In this paper, 106 severe convective cases with instantaneous wind force no less than 8 grade in the central region of Shandong Province from 2001 to 2016 are analyzed and their climatic characteristics are summarized. The distribution of environmental parameters and forecast thresholds for classified severe convective weather are studied by the form of box and whisker plots. The results are listed as below. The severe convective weather happens more in mountains, less in plains, more in the central region, and less in the northern and southwestern region. Severe convections frequently occur in June (especially mid-June), accompanied with ground convergence line as the main type of trigger mechanism. For thunderstorms, hail thunderstorms, and mixed type of heavy rainfall, environmental parameters such as the mean depression of the dew point between the ground and 850 hPa, 0-1 km and 0-3 km vertical wind shear, SWEAT, LI (lifting index), K index, storm relative helicity, and height index all have different minimum thresholds. The 0 ℃ layer which is prone to severe convective weather is about 4.1 km in the central region of Shandong Province; for the severe convective weather associated with hail, the melting layer is about 0.6 km lower than the 0 ℃ layer. According to the distribution of the above environmental parameters and the intensity change of upper-level and low-level vertical wind shear, the three types of severe convective weather can be distinguished to some extent.
