Abstract: Based on the meteorological conventional conobservations and automatic station data from 1981 to 2016, the basic climate characteristics of the Nanchong Gale were statistically analyzed, and the basic characteristics of the weather system configuration and environmental physical quantity of different types of regional thunderstorm gales are emphatically discussed.The results show that:(1) According to the formation reasons, nanchong thunderstorm gales are mainly classified into high-altitude cold advection forcing and baroclinic frontogenesis type, which are divided into city-wide, eastern-type and western-type according to the occurrence of the falling areas.The Eastern type of thunderstorm is mainly caused by high altitude cold advection force, while the whole city and western type of thunderstorm are mostly caused by baroclinic frontogenesis.(2) The baroclinic frontogenesis is mainly caused by the combination of the slanting front and the frontal dynamic forcing caused by the significant cold and warm advection. The forcing type of high-altitude cold advection is mainly generated by the high-altitude strong dry cold advection.(3) Before the occurrence of thunderstorm, the atmospheric environment is in the shape of upper dry and lower humidity, shallow wet layer or bell mouth.For different types of thunderstorms, the physical structure of the environment is different before the occurrence of strong winds.When baroclinic frontogenetic thunderstorm occur, the atmospheric environment is mostly baroclinic. High altitude is often accompanied by strong frontal regions. Considering the large energy of instability in the lower layer, the thermodynamic factors are important.The high-altitude cold advection mainly occurs in the situation of strong cold advection after the Sichuan-Shaanxi trough. The vertical shear of horizontal wind is large, and the vertical shear of the horizontal wind is large, and the temperature of the lower layer is required to increase rapidly. Thermal and dynamic factors are important.
