摘　　要：Madden-Julian Oscillation(MJO)是热带大气在季节内时间尺度上的主要变化特征,MJO对流的活动对全球很多地区的天气和气候系统都有重要的影响,因此MJO是大气科学重要的前沿课题之一.MJO对流的生成过程是MJO研究中公认的最薄弱的环节,文中从MJO的研究背景出发,对MJO对流生成的有关研究工作及其进展进行了回顾与总结,主要包括MJO对流生成的前期信号、MJO对流的数值模拟、MJO对流生成的动力学机制.最后对MJO对流生成研究中还有待解决的问题进行了分析与讨论.The Madden-Julian Oscillation(MJO)is a dominant component of tropical variability at intraseasonal time scales.The activities of the MJO convection have important impacts on weather and climate systems in many parts of the world.The study of the MJO therefore represents one of the frontiers of atmospheric science.Since the convective initiation is the least understood aspect of MJO,this review aims to synthesize and summarize studies of convective initiation of the MJO include but are not limited to:its observed precursor signals,the numerical simulations,and the mechanisms.The focuses of ongoing research and unsolved issues related to MJO initiation are also presented.
