Numerical Modeling and Characteristics Analysis of a Squall Line on 14 June 2009
Based on the radar echo and NCEP reanalysis data, a squall line at June 14, 2009 in Anhui and Jiangsu were analyzed. The radar echo displays “bow shape, the velocity echo shows significant mid-level radial convergence (MARC). It is found that the squall line is shaped by the joint type of discontinuity line and line of rearward continuity, and partial disturbance of the strong convective weather provides a trigger mechanism. By analyzing the evolution of squall line and the precipitation region, it is shown that WRF model could simulate the squall line, reveal the characteristics and evolution of squall line mechanism analysis.
