The results showed thatthe process was a severe convective weather triggered by a supercell storm, which triggered by the intersection of high-level dry and cold air with low-level warm and humid air in the rear of a vortex , and was dominated by hail, thunderstorm and strong wind. Hengshui had maintained an unstable stratification with cold-dry air on the top and warm-humid air on the bottom before the storm was born. The 0°C layer and the -20°C layer were at suitable heights, thus providing a favorable environment for the occurrence and development of severe convection. The northerly wind current in the middle and upper levels had played a good role in pumping and ventilating the current, which increased the transportation of cold and dry air in the middle and upper levels, thereby further increasing the vertical wind shear in the upper and lower levels, and eventually causing the stratification to became even less stable. As the low-level shear line transited, the unstable energy was triggered, which in turn maintainedthe strength of the severe convective weather. The data of the dual-polarized radarcould better describe the particle size, particle shape, and precipitation type, as well as detect and warn of the hail area. By integrating the data of the dual-polarized radar and the Doppler radar, early warning signals of hail could be sent about 66 minutes earlier.

The diffusion coefficient calculated by the average distance formula is appropriately amplified to become the initial diffusion coefficient. Employing a search method, we take two test points in the search interval consisting of 0 and the initial diffusion coefficient. Comparing the errors of the two test points used in the geospatial information diffusion model, we adjust the search interval: if the error of the left test point is small, the left point of the new search interval is unchanged, and the original right point of search interval is replaced with the right test point; if the error of the right test point is small, The right point of the new interval is unchanged, and the original left point of search interval is replaced with the left test point. Repeatedly, the search interval is continuously narrowed until the distance between the two test points is less than a given value, then the search is stopped. Meanwhile, the test point with a small error will be an optimized diffusion coefficient. A case constructing a relationship between the background data and disaster, with a sample size of 30, shows that the diffusion coefficient can reduce error approximately 17%.

Firstly, the local rainstorms belong to the heavy rain caused by summer monsoon moving north, and the distribution of rainfall is extremely uneven, with 3 strong rainfall centers located in Qinhuangdao, Shijiazhuang, and Langfang. Secondly, the difference of heat and water vapor causes the different characteristics of 3 centers: local rainstorm in Qinhuangdao are accompanied by large-scale energy front and water vapor transportation, and radar echoes are banded and mixed; while local rainstorms in Shijiazhuang and Langfang occur at high temperature and moisture environment without large-scale water vapor transportation, and the radar echoes are dense block convective echoes. Lastly, the trigger mechanisms of the 3 strong rainfall centers are different: the local rainstorm in Qinhuangdao is triggered by the shear lines in middle and low level, and multiple convective cells affect successively resulting in “train effect”; while the local rainstorms generated by meso-scale convective systems in Shijiazhuang and Langfang are triggered by the northeast or east wind in the boundary layer.

A comparative analysis of the meteorological observation station(near-shore wind) in the Haigang District closest to this cruise ship terminal and the Qinhuangdao National Basic Weather Station(land wind) shows that when controlled by the weak pressure field, the sea wind speed of Qinhuangdao is generally greater than the near-shore wind speed and the land wind speed about 1 to 2 wind levels. The use of near-shore wind speed to revise the sea wind speed is slightly better than the use of land wind speed to revise the sea wind speed; The sea winds are generally deflected clockwise from the near-shore winds and the land winds.However, it is unrealistic to use the near-shore wind or land wind direction to accurately adjust the sea wind direction.
