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

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。

A“modified double Fourier-Series”filtering method is presented and applied to the separationof meso-scale waves from satellite sounding data.The comparative study of this method andBarnes band-pass filtering method shows that the effect of the former is superior to that of the lat-ter.
