radar wind meaning in English
雷达测风
Examples
- Lastly radar wind field and radar humility field are assimilated in the mm5 4d variational assimilation system
最后把雷达风场和雷达湿度场同化到mm5四维变分同化系统中。 - The assimilation experimentation results indicate that after assimilating radar wind field of small spatial scale , mesoscale and small - scale precipitation prediction can be improved and mesoscale and small - scale information which ca n ' t appear by tradition datum can be gained , which is valuable to analyze the mesoscale and small - scale system structure ; the effect assimilating radar humidity field is n ' t obvious , which is perhaps correlation with precipitation types and assimilating time . the results also show that adding radar humidity field to initial condition at initial time can supply the gap of the regular data in reflecting the mesoscale and small - scale systems , strengthen the humidity in the initial field , and eventually help to improve precipitation . the experiment of assimilating radar wind field and radar humility field at the same time shows that vapor transportation and local vapor divergence play more significant role in causing excessively heavy rain than only high wet center
同化试验结果表明：同化空间分辨率很高的雷达风场后，能改善中小尺度降水的预报效果，并且能够得到常规观测资料所不能得到的中小尺度信息，对分析中小尺度系统结构具有重要意义；同化雷达湿度场效果不明显，可能与降水类型和同化时刻有关；而直接在初始时刻加入雷达湿度场，补充了常规资料在反映中小尺度系统方面的不足，增强了初始场中的水汽，有利于降水量的增加；同时同化雷达风场和雷达湿度场的试验表明，水汽的输送和局地的水汽辐合对于产生特大暴雨的贡献远大于仅有高湿中心的贡献。
