%X The main study results on torrential rain and mesoscale dynamical analysis in recent years are summarized,which include large scale circulation,the interaction between the large scale and meso-micro scale systems,upper and low level jet,vortex,potential vorticity and convective vorticity vector,helicity and instability,etc.The review on meso-scale dynamical analysis of torrential rain systems manifests that the numerical simulation,transform and budget of energy,vorticity,divergence,vorticity budget,vorticity advection,temperature advection,various instability indexes,etc.,are still the general variables for diagnosing the meso-scale systems.But in recent years,besides the potential vorticity and the helicity are used more effectively than before,some new variables,such as generalized moist potential vorticity in non-uniformly saturated atmosphere,convective vorticity vector,and wind partitioning method in a limited region,are applied more to the meso-scale dynamical analysis of torrential rain systems.
