precipitation echo

基本解釋

The results can help analysis echo of multi-wavelength and understand process of cloud precipitation correctly.
在實際工作中，分析多波長雷達(dá)的回波時，這些討論結(jié)果對分析和理解云降水過程有幫助。
It is shown from analysis that the Precipitation ahead of cold front was about 92% of total surface rainfall, and made of four echo clusters.
結(jié)果表明：冷鋒鋒前的降水約占全部降水的92％，鋒前降水由四個回波團(tuán)組成。
Non-precipitation echo from radar such as ground objects echo and super refraction and so on are important to explore quantitatively precipitation and the other products.
地物和超折射等非降水回波是影響雷達(dá)定量探測降水和其他產(chǎn)品的重要因素，利用降水和非降水回波反射率三維結(jié)構(gòu)特征可以對雷達(dá)數(shù)據(jù)進(jìn)行質(zhì)量控制。
