Bow echo and supercell interaction occurred on 12 July 2005 in Shandong province is analyzed based on Jinan CINRAD/SA radar data. The results show that bow echo and supercell appeared when the horizontal trough turned to longitudinal one and atmosphere is unstable. Wind-profiler products reveal clearly the change of high wind before and after the horizontal trough turning to longitudinal trough. Emergence of rear-inflow notch in base reflectivity map is the signal for bow echo form ation. Typical supercell occurs in the warm area in front of the head of bow echo. They all tend to strengthen after combination. Bow echo can lead to mesocyclones continually. What's more, most of mesocyclones bring hail and strong convective wind gust.
