一种中尺度滤波方法及其在卫星资料个例分析中的初步应用

A Meso-scale Filtering Method and Its Preliminary Application to the Case Analysis of Satellite Sounding Data

摘要: 本文提出一种“修正的双傅氏级数”滤波方法，应用卫星资料个例，与Barnes带通滤波法进行了对比试验。初步结果表明：用本文的方法分析得到的中尺度系统，结构更清晰，强度更强。

Abstract: A “modified double Fourier-series” filtering method is presented and applied to the separation of meso-scale waves from satellite sounding data. The comparative study of this method and Barnes band-pass filtering method shows that the effect of the former is superior to that of the latter.
