示踪云 meaning in Chinese
target cloud
Examples
- Time of passage of tracer cloud
示踪云通过时间 - An important step in deriving winds from geostationary meteorological satellite data is selecting the clouds which move slowly and go with the wind , which is called tracers
摘要云迹风反演中的一项很重要的工作是选取随风移动、变化缓慢的云，即示踪云。 - 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
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。 - By 1 - d fourier transform , we could analyze wave spectrum and get wave speed by computing phrase shift , then calculate the velocity of the wind , so we can avoid the problem of " sub - pixel motion "
使用傅立叶相位分析法，对示踪云进行频域波谱分析，由谐波的相位变化计算波速，继而得出风速，能够避免“亚像素尺度位移”问题，提高导风的精确度。
