1) non-precipitation velocity echo
非降水速度回波
2) Non-precipitation echo
非降水回波
1.
Non-precipitation echos were few Researched with restrict to detectivetechnique and data, because it is too weak to be detected by traditional radar.
这种回波的产生可能是由于在近地面处有逆温,逆温中潮湿的地面使水汽压随高度变化很大,导致了折射指数随高度变化很大;也可能是近地层湍流或者上空有云回波,由于多普勒雷达灵敏度很高,往往产生非降水回波,其多普勒速度特征反映了雷达站周围环境风场的结构。
2.
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响雷达定量探测降水和其他产品的重要因素,利用降水和非降水回波反射率三维结构特征可以对雷达数据进行质量控制。
4) echo wave speed
回波速度
1.
Interpreting and emulating echo wave speed based on common characteristics of driving behavior;
基于驾驶行为共性的回波速度解释及仿真
5) Mixing clouds echo
混合降水回波
6) features of precipitation echo
降水回波特征
