Abstract  In this paper, a heavy convection weather process occurred over Yang-tze and Huai Rivers on May 26, 1982 was discussed. It is found that:1.Under warm-air advection in the upper level and coldair advection in the low level of the troposphere, the source of the heavy convective development could he also provided by the latent-labile energy, if in the low-middle level there is a enough increase in moisture, 2.The source of the heavy convective process in this paper is the latent -labile energy. The mechanism of its release might be as followings:Firstly, the combined air convergence in the frictional layer and orographic effect caused a local severe convection, then the heavy downdraft flow of the local convection resulted in the squall front forming which moreover drove the larger region latent-labile energy to be released to give rise to a large scale of severe convection system in transport.
