Initiation Mechanism of Meso-β Scale Convective Systems

Peng Jiayi Wu Rongsheng and Wang YuanKey Laboratory of Mesoscale Severe Weather, Ministry of Education, ChinaDepartment of Atmospheric Sciences, Nanjing University, Nanjing 210093Department of Atmospheric Science, Nanjing Institute of Mete  
With the aid of the Penn State-NCAR MM5 model, the initiation mechanism of meso-β scale convective systems (MCS) is investigated on the basis of simulation of the temporal and spatial thermodynamic structure of the MCS that occurred in Wuhan, Hubei, China and its surrounding area on 21 July 1998. Using the PV inversion method, comparisons among the upper-, middle-, and low-level tropospheric potential vorticity (PV) perturbations, as well as their effects on the initiation of MCS, indicate that the low-level tropospheric PV perturbations play an important role in the triggering of MCS. Further analysis reveals that the interaction between the southwest low-level jet and the gravity-inertia wave indeed initiates MCS in the conditionally unstable ambient atmosphere.
