Abstract:By utilizing data from 46 automated weather stations, disaster datasets, and detection products of T-lnp and S-band Radar, a total of 332 severe convective weather samples containing short-term heavy rain, thunderstorms, and hail are selected from the period between 2012 to 2021 in Fangshan District. The distribution characteristics of severe convective weather in Fangshan District, including the weather situation, inter-annual and inter-monthly variability, ten-day variation, types of severe convective weather events, timing and spatial patterns as well as their moving paths has been analyzed and summarized. The results shows that: (1) The incidence of severe convective weather has exhibited a fluctuating trend over the past decade; (2) Severe convective weather is primarily characterized by short-term heavy rainfall, which occurs with the highest frequency; (3) The classification of severe convective weather can be divided into five main categories from upper air, with the west wind trough type, Mongolian low vortex low trough type, and northeast cold vortex type having a higher frequency of occurrence; (4) Severe convective weather often occurs during the late afternoon and early evening hours; (5) Severe convective weather is more likely to occur in mountainous regions, particularly along the slopes and at higher elevations; (6) The predominant convective weather paths affecting the Fangshan region originate from the Northwest, Southwest, and Westward directions.
