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.
