摘要
通过对一次强对流天气过程中锋面附近折射场及其特征的分析,结果发现:大气折射指数的时空变化与气团性质、锋面演变、纬度和下垫面性质有关。雷达对锋面两侧进行水平探测不仅存在着探测误差,而且还存在着“探测盲区”。
This paper analyzes the refraction field near the front in asevere convective weather event and its characteristics, indicatingthat the change of the atmospheric refraction index in time and spaceis related to behaviors of air masses, evolution of the front, latitudeand the type of the underlying surface.Using radar to detect both sidesof the front horizontally, we find that there exist not only detection errors but also 'the blind area of detection'.
