Based on the NCEP/NCAR reanalysis data and other conventional observation data, the abnormal characteristics of weather background and meteorological factors of two typical extreme precipitation types (north-south flow convergence type and north-south trough superposition type) in Hubei Province are analyzed. The results show that there is a convergence of the north and south airflow at 500 hPa for north-south flow convergence type. The southerly wind on the south side of the low-level shear line develops extremely strongly and the cold front on the ground enters the warm trough to form a stationary front. The dynamic factors (vorticity at 850 hPa and divergence at 200 hPa) and water vapor factor (atmospheric precipitable water) have significant abnormal characteristics. For north-south trough superposition type, the north and south troughs are superimposed at 500 hPa. There are significant vortex shear formed in the low layer or boundary layer, and the warm and low pressure on the ground develops strongly. The ratios of the abnormal degree of dynamic factors (divergence at 200 hPa and vorticity at 925 hPa) and instability factor (temperature advection at 700 hPa) are high. Finally, two conceptual models of extreme precipitation weather are presented, which combine the weather background and the abnormal degree of meteorological factors.
