摘　　要：热带气旋暴雨突然增幅和特大暴雨往往是酿成洪涝、山体滑坡、泥石流、山洪爆发等巨灾的直接诱因,因此,登陆热带气旋引发暴雨突然增幅和特大暴雨研究受到了气象学者的高度关注,也是热带气旋研究领域的难点之一。着重从以下5个方面系统地综述了国内外相关机理研究的主要进展:(1)行星尺度环流背景、天气尺度系统和中尺度系统的多尺度相互作用;(2)下垫面条件的影响;(3)环境垂直风切变的作用;(4)能量的制造及转换理论;(5)涡旋Rossby波和重力惯性波的激发传播理论。最后对当前现状中的存在问题和未来工作设想进行了探讨。Abrupt rainfall intensification and heavy rainfall associated with landfalling tropical cyclones are often the direct causes of severe disasters such as floods, landslides, mud slides and flashfloods. Therefore, they have been paid much attention to by lots of meteorologists, being regarded as the frontier and the problem in the tropical cyclone research field. In this paper, the main progress made at home and abroad is comprehensively summarized from the five following aspects： （1） Multi-scale interactions between the planetary scale, large scale and mesoscale atmospheric systems; （2） The effect of underlying surface conditions; （3） Impact of environmental vertical wind shear; （4） Energy production and conversion theory; （5） Wave propagation theory. Thereafter, discussions of the existing problems and future work plans are presented in the last section of the paper.
