本文研究表明，对于给定的导风云图序列，如果示踪云在给定时间间隔内的位移小于两个像距，适用傅立叶相位分析法计算云迹风；

Studies in this article show that if the displacement of target cloud is less than two pixels, Fourier analysis technique is an appropriate method of computing CMW.

对用该方法选取的示踪云进行云迹 风 反演，然后对 反演出的云迹 风进行环流分析，并与探空 风进行比较。

Then cloud motion winds are derived from these tracers and after a circumfluence analysis on the cloud motion winds, the cloud motion winds are compared with the rawinsonde winds.
