using conventional observation data, automatic regional station rainfall, satellite TBB data and radar data to analyzing of the heavy rainstorm process occurred on June 24, 2016 in enshi.The results showed that the heavy rain, as the typical two trough a ridge "single resistance type" meiyu circulation characteristics, under the favorable large scale circulation background, in the upper trough, low low-level southwest vortex shear, rapids, surface mesoscale convergence line of mesoscale weather system such as under the interaction, mutual influence, formed the big range of strong precipitation.The storm on the space distribution, local sex is strong, show the obvious mesoscale convective characteristics, radar echo figure on the precipitation properties of hybrid precipitation, rainstorm directly affect the system is in beta scale convection system, and the beta scale convection system in multiple mesoscale convective cloud combined strengthening, time scale of about 5 h.Under the process of heavy rain is on the dry and wet strong atmosphere and unstable condition, meiyu front, boundary layer convergence lines and topographic trough triggered effect will be the accumulation of energy release of strong convective weather, at the same time, the southwest of subtropical high peripheral airflow to the south China sea and western Pacific vapor is transported to the enshi, provides favorable conditions for the beginning of the rainstorm.
