    摘要:

    采用统计、相关分析等方法,对2014年济南站边界层风廓线雷达观测资料和L波段雷达探空资料进行了长期时空变化规律的对比,进而研究了地面无降雨、有降雨时段两者的风向、风速数据的相关关系及差值。结果得出全年有降雨、无降雨时段两者的风向、风速总体一致性较好,相关性较高,并具有较好可比性和互补性的结论,对了解固定式边界层风廓线雷达探测的准确性,改进观测资料质量控制方法等具有很好的参考价值。

    Abstract:

    The temporal and spatial variation of wind profile radar data and L-band radar sounding data at the boundary layer of Jinan in 2014 were compared by using statistics and correlation analysis. The correlation and difference of wind direction and wind speed of two kinds of data in rainfall and no rainfall were studied, respectively. It can be concluded that, in both scenario, the wind direction and wind speed data obtained by two kinds of observation means have good consistency and correlation, and all have sound comparability and data complementarity. The research has an important reference value for understanding the accuracy of fixed boundary layer wind profile radar detection and improving the quality control of observation data.
