图3 2013年6月4日华北河套地区引发对流的边界层辐合线在不同阶段的雷达反射率图[47] （a）0818 LST，形成阶段（起始10 km）;（b）1358 LST，最大长度阶段；（c）1404 LST，对流触发阶段（首个大于等于10 dBZ回波）；（d）1555 LST；图中红圈给出了辐合线位置，白圈给出了辐合线引发首个大于等于10 dBZ回波的位置；十字灰线交点为河套地区临河雷达站点位置；从内到外的灰色圆圈表示离雷达50 km和100 km的位置

Fig. 3 Radar composite reflectivity of a convective boundary on 4 June 2013 around the bend of the Yellow River in North China[47] The red circles in (a)~(c) highlight the boundary at its formation (first 10 km), maximum length, and convective initiation stages, respectively； The white circle in (c) highlights the first ≥10 dBZ echo of the first convective storm near the boundary； The central intersections denote the radar site, and the range rings are shown at 50 km intervals in gray
