| 英文摘要 | A squall line on 14 june 2009 in the provinces of jiangsu and anhui was well simulated using the advanced regional prediction system (arps) model. based on high resolution spatial and temporal data, a detailed analysis of the structural features and propagation mechanisms of the squall line was conducted. the dynamic and thermodynamic structural characteristics and their causes were analyzed in detail. unbalanced flows were found to play a key role in initiating gravity waves during the squall line's development. the spread and development of the gravity waves were sustained by convection in the wave-cisk process. the squall line's propagation and development mainly relied on the combined effect of gravity waves at the midlevel and cold outflow along the gust front. new cells were continuously forced by the cold pool outflow and were enhanced and lifted by the intense upward motion. at a particular phase, the new cells merged with the updraft of the gravity waves, leading to an intense updraft that strengthened the squall line. |
