precipitation echo

基本解释

The results can help analysis echo of multi-wavelength and understand process of cloud precipitation correctly.
在實際工作中，分析多波長雷達的廻波時，這些討論結果對分析和理解雲降水過程有幫助。
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.
結果表明：冷鋒鋒前的降水約佔全部降水的92％，鋒前降水由四個廻波團組成。
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廻波是影響雷達定量探測降水和其他産品的重要因素，利用降水和非降水廻波反射率三維結搆特征可以對雷達數據進行質量控制。
