好地体现出中尺度环流系统与实际天气的对应关系。Abstract: The objective analysis fields obtained using the curved surface fitting in an area have a good property of direct low-pass filtering. In comparison with the other filtering results, it is found that its filtering results are better, and have a considerable corresponding relationship between the mesoscale circulation systems and the weather conditions
