A super strong cold wave weather process occurred in Guizhou from November 29 to December 1, 2022. This article analyzes the causes of this event and its accompanying strong winds, snow condensation weather, and sharp drop in temperature, by using the conventional observation data and NECP 1°×1° occur reanalysis data, as well as the synoptic principles and synoptic dynamics diagnostic analysis methods. The results show that: (1) This super cold wave weather process occurred in the middle and high latitudes, accompanied by the development of a cold vortex trough with a -48 ℃ cold center moving eastward and southward, which guided strong cold air to move southward, strengthening the subtropical high to extend westward and move northward, and multiple small troughs to shift eastward on the plateau. (2) In the early stage, the development of the thermal low-pressure system deepened, and the high temperature in most areas of Guizhou abnormally rebounded to above 27℃. The 850hPa cold advection was strong and maintained for a long time, which was the main reason for the large cooling amplitude, low temperature, and long cooling duration. The regions with cold advection intensity below -32× 10^-5 ℃·s^-1 were basically consistent with the regions where the minimum temperature drop during the process exceeded 16 ℃ (3) The strong pressure gradient and variable pressure gradient were the main reasons for the formation of the super strong cold wave and strong wind. In the windy area ΔP₃ generally exceeded 3hPa,ΔP₂₄ generally exceeded 10hPa. So, ΔP₃＞3hPa,ΔP₂₄＞10hPa area for the formation of the super strong cold wave and strong wind. (4) The southwest low-level jet maintained and strengthened, continuously transporting water vapor and forming a three-layer structure pattern of warm in the middle and cold in the upper and lower parts of the atmosphere in Guizhou. From 850hPa to ground temperature T＜0 ℃ the southwest low-level jet provided water vapor and temperature conditions for the occurrence and development of snow condensation weather. When 850hPa T⩽-2 ℃ and ground T⩽0℃, the precipitation phase changed from rain to freezing rain, sleet or snow.
