摘要
为了更好地应用多普勒天气雷达精细的空间分辨力和快速的数据更新能力,文章对精细化多普勒天气雷达在强对流天气过程中的识别应用进行了研究,结果得出精细化雷达产品能够提高产品像素与像素间的连续性,使雷达回波更接近实际情况。精细化的雷达更能够抓住雷达产品的极端值,更好地观测到大风速区的精细结构,有利于得出雷暴大风出现的可能性,在识别龙卷时TVS特征参数比较明显。升级后的精细化多普勒天气雷达对中小尺度强对流回波监测和识别的能力有了较明显的提升,同时提高了短时临近预报的准确性。
In order to better utilize the fine spatial resolution and fast data updating capability of Doppler weather radar,the article studied recognition application of refined Doppler weather radar in severe convective weather processes.The results show that refined radar products can improve the continuity between product pixels and pixels,making the radar echoes closer to the actual situation.Refined radar can better capture the extreme values of radar products,observe the fine structure of high wind speed areas,and determine the possibility of thunderstorm and strong winds.TVS characteristic parameters are more obvious when identifying tornadoes.The upgraded refined Doppler weather radar has significantly improved its ability to monitor and identify medium and small-scale strong convection echoes,while also enhancing the accuracy of short-term forecasting.
