To understand more about the diversities of thunderstorm gust fronts, based on Doppler radar data from Tianjin and Cangzhou, wind profiler radar data from Xiqing and Huanghua, Tianjin Meteorological Tower, surface observations data, as well as VDRAS data, this paper comparatively analyzes the causes and correlation of two consecutive gust fronts that occurred in the Bohai Sea Bay on 10 June 2016. The results show that the structures are quite different between these two gust fronts. For the first gust front (GFⅠ), the near-surface meso-γ scale vortices tended to appear along the leading of GFⅠ, and the strong southwesterly warm-humid air flows from boundary layer and lower-level were transported to the thunderstorm along GFⅠ. For the second gust front (GF Ⅱ), dynamic structure was characterized by two strong inflows. One was boundary layer rear northeast inflow at 150-750 m height, another strong southwest inflow was at 990-2 190 m height. The two inflows induced two separated vertical clockwise circulations at the front and rear of GF Ⅱ. The configuration of cold pool and low-level vertical wind shear played an important role in formation and maintenance of these two gust fronts. The strength of cold pool at the rear of GFⅠ is relatively weak, and the 0-3 km vertical wind shear was stronger than the propagation speed of cold pool. The thunderstorm inclined to a stratiform cloud structure, which was not conducive to further development. Comparatively, for GF Ⅱ, the cold pool developed stronger, the propagation of cold pool was more than the 0-3 km vertical wind shear, thus the updraft in the thunderstorm was more vertical, resulting in intensified storm. Meanwhile, the interaction and inherent correlation between meso-γ scale vortex and cold pool were also obvious. Due to the collision of meso-γ scale vortices, strong low-level convergence and updraft occurred between the two front gusts. Moreover, the consolidation of the two cold pools aggravated low-layer instability, which increased the rotation of the upper and lower layers, and formed strong horizontal vorticity, finally leading to the rapid strengthening of convective storm and evolution into bow echo.
