The mechanism was similar to the equivalent barotropic warm core structure. The Conditional Instability of the Second Kind was the primary mechanism of development and maintenance for MCSs in case 2005. As the MCSs intensified and persisted, the latent heating was highly efficient in producing significant enhancement of Mei-Yu front systems. The LLJ intensified by Coriolis acceleration of ageostrophic wind was induced by the effect of latent heat release. The LLJ and the effect of latent heat released reinforce each other in convection system through a positive feedback process.

综合而言，2005年个案中梅雨锋面结构为垂直近乎不倾斜的浅系统，槽线系统不明显，锋面水平温度梯度微弱，低层具有强水平气旋式风切，较似正压系统，个案中MCS发展及维持机制，主要是透过CISK 过程来维持；其过程是由於低层锋面带上之辐合激发对流发展，对流潜热释放造成局部气压梯度增强，因而增强地转风；而潜热释放亦有利低层辐合之增强，产生非地转风，再透过科氏加速增强西南风，使LLJ增强，形成一正向的回馈作用。

It is shown that the effect of dynamic thermal tensioning by trailing intensive cooling is greatly influenced by the heat-dissipating conditions of the fixtures.Without uniform preheating it is difficult for trailing intensive cooling alone to create a saddle-shaped temperature field and the mechanism of reducing distortion is equivalent to the decrease of welding heat input. While combined with uniform preheating ,dynamic thermal tensioning comes into being to some degree and the effect of reducing distortion increases obviously.
